The dishwasher is constantly draining water. why is this happening and what to do in this case

We will deal with the symptoms and causes of breakdown

It is quite difficult to draw a line between symptoms when the dishwasher does not wash the dishes well or stops washing them altogether. We will consider them together, since the nature of such errors often turns out to be the same. What happens to the dishwasher in this situation?

The washing program starts, runs and ends, and at the exit the dishes not only remain dirty, they almost never get wet.
After completing the program, the dishes are wet and completely dirty.
The dishwasher works in a specific mode, but the dishes are washed unsatisfactorily.

In this case, the main negative factor will be that the dishes remain dirty. But you need to understand that time wasted, electricity, water, and your nerves were wasted in the end. As a result, it turns out that this breakdown is even worse than if the dishwasher simply did not turn on - there are more harmful consequences. So what causes the above symptoms?

These or those user errors, we will talk about them a little later.
Diverse water supply problems.
Impossibility of normal circulation of water inside the dishwasher.
Difficulty drawing up dishwashing liquid.
Breakage of the heating element, if there is no temperature sensor in the machine.
Breakage of the spray arm (impeller).

The reason lies in user error

According to the masters of the world's leading service centers, the main reasons why the dishwasher does not wash the dishes are various mistakes that users make during the operation of the dishwasher. The most common errors are as follows.

The dishwasher is not cleaned on time, or the user does not clean it at all.
The user places the dishes in the baskets incorrectly.
The user puts detergent in the wrong compartment of the cuvette, or uses an unacceptable detergent.

incorrectly lay out the dishes in the basket;
put large items in the upper basket and small ones in the lower one;
put individual items on the bottom of the dishwasher tank, next to the rocker;
position the dishes so that they touch the detergent drawer.

Each of these errors leads to at least poor quality of dishwashing, and at the most to breakage of the moving element or valve of the detergent drawer. It is also a gross mistake to use inappropriate means. Some people, in an effort to save money, pour all sorts of rubbish into the car, thinking that it will help clean the dishes. In our opinion, using homemade powders and rinses is acceptable, but they must be prepared according to proven recipes and use safe chemicals.

In particular, it is unacceptable to use mustard powder instead of detergent. After the first wash, the nozzles of the rotating rocker arm will clog with mustard and dry out. After that, if they are not cleaned, the next dishwashing will be more than unsuccessful.

Why does the dishwasher constantly drain water?

Among the options for malfunctions, the problem when the dishwasher, instead of switching to the washing mode, constantly drains the water, is one of the most common. This is most often caused by a leak. Before proceeding with the search for specific causes and elimination of the malfunction, you must make sure that there is a leak.

Signs of a leak

There are several characteristic signs that will allow you to establish the presence of such a defect. Most of them refer to devices equipped with the Aquastop electromagnetic system, which are most common today, for example, Bosch or Electrolux.In addition to the constant transition to drain mode and the characteristic noise from a running pump, the dishwasher:

will display the corresponding malfunction code on the display, which is easy to decipher according to the instructions;
stop responding to commands from the control panel;
will not respond to attempts to restore through a reboot;
will pour water into the sump.

Causes of malfunction

The presence of all of the listed signs or some of them confirms water leakage by almost 100%. If they are found, it is necessary to establish the cause of the leak. There may be several of them:

malfunction of Aquastop;
breakage of the water supply valve;
failure of the control board;
cracks in pipes or tank;
wear of the oil seal of the circulation pump.

Aquastop malfunction

The Bosch dishwasher or its counterparts from Electrolux are equipped with an electromagnetic Aquastop, where, in addition to the valve, there is a tray with a float and an overflow sensor.

When it is full, a sensor is triggered, which stops the water supply and starts the pump for pumping out.

Malfunctions can occur when Aquastop is triggered or scale build-up on the float, which presses it to the sensor. To eliminate the defect, you must:

turn off the power;
shut off the water supply;
push the device into a free space for easy manipulation;
tilt the machine to pump out the water from the pallet.

Scale detection will require its removal in order to fully restore performance.

Broken water supply valve

Another reason for this situation is a faulty filling valve. When the wash starts, the valve receives a signal and starts the water supply, the opposite signal should lead to its closing. When this does not happen, water continues to flow, the pump periodically turns on to pump out excess liquid. You can check the functionality of the device as follows:

turn off the feed valve;
after the pump stops working, turn off the power;
we provide access to the connection point of the inlet hose;
disconnect it from the car;
we check the electrical part of the valve with a multimeter.

Control board

Signals for operation in the mode of filling the machine and subsequent draining are received from the control board, where the relay or triac of the pump is located. If it fails, the program crashes. This is a more complex breakdown, the elimination of which will require special knowledge and experience.

Cracks in pipes or tank

Constant overflow followed by drainage can be triggered by cracks in the pipes or tank. In this case:

the water level in the feed hopper is constantly rising;
the upper drain valve rises, passes it into the pan;
a sensor in the pallet triggers the drain.

The breakdown can be eliminated only by replacing the damaged structural element. To do this, you will need to disassemble the machine, identify the leak and replace it.

Worn oil seal of the circulation pump

The circulation pump provides a forced flow of water in the machine. The wear of its oil seal is not the main reason for overflows, but under certain conditions it can lead to a characteristic failure. In most cases, the pump is non-separable and the oil seals are not supplied separately. Therefore, to restore the functionality of the device, the pump is replaced entirely.

The reasons for the inoperability of the PMM are far from always possible to identify and eliminate on their own. Many of the breakdowns require a professional approach, special tools and equipment.

In their absence, you should not try to find the answer to the question of what to do on your own, without the invitation of a specialist.

An attempt to save money on small things can cost significantly more than the services of a service center and turn into the need to purchase a new device.

How to forcibly drain the dishwasher?

If it was found that the water from the PMM is not drained to the end, water remains in the sump at the bottom of the machine, the first action is the forced removal of water.Otherwise, no repair work is possible.

The main way is the in-house command to drain:

turn on the drain program on the control panel;
waiting for the end of the procedure;
turn off the machine, de-energize, shut off the water.

This is how complete conservation of PMM is carried out before a long period of inactivity, for example, for the winter. However, if the drain system does not work, this method will not work.

Then the question is solved differently:

The power supply is cut off, the water supply is cut off, the sewage system is disconnected.
The front door opens and all trays and baskets are removed.
The waste filter is removed and cleaned.
The stopper is removed from the ion-exchanger tank (where the salt is poured). A rubber hose is inserted into the hole, the other end of which is lowered into the prepared basin.
With the help of a syringe, a vacuum (suction) is created in the hose, due to which water begins to pour into the basin.
After waiting for all the water to drain, repeat the procedure by lowering the other end of the hose into the hole from the filter.

This procedure allows the PMM to be completely freed from water, after which it can be safely repaired or transported to the workshop.

Instead of a syringe, you can use a rubber bulb to pump diesel fuel. You can find out more about the forced draining of water from dishwashers of different brands in this article.

Hansa

Forced discharge from Hansa PMM is carried out according to the general rules. There are no specific requirements. Water is removed from the ion exchanger and the filter hole.

In addition, it is recommended to disconnect the outlet from the pump and drain the water from it (there is quite a lot of it left there). This action is especially recommended in cases where the car will have to be taken to a service center for a long time in winter conditions.

Burning

The forced draining procedure is carried out in the usual way (using a hose).

There is no forced drain function in the PMM, and a special drain plug is not provided. This sometimes causes a lot of inconvenience, but it also has its own reasons.

For example, the rarity of using such plugs is taken into account, as well as the risk of leaks. Therefore, manufacturers prefer to abandon unnecessary holes and ensure the tightness of the bottom of the pallet.

Electrolux

To the right of the pallet there is a filter in the form of a mesh cylinder. It is immersed inside, so only the cork is visible from the outside. It must be unscrewed, and a hose for pumping water should be lowered into the hole.

You can use a powerful vacuum cleaner, a rubber bulb, or a syringe. When all the water can be drained, it is recommended to remove the remaining water from the pump, in the case of which about 50-100 ml often remains.

Siemens

If you need to forcibly discharge the water during a program, you must first reset it and then close the door. There is a Reset combination on the control panel (usually, these are two buttons that must be pressed simultaneously).

On more modern models, the reset is carried out by pressing the "Start" button (hold for a few seconds), after which the door must be closed. The program is usually reset by holding down the selection button (for a few seconds).

If the machine does not work at all, they act by sucking water using a rubber hose.

Samsung

The procedure for draining water in the Samsung PMM takes place either in normal mode (resetting the program and closing the door), or in emergency mode (ordinary pumping out water from the hole for the garbage filter).

The first option is used if the PMM works and is capable of executing commands from the control module. The second option allows you to drain the residues from a completely de-energized and inoperative machine.

There is no special program for emergency water discharge, since any stop automatically starts the drain, so there is no need for duplicate programs.

Bosch

To remove water from the Bosch PMM, the standard method of suction from the sump and ion exchanger is used.No additional action is required, the only recommended addition is the drying of the inner cavity (sump) in order to exclude the formation of condensation.

Read how to drain the Bosch dishwasher here.

Zanussi

Drainage of water from all PMM Zanussi models occurs either using standard means (drainage system), or by mechanical pumping from internal cavities.

The first option is preferable, but if the machine does not drain the water in the usual way, you have to pump it out using a rubber hose and a pear.

The procedure is simple, but requires complete removal of all trays and baskets from the inside, unscrewing the filter and the lid of the ion exchanger.

Is this a problem or a norm?

In fact, there should always be some liquid in the dishwasher brine compartment.

This is necessary to prepare a softening solution, therefore a certain amount of water in the compartment is the norm.

The instructions for any typewriter say that when you first start a new device, you need to pour water into this compartment, and pour salt on top, which will then displace excess water.

She must go down the drain. In addition, there is some water in other parts of the machine to ensure the safety of its rubber parts from drying out.

In the compartment of a medium-sized machine, approximately 1-1.5 kg of substance is placed at a time. This amount is enough for about 1.5-2 months.

Some dishwasher models have an indicator that indicates the water hardness level. When the salt runs out, the indicator will remind you of this. This means that you need to fill up a new batch.

The saline solution should not overflow over the edge of the compartment, if this happens, you need to remove it from the metal surface of the camera with a soft cloth and wipe it dry.

It is impossible to leave the solution, its concentration is such that it can quickly spoil metal parts.

Reference! Thus, the volume of water to be poured into the compartment should not exceed 1-1.5 liters.

Diagnosing the causes and troubleshooting the dishwasher

The most common reasons a dishwasher won't draw water include:

a loosely closed door, as the door lock has broken;
the filter is clogged;
the Aquastop system blocked the fluid supply;
the temperature sensor has broken or the heating element has burned out;
problems with the control module;
the filler valve is out of order;
the water level sensor has broken.

Some of the causes can be corrected by yourself, for example, by cleaning the filters. More complex breakdowns require some knowledge and special tools.

The door is not closed securely

The appliance door has a lock that protects it from leaks. When it is closed, the door lock signal is sent to the control module, the machine starts to work. If the lock is broken, then the door does not close until it clicks. The blocking signal is not received, the program does not start and the liquid is not drawn.

If the lock breaks down, you can change it yourself. How to do it:

the dishwasher is disconnected from the mains;
unscrew the front panel;
unscrew the broken door lock;
install a new latch;
screw the panel.

Clogged filter

An inlet valve filter is installed to protect the equipment from dirt and debris that comes from the water supply. It is periodically cleaned or changed. If the liquid is drawn into the dishwasher too slowly or does not flow at all, then the reason is most often a clogged filter. They clean it on their own or call a master.

Shut off the water supply before cleaning. Unscrew the hose, take out the filter. It is located at the inlet of the intake valve. The mesh is washed under running water. In case of severe contamination, clean it with a needle or dipped in a citric acid solution (30 g per 1 liter) for an hour.Then the cleaned filter is reinstalled, the hose is connected.

Aquastop worked

Dishwashers are equipped with a leakage protection system - Aquastop. The reasons why the technique stops working:

the solenoid valve blocked the water supply, as there was a leak;
the system itself is out of order.

If a leak occurs and the liquid enters the sump, then it will be eliminated. For this:

disassemble the car body;
tilt the body by no more than 35 ° C and drain the liquid;
the device is left to dry completely (for 10-12 hours).

In case of failure of the system itself, it is repaired by professional craftsmen. Solenoid valves often burn out. Their integrity is checked with a multimeter. If it shows infinite resistance, then the valve is burnt out. Replacement is carried out in a repair shop.

Defective temperature sensor or heating element

With a faulty temperature sensor (thermostat) or heating element, water begins to accumulate, but then washing stops. This happens because the liquid does not heat up to the temperatures set by the program. Diagnostics and replacement of the thermostat in the dishwasher, as well as the replacement of a burnt heating element are performed by qualified specialists.

Control module problems

The control module of the device is located under the front panel, in the door. He issues commands to systems, monitors the observance of washing regimes. In the event of a module malfunction, the equipment stops working or malfunctions.

To check the integrity of the plateau, the door is disassembled. Defects are visually determined. The faulty module is reflashed or replaced by qualified specialists.

Filling valve defective

When the dishwasher starts up, the control module sends a signal to the inlet valve. It opens and the liquid is poured. If the pump hums but does not pump, then the valve is clogged or damaged. They clean the blockage themselves or invite a specialist.

The damaged valve is replaced, since it cannot be repaired. In addition to damaging the valve, an open circuit from the control unit is possible. Diagnostics and replacement are performed by the master.

Faulty water level sensor

Faulty water level sensor (pressure switch) delivers distorted information about the liquid level to the control unit or does not give signals at all. If the signal is given that the tank is full, although this is not the case, then no more water will flow. In the absence of signals, it also does not come. In this case, the pressure switch is changed.

You can replace it yourself:

the equipment is disconnected from the mains;
turn over and remove the pallet;
visually determine the presence of defects on the sensor;
check with a multimeter: lack of voltage indicates a malfunction of the pressure switch;
the broken sensor is replaced with a new one.

Checking and replacing the pump

If the Bosch dishwasher does not drain the water and the sound of the pump is not heard, you will have to check and, possibly, replace this part. For this:

Remove water from the PMM chamber in any convenient way.
Remove the drain filter.
Lay the clipper on its side.
Remove the pallet and disconnect the Aquastop sensor from it.
Remove the pump and disconnect the pipes from it.
Check the impeller (it should rotate freely). If it sticks, replace the pump.
Check the resistance at the pump contacts with a multimeter. It should be within 200 ohms if the pump is working properly. Otherwise, the pump must be replaced.
Make sure the pump is supplied with voltage from the control box. If not, the ECU may be defective.

Removing the pump for diagnosis and replacement

In conclusion, I would like to note that it is better to entrust the diagnosis and replacement of such faulty parts as the pump, pressure switch and ECU to qualified craftsmen. They have the experience and the right tools to test, so you don't have to look for original parts for repairs.

How to fix the problem

Situations where water does not drain from the dishwasher often arise due to improper use.Sometimes the reason is the wrong connection of the dishwasher or the breakdown of individual components. If the filter is clogged or the hose is bent, it is easy to fix the problem yourself. Only a master can fix a breakdown of a part or a system unit.

Clogged filters

This problem occurs more often than others. Therefore, the first step is to check the state of the purification system. It becomes clogged very quickly due to the accumulation of food debris on the filters.

Advice!

To prevent clogging, the dishes are cleaned of food debris before placing them in the dishwasher. This significantly increases the uptime.

The filters located at the bottom of the device are easy to remove and rinse under running water. After cleansing, they put it back and pour in 3 glasses of water. Include pumping out of the waste solution. If the liquid is removed, then the malfunction has been eliminated.

Drain hose problems

This part connects the sewer to the drainage system of the appliance and is located at the back of the appliance. If the hose is pinched, water will not escape. The dishwasher is unplugged and moved away from the wall. If a visual inspection reveals pinching of the hose, eliminate it.

Sometimes the drain hose becomes clogged with small debris after prolonged use of the machine. Then the tube is disconnected from the sewer and sent to the bucket. The dishwasher is turned on at the sink and its character is assessed. If the liquid escapes under pressure, it means that a blockage has formed in the sewer itself. A weak trickle indicates a blockage inside the hose. In this case, clean it.

Problems in the word pump and drainage system

The drainage system is checked in the same way as the drain hose. With good pressure, it functions normally. A weak jet indicates the need for cleaning. It is more difficult to check the drain pump, since in some PMM models it is located in an inconvenient place. Then for its dismantling it is necessary to involve specialists.

If it is possible to unscrew the pump yourself, it is checked for clogging. If a plug is found, remove it and check the impeller with a pencil

Do this carefully so as not to damage the device and not get hurt by small pieces of dishes that may be in it.

After that, the pump is installed back and the possibility of pumping out the solution is checked. If the liquid still remains at the bottom, a technician is called to fix the problem.

Breakdown of the pressure switch

It happens that liquid is not pumped out due to a breakdown of the level sensor. To check it, a small plastic container is disassembled, which is a pressure take-off chamber. Blow out the transparent tube and, after connecting it to its original place, blow again. There is no breakage if a click is heard.

Breakdown of the electronic system

Sometimes the reason for the water remaining at the bottom of the machine is the breakdown of the software module. This device controls all processes carried out by the machine. He issues commands to the rest of the nodes to carry out their tasks. If a software module breaks down, the machine stops working efficiently.

Important!

If the liquid does not drain after checking all other systems and continues to remain at the bottom, in the salt compartment or other parts of the dishwasher, the program module is checked at the service center. It is impossible to carry out this procedure on its own.

Modern models of dishwashers are equipped with a display on which error codes appear in the event of a breakdown. By the numbers that appear, you can accurately determine the problem and how to fix it, if you look at the instructions for the device.

Reasons why the machine does not drain water

First of all, let's decide on the question, how much water should remain at the bottom of the dishwasher after the end of the washing cycle in a normal situation? The manufacturer does not always indicate in the instructions that water should remain in the dishwasher,and consumers are in a hurry to spread panic out of the blue.

Experts say that in a normal situation, a puddle of about 1 cm deep should remain at the bottom of the dishwasher in order to prevent the sealing gum from drying out. In a confined space, water will slowly evaporate, moistening the walls and ceiling of the washing tank with condensate, and therefore the sealing material in a circle. Wet rubber bands will remain elastic for a long time, which means they will not let water through. If there is clearly more water in the dishwasher and at the same time there are food residues floating in it, then there is a problem that needs to be solved.

Experts identify a number of reasons why the machine does not drain the water. These are the reasons.

The drain hole is too high from the floor and as a result the drain hose is positioned incorrectly. In this case, the pump cannot pump out the waste water normally, and dirty water, albeit partially, remains at the bottom of the washing tank.
There is a blockage somewhere in the system. The filter mesh, nozzle or hose can become clogged, in any case you will have to disassemble and remove the clog, otherwise the water will not go away well.
The water level sensor has broken, so the dishwasher control unit does not know about the amount of water remaining in the washing tank and, as a result, does not command the pump to pump out water.
The pump does not work normally. If the pump breaks down completely, then the dishwasher will not be able to wash the dishes at all, since the water will not be pumped out at all. But if the pump works, then it does not work, the dishwasher will continue to carry out the washing program, but it will not be able to drain the water normally.

In 997 out of 1000 cases of poor water drainage in the dishwasher, the above reasons take place. But in about 3 cases out of 1000 we are talking about the most serious breakdown of the control module. If none of the above cases suits you, contact a good master.

Signs of a leak

There are several characteristic signs that will allow you to establish the presence of such a defect. Most of them refer to devices equipped with the Aquastop electromagnetic system, which are most common today, for example, Bosch or Electrolux. In addition to the constant transition to drain mode and the characteristic noise from a running pump, the dishwasher:

will display the corresponding malfunction code on the display, which is easy to decipher according to the instructions;
stop responding to commands from the control panel;
will not respond to attempts to restore through a reboot;
will pour water into the sump.

Most common problems.

What causes the leak? A leak does not mean a puddle under the car. Sometimes there may be:

Drops on the floor after the dishwashing process.
Condensation from water vapor. Steam accumulates on the door of the appliance, and after opening the door, it falls on the floor in the form of water.
Moisture appears under the device.

Any problem can be solved. Drops on the floor may be caused by condensation. It's just that when you open the door, they hit the floor. This does not mean that the dishwasher is leaking or broken. Another problem is if condensation constantly accumulates at the bottom of the device. In such cases, you should wait a while after the device is working, and only then open it. Wait for the condensation to evaporate completely. And if drops appear on the door, they can be wiped off with a towel or dry cloth.

We remove the blockage and change the pump

So the dishwasher won't drain the water, what should I do? Disconnect it from the mains. Next, inspect the car for blockages, it is best to start with the drain hose. Disconnect it from the sewer and lower it into the bucket, if water has gone, then the siphon or sewer is clogged. If the water does not go, look for a blockage in the dishwasher itself. First clean the filters, here's what to do:

open the door of the machine and take out the baskets for dishes;
unscrew the cover of the filter located at the bottom of the tank of the machine and pull out the filter cup;
then pull out the mesh;
rinse the "glass" and the mesh under running water, if necessary using a toothbrush and dishwashing detergent;
then unscrew the lid of the drain pump and carefully check with your finger how the impeller rotates, it is possible that debris has also got into it, be careful, as not only seeds from fruits can get there, but also small fragments from dishes;
close the pump.
put the filter back in place.

If, after starting the dishwasher, the water still stands, it means that you need to look for the cause in the internal parts and, above all, in the pump. Let's describe how to get to it.

First, you will need to drain the dishwasher by manually scooping it out of the tank or tilting it forward to drain the water.
We take out the drain filter again.
Then we turn the car over "on its back" and remove the pallet, which is attached with self-tapping screws.
Disconnect the sensor, remove the pallet to the side.
Now we unscrew the pump and remove the hoses from it.
Next, we check the impeller, which should rotate intermittently. If there is no rotation, then it is better to replace the unit.
Then check the resistance by connecting the multimeter test leads to the pump terminals. Normally, the resistance should be about 200 ohms. Check if voltage is being supplied to the pump from the control board.
If the pump is faulty, then it is best to buy an original spare part for Bosch or Ariston and put it in its place of the non-working one.

Checking the pressure switch and program module

When there is water in the sump and does not leave, then the water level sensor may be the reason. If a defect occurs in the pressure vessel or in the tube connected to the pressotat, the amount of water in the dishwasher will be distorted. And with a full pan of water, the sensor may not send a signal to the control module, as a result, the pump will not work, water will remain in the tank. In this situation, it is necessary to replace the pressure switch in the dishwasher.

As you can see, the control module is involved in the water drain chain. Therefore, if it fails, then the water will not merge. This could be a short circuit, wear on the device, or a bug in the firmware. In general, a software module is the most complex and expensive part in a typewriter. And it is better to entrust the work of replacing it to a specialist, perhaps it will even be possible to repair the part.

So, having eliminated the reason that there is water in the dishwasher tank, you need to start a test wash and check whether the machine is working, whether the water is drained. We hope that the article was informative and thanks to the enthusiasts who post videos on how to repair a Bosch dishwasher, Ariston, Indesit or any other dishwasher with your own hands.

Preventing the recurrence of the problem

In order to prevent the problem from reoccurring, you need to follow some rules for operating the dishwasher:

Do not bend or squeeze the water supply hose. Before turning on the machine, it must be checked.
The intake filter needs to be cleaned periodically. Once every 3 months, you need to remove the hose and rinse all the nets.
It is necessary to exclude drops in electricity, due to which the control module may become unusable

If, due to the inclusion of the dishwasher, the load on the network increases greatly and the machine on the electricity meter is triggered, it is worth replacing the wiring.
It is important to handle the door carefully during operation to prevent damage or clogging of the lock.
It is better not to install a cheap Aquastop system, they quickly deteriorate and sometimes work for no reason.

How to check and start draining the water in the dishwasher?

If the dishwasher does not drain the water. And you need to turn on the forced drain. This procedure is performed in different ways, depending on the brand and model. For dishwashers Bosch, Siemens, Neff. You must reset the program and close the door. For older models.This program reset is carried out by pressing two washing programs at the same time. On the panel, they are marked with a line and the inscription RESET.

For modern models. Press and hold the start button for a few seconds and close the door. If there is no blockage and the pump is working properly. The water should be drained within 1.5 minutes. For dishwashers from other manufacturers, forced draining can be performed by canceling a program and starting another one. (water draining at the beginning of any cycle) Program cancellation is carried out frequently by holding the program selection button. Or another combination. (see instructions) In some dishwashers. To cancel the program. The dishwasher just needs to be switched off and on again.

How to drain the dishwasher

All the water that remains at the bottom of the dishwasher. When starting the drain pump. Pumping down occurs. Water passes through the filter (if it is not clogged) Then through a special hole in the bottom of the dishwasher. Dragging on into the drain pump itself and already on the other side of the drain pump enters the pipe. There may be a non-return valve on the branch pipe. (Rubber plug that prevents water from entering the drain hose. Back into the dishwasher)

The drain hose can be made up of several small hoses. But eventually the water gets into the main hose. And already goes directly to the siphon. If food debris accumulates in any of these areas. A blockage occurs. The pump is running. But the water doesn't go away. Or it leaves very slowly.
