The dishwasher does not turn off and the pump is running. BOSCH dishwasher does not turn off: reasons, repairs

Filter problem

If you do not wash the filter in time and food remains are stuck in the machine, the pump may not be able to cope with the task of pumping out water, thereby causing a breakdown. The same situation can arise if the plastic structure of the filter breaks.

This problem will be solved by simply cleaning the filter and possibly replacing it (in the event of a structural failure).

Reason No. 5: automatic leakage protection triggered

Automatic protection against leaks in a dishwasher is a float at the bottom, which, when excess water gets in, opens the damper and the water goes down the drain.

The water leaves, the damper opens, and the water flows again and the damper opens again. This can continue indefinitely in the literal sense of the word. And your search for the location of the leak can also continue indefinitely, just like attempts to remove water from the pan with a rag in the hope that everything will work out.

This may give a temporary effect, but we are unlikely to talk about the normal operation of the dishwasher. At least until you call an experienced technician who will find the leak and the reason for the automatic protection.

These are the top five most common reasons why your dishwasher may not want to turn off at the end of a wash cycle. Although, who knows, behind a closed door you can’t see how well she washed the dishes this time and whether she washed them at all.

For example, if the reason for non-stop operation is the activation of automatic leakage protection, then the accumulated water leaves before it has time to soak and properly wash the dishes loaded into the washing compartment.

A professional master will save you in any case

In general, continuous operation may not be the only surprise that an overly industrious dishwasher will present. To avoid such surprises in the future, contact ALM-remont.

Internal faults

If all of the above faults are excluded, most likely the problem lies inside the machine. In this case, to determine the malfunction and eliminate it, it is necessary to carry out a number of actions:

Turn off power and water supply.
Dismantle the dishwasher. Typically, this requires removing the fixing bolts.
Check the timer, heater and thermostat for electrical continuity. It is possible that one of the parts has failed and needs to be replaced.
Check the programmer. The machine may not turn off if the programmer is faulty. In most cases, it cannot be repaired and must be replaced.
Inspect the motor and pump for blockages. If it is detected, it is necessary to clean it.
Check the pump for wear. If your dishwasher doesn't pump water out well, there's a good chance that the pump doesn't have enough power to operate properly. Don't wait until it completely fails. It is necessary to replace the pump as soon as possible.
Check the motor for damage.
Inspect the drive belt for damage or signs of wear. If the dishwasher has been in use for a long time, the belt may have stretched or become unusable.

If, after carrying out all the above-described manipulations, the breakdown has not been identified, you must contact the service center. Specialists will be able to quickly identify the cause of the malfunction and eliminate it.

The situation is akin to a disaster when a home assistant refuses to turn on. Sometimes the opposite happens. The machine has faithfully completed the washing cycle, washed the dishes, but does not want to turn off and continues to work. It can be stopped by turning off the machine through which it is connected to the network, or by pulling out the power plug from the outlet. The situation is not only unpleasant, but also promises unexpected repair costs. If the BOSCH dishwasher does not turn off, you will most likely need:

Replacing or repairing a control module (board, unit)
If the BOSCH dishwasher does not turn off, the most likely cause is a malfunction of the electronic control module (board or unit). This is a direct consequence of the deviation of the supply voltage parameters (usually amplitude) from the nominal value by an amount exceeding the permissible value. In most cases, the malfunction appears after a sudden power outage and its resumption. Occurring in electrical circuits in the so-called. During the transition period, processes lead to burnout of conductive tracks, passive elements (resistors, capacitors, inductors) and semiconductors. Often the failure of a control module (unit, board) is so serious that the cost of its restoration (repair) turns out to be commensurate with the price of a new unit. In this case, it becomes advisable to replace it;
Replacement (repair) of the drain pump (pump).
If the dishwashing program has ended, but the machine does not turn off - the drain motor continues to function - the pump that pumps water out of the washing chamber (tank) may need to be repaired or replaced. To exclude the possibility of the electric motor windings catching fire due to its long-term continuous operation in an emergency situation, we advise you to disconnect (de-energize) the dishwasher from the mains and call a technician. After diagnosing the malfunction and identifying the root cause, he will determine what to do with the pump - repair or replace. In some cases, you can get by by replacing the sensors involved in the drain pump control circuit.

It should be remembered: an attempt at unqualified repair or reprogramming of the PMM control module or drain pump is fraught with even greater negative consequences, including a fire. Therefore, when a BOSCH dishwasher does not turn off, it is advisable to entrust the problem to an experienced technician from our service center.

First actions

To repair equipment, it is necessary to dismantle it. This is especially important if a built-in device is used. To do this, you need to turn off the electrical power and water supply, and also remove the fixing bolts.

We use a multimeter to test the door and switches for electrical conductivity.
The machine may not start, but the engine may still hum. To fix the problem, the machine must be disassembled. It is necessary to check the motor, pump, and check for blockages. It doesn’t hurt to check the drive belt, which could have stretched or worn out if the dishwasher has been used for more than one year.

The programmer is broken. The program may not start due to the failure of the programmer. To fix it, you will have to contact specialists, since repairing this element yourself is hardly possible.
Water does not flow into the working chamber. As noted, the valve may simply be closed or the hose may be pinched. It wouldn’t hurt to check the inlet filter, which might have become clogged.

What to do if the machine does not turn off? Most likely, the reason lies in the failure of the electronics. It is also possible that the outlet filter may become clogged, causing the water to not drain and causing the dishwasher to stop working.

Professionals will help

If simple steps do not help eliminate the emerging problem, you need to contact a specialist. Having knowledge, experience and all the necessary tools, they can fix the breakdown quickly, determining the exact cause. At the same time, a qualified workshop will always provide a guarantee for its service.

And additionally about what to do if the dishwasher does not turn off or does not turn off

Replacing or repairing a control module (board, unit)
If the BOSCH dishwasher does not turn off, the most likely cause is a malfunction of the electronic control module (board or unit). This is a direct consequence of the deviation of the supply voltage parameters (usually amplitude) from the nominal value by an amount exceeding the permissible value. In most cases, the malfunction appears after a sudden power outage and its resumption. Occurring in electrical circuits in the so-called. During the transition period, processes lead to burnout of conductive tracks, passive elements (resistors, capacitors, inductors) and semiconductors. Often the failure of a control module (unit, board) is so serious that the cost of its restoration (repair) turns out to be commensurate with the price of a new unit. In this case, it becomes advisable to replace it;
Replacement (repair) of the drain pump (pump).
If the dishwashing program has ended and the machine does not turn off - the drain motor continues to function - the pump that pumps water out of the washing chamber (tank) may need to be repaired or replaced. To exclude the possibility of the electric motor windings catching fire due to its long-term continuous operation in an emergency situation, we advise you to disconnect (de-energize) the dishwasher from the mains and call a technician. After diagnosing the malfunction and identifying the root cause, he will determine what to do with the pump - repair or replace. In some cases, you can get by by replacing the sensors involved in the drain pump control circuit.

What to do if the dishwasher won't turn off?

Make sure that the machine is really frozen or faulty. You may have changed the mode yourself, so it works a little longer than usual. If the mode has not changed, and the machine does not complete the wash or does not even start it, the first thing to do is:

disconnect the equipment from the network;
remove the dishes (as a rule, after switching off, the locking device stops holding the door);
drain off any water if any remains.

In the future, you need to call a technician who will check the main components. If you have electrical experience, you can try to check the control unit yourself.

Most often the problem is caused by a faulty or malfunctioning pump. Operation may be affected by a hose that is too long or blocked, the slope of the ELECTROLUX dishwasher and other factors. The pump itself may also break.

Preliminary actions

When a problem is discovered, you should not immediately disassemble the device to look for the cause of the failure. More often than not, everything is much simpler. Therefore, it is recommended to perform the following operations:

Checking the power supply. First you need to make sure that the power button is pressed. It may seem funny to some, but quite often housewives simply forget to plug the plug into the socket and call a technician to fix the problem. To avoid getting into such an awkward situation, you need to carry out preliminary manipulations. If the plug is on, then you need to check the socket. You should connect another electrical appliance to it to make sure there is voltage in the network. If the device is working, you should check the dishwasher's power cord to see if there is damage.

Checking water supply and drainage. Often the drain or water supply hose is kinked, making it difficult or impossible for fluid to move. Therefore, you need to inspect the hoses. You should also check the tap to see if it is open to supply water to the device.
The door is not closed. The dishwasher may not turn on as a result of the door not being closed tightly. Something could have gotten between it and the device body, for example, sealing material or a broken lock. The breakdown requires repair.
Pressure in the water supply system. A low reading may cause the dishwasher to fail to operate. Therefore, it is very important to check this parameter before purchasing equipment.
