Bosch dishwasher does not turn off

When a Bosch dishwasher fails to turn off properly, it can be very annoying. Dishwashers are designed to make our lives easier, not harder. You’re not alone if you’ve ever found yourself starring at your dishwasher and wondering why it won’t turn off or is still operating. This problem affects many people, and knowing why it occurs can help you fix the appliance and get it back in working order.

A common cause of this issue is an electronic component or control board malfunction in the dishwasher. These components may occasionally malfunction or become stuck, leaving the dishwasher to run nonstop. The door switch or latch, which is intended to only keep the dishwasher running when it is securely closed, is another possible problem. The machine might not realize that it needs to stop if this latch is broken.

There’s also a possibility that the issue is related to the drain pump. In the event that the pump is malfunctioning, the dishwasher may not finish its cycle and may continue to run. Occasionally, this problem can be fixed by clearing the filter and making sure no debris is obstructing the pump. Maintaining a well-maintained Bosch dishwasher requires timely repairs as well as routine maintenance.

It’s okay if you’re having this issue. Troubleshooting and familiarity with common issues can help you identify and resolve problems more easily, or at least provide you with a better idea of what might be wrong. Remember that the best way to handle appliance malfunctions such as this one is to remain composed and methodical.

The inability of your Bosch dishwasher to turn off is frequently the result of problems such as a broken control panel, a stuck button, or a troublesome door latch. In order to resolve this, you might have to troubleshoot each of these parts in order to find the source and the best solution. Investigating these possible issues will assist you in getting your dishwasher operating again.

Probable causes of the malfunction

It is not necessary to call a technician right away if you discover that the dishwasher is not turning off. Software malfunctions are frequently the root of the issue. It happens when there is a sudden loss of power in the home or a sharp drop in voltage in the network. Restarting the dishwasher will assist in this situation.

Restarting the dishwasher requires that you:

• disconnect the dishwasher from the network;
• wait 15-20 minutes;
• turn on the machine and start the cycle.

Restarting won’t solve the issue, so there must be a malfunction. Let’s examine common issues with the dishwasher’s "behavior."

• Pump failure. Probably, the pump does not receive a command from the control module and does not start draining water into the sewer. Therefore, the dishwasher continues to work.
• Problems with the control module or wiring. Perhaps, the triac coordinating the operation of the drain pump has failed. Also, the reason may be a damaged cable, due to which the units do not receive commands from the unit.
• Faulty pressure switch. The level sensor can transmit incorrect information to the "brain" regarding the amount of water in the working chamber. Therefore, the module does not give a command to drain the waste liquid.
• Errors during installation of the dishwasher. Some Bosch models are sensitive to tilting the case. If you do not install them level, they may not work correctly.
• Illiterate connection of the drain pipe. Probably, due to errors during installation of the dishwasher, a "siphon effect" is observed. The waste liquid, not having time to get into the sewer, is thrown back into the dishwasher chamber. Therefore, the pump does not stop pumping out water.
• Clogged drain system. The pump will try to drain water into the sewer despite the garbage plugs. Because of this, the program execution time can increase significantly.
• Activation of the Aquastop system. If a leak is detected, the dishwasher may react by displaying the E15 error on the display. Sometimes the machine will simply automatically start the pump, which will begin to pump out water.

Issues related to the dashboard should not be disregarded. Additionally, the wash does not stop in this scenario, and the user cannot interact with the "dashboard"’sbuttons. In this situation, what should I do? It is necessary to examine if the controller’s triacs are functioning correctly and if the contacts are oxidized.

Incorrect connection to communications or blockage

It is crucial that you install the dishwasher according to the manufacturer’s instructions. Certain Bosch models are prone to case distortions. As a result, the gadget needs to be set up on a hard, level surface. Tighten the dishwasher’s feet to change its position if needed.

Next, confirm that the dishwasher is correctly connected to the sewerage system. If the drain hose is not 50 cm above the floor, waste water might find its way back into the dishwasher bin. In this instance:

• disconnect the drain hose from the dishwasher body;
• check the corrugation for blockages;
• reconnect the drain hose, placing it at the required height and with a bend.

If the dishwasher drain hose is longer than two meters, the pump will have to operate under more load.

An internal blockage could be the cause of the dishwasher’s behavior. Cleaning it by yourself is simple. To carry out this:

• de-energize the dishwasher;
• open the machine door;
• take out the baskets;
• find the drain filter (it is located at the bottom of the washing chamber);
• clean the filter unit from debris and dirt;
• there is a hole behind the filter – remove the water that has accumulated in it with a sponge;
• remove the protective cover;
• clean the impeller from debris (sometimes a foreign object that gets inside blocks its operation);
• replace the filter unit.

You will need to inspect the pump if the machine is still unable to finish the program after this. To identify the drain pump’s condition:

• de-energize the dishwasher;
• close the shut-off valve;
• disconnect the inlet and drain hoses from the machine;
• lay the dishwasher on its side;
• remove the bottom of the housing by unscrewing the bolts;
• loosen the clamps of the drain pipe, unhook it from the pump;
• remove the bolts securing the pump;
• remove the pump from the dishwasher body.

Examine the pump for flaws. Disassemble the part’s body and remove any debris from the "insides." A malfunctioning pump must be replaced because it cannot be fixed.

The pressure switch is clogged with dirt

The most common cause of the level sensor transmitting inaccurate readings is a blockage in the pipe. The pressure switch is a circular component with contacts and a membrane inside. From the relay to the tank is where the nipple goes.

The pressure switch nipple gauges the amount of water in the hopper by responding to pressure drops in the washing chamber.

Measurement errors occur when the sensor tube becomes clogged. Cleaning the nipple with your hands is simple. All that needs to be done is blow out or wash under running water. The pressure switch is next to the circulation pump in a plastic box.

Repair of the control board

The typical symptoms of this malfunction differ slightly from the previous ones that were covered. The dishwasher starts in this instance and then freezes. After that, pressing the buttons on the dashboard becomes unresponsive, and disconnecting the cord from the network is the only way to turn the machine off.

A specific section of the module is activated by pressing each button on the user interface. If the machine is unresponsive to commands, there could be a problem with the tracks, oxidation on the control board’s triacs, or stuck keys. Under this situation, PMM repair will be necessary.

The control module for the dishwasher is a relatively costly component. If you are not experienced with working with electronics, you should not attempt to repair the dishwasher controller yourself. It is advised to seek professional assistance in this situation to avoid doing more harm to the machine.

In the event that the dishwasher control module needs to be repaired, the general course of action will be as follows:

• de-energize the dishwasher;
• open the dishwasher door wide open;
• unscrew the bolts on the ends of the door;
• remove the inner part of the dishwasher door;
• disconnect the wires from the controller, remove the fasteners that fix the board;
• take out the module, ring its triacs with a multimeter;
• after identifying the breakdown, unsolder the damaged semiconductor and install a new one.

A multimeter is required for diagnosis of the control module, while new spare parts and a soldering iron are needed for repair. Replace the damaged semiconductors, reassemble the dishwasher body, and proceed with the test cycle.

It can be quite annoying to deal with a Bosch dishwasher that won’t turn off, but being aware of the typical problems and their fixes can really help. Simple things like the control panel and door latch should be checked first because these are frequently the causes. Don’t forget to try unplugging the dishwasher for a short while and turning it off. Occasionally, a simple reset will fix the issue.

There may be a more complicated issue at hand if these solutions don’t work. There’s a chance that parts like the electronic touchpad or control board are broken. If you think there might be a deeper problem, it’s best to speak with a professional as they have the equipment and knowledge needed to do repairs in a safe and efficient manner.

In the end, minor problems can be avoided by keeping your dishwasher well-maintained and by taking care of them as soon as they arise. You can prolong the life of your Bosch dishwasher by performing diagnostic tests, cleaning filters on a regular basis, and inspecting hoses.
