Error E01 on a Beko dishwasher

Taking too long to fill the dishwasher indicates that something is wrong with the appliance. Usually after this, error E01 appears, caused by water overflow. At the same time, overflow does not always cause external leakage, because this situation is possible if the user accidentally opens the door of the washing chamber during the operating cycle. Let's figure out how to accurately determine overflow, as well as how to deal with it in a timely manner.

The most common problems causing E01

Overflowing water does not guarantee that something is broken in your Beko dishwasher. It is quite possible that the reason is something else, which can be easily fixed with your own hands.

• Garbage filters are clogged. These filter elements are located at the bottom of the PMM washing chamber. During operation of the device, they can become clogged with food debris, bones, napkins, glass fragments and other foreign objects. It is because of the blockage that water sometimes cannot pass through the filters, which can be corrected by thoroughly cleaning the filter elements.
• Increased pressure in the water supply. Because of this, the flow sensor will not work correctly, because it will not have time to open the reed switch, so the Beko dishwasher will fill in too much liquid. You can fix the problem by formally contacting the company that is responsible for the water supply in your area, or you can slightly close the water supply shut-off valve to reduce the pressure.
• Short-term failure of the PMM control module. Another reason for error E01 is a one-time failure of the control board, which could have mistakenly filled in too much liquid.In this case, you need to reset the current cycle to reset the control board. To do this, you need to unplug the household appliances for about 15 minutes, and then try to start the sink again. If after these manipulations everything is in order, then the reason was a one-time failure, otherwise you will have to call a service center specialist.

In any of the described cases, it is necessary not only to eliminate the malfunction, but also to remove all water from the pan. This is necessary so that the Aquastop protection does not work again, starting the drain pump.

The water supply valve is “moody”

The error code could also appear due to the fact that the fill valve, consisting of an electromagnetic coil and a membrane, has failed. If the dishwasher If Beko has filled in too much water, the specified membrane may stop functioning normally, which sometimes becomes deformed and even breaks into pieces, which is why it stops blocking the flow of water.

If this happens, water will continuously flow into the machine, even if the fill valve is locked in the closed position.

The membrane very often fails due to the fact that the equipment was left in an unheated room for the winter - in this case, the remaining water in the valve freezes and damages the membrane.

If the cause of the malfunction is really in the fill valve, then the housewife will notice this not only because the Beko PMM began to take in too much water, but also by the overflow through the door or drainage hoses into the pan. After this, the Aquastop system will work, causing additional problems. It is very difficult to restore the valve; it is much easier to buy a new one.

The pressure switch is not functioning

Another error E01 may begin to haunt the user due to a damaged pressure switch.This water level sensor is necessary in the system in order to correctly record the amount of liquid collected and transmit accurate information to the control module of the Beko dishwasher. If it fails, then the machine will not be able to determine the moment when it is necessary to stop the water supply. Most often, one or several parts of the pressure switch break down:

• the sensor tube, which could fall out of its seat, become clogged, or fail due to strong vibrations of the dishwasher;
• a pressure sampling chamber, which is negatively affected by impurities of low-quality tap water, food residues, and undissolved household chemicals. All of the above can clog the camera;
• the sensor coil could also fail due to a sudden voltage drop.

What can I do to quickly fix the problem? It is necessary to disconnect the Beko dishwasher from all communications, provide free access to the equipment, remove the tray, find the water level sensor, carefully remove it and check it with a multimeter. Additionally, you can blow out its tube, from which clearly audible clicks should be heard. If the element is faulty, it must be replaced.

The flowmeter is broken

Another common cause of error E01 is the water flow sensor, which helps the water level sensor record the current amount of liquid. If the part is jammed, it will not be able to accurately determine the water level, so the liquid supply will not finish on time.

Like many other key components of a Beko dishwasher, the flowmeter cannot be repaired, it can only be replaced with a new element. Take the damaged sensor to the store as an example to buy a suitable PMM spare part.

The control board is not working correctly

The most unpleasant option is failure of the control board. Electronics is the most complex component of technology, because it is a kind of “brain” of the entire system, responsible for the performance of all key components.

The control module is very complex, and its restoration requires special equipment, so it is better not to try to repair it yourself, or to install new software on it yourself. It’s better to entrust the work to a technician who can replace the firmware within an hour if that’s the problem. Typically this work costs about $25, but the price may vary depending on the region.
