Error E01 on a Beko dishwasher

A dishwasher that takes too long to fill with water indicates a problem. This is usually followed by an E01 error, caused by an overflow. However, an overflow doesn't always cause an external leak; it can also occur if the user accidentally opens the door during the wash cycle. Let's look at how to accurately identify an overflow and how to deal with it promptly.

The most common problems that cause E01

An overflow doesn't necessarily mean there's something wrong with your Beko dishwasher. It's quite possible that something else is at fault, something that can be easily fixed yourself.

• The debris filters are clogged. These filter elements are located at the bottom of the dishwasher's wash chamber. During use, they can become clogged with food debris, bones, napkins, glass fragments, and other foreign objects. This clogged filter can sometimes prevent water from passing through the filters, which can be remedied by thoroughly cleaning the filter elements.
• High water pressure. This will cause the flow sensor to malfunction because it won't open the reed switch fast enough, causing the Beko dishwasher to overfill. This can be resolved by contacting your local water company, or by slightly closing the water supply valve to reduce the pressure.
• A temporary malfunction of the dishwasher's control module. Another cause of the E01 error is a one-time malfunction of the control board, which may have mistakenly filled with too much liquid. In this case, you need to reset the current cycle to reset the control board. To do this, unplug the dishwasher for about 15 minutes, then try restarting the dishwasher. If everything returns to normal after this, then the problem was a one-time malfunction; otherwise, you'll need to call a service technician.

In any of the above cases, it's necessary not only to fix the problem but also to drain all water from the tray. This is necessary to prevent the Aquastop protection from being triggered again, triggering the drain pump.

The water supply valve is "moping"

The error code could also appear due to a faulty inlet valve, which consists of an electromagnetic coil and a membrane. If the dishwasher If Beko has been overfilled with water, the membrane may stop functioning properly, sometimes becoming deformed or even breaking apart, causing it to no longer shut off the water flow.

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

The membrane often fails because the equipment was left in an unheated room over the winter – in this case, the remaining water in the valve freezes and damages the membrane.

If the inlet valve is indeed the cause of the problem, the housewife will notice not only that the Beko dishwasher is filling with too much water, but also that water is overflowing through the door or drain hoses into the tray. This will trigger the Aquastop system, causing further problems. Repairing the valve is very difficult; it's much easier to buy a new one.

The pressure switch is not functioning

Another possible cause of the E01 error is a faulty pressure switch. This water level sensor is essential to accurately record the amount of liquid drawn in and transmit accurate information to the Beko dishwasher's control module. If it fails, the machine will be unable to determine when to stop the water supply. Most often, one or more parts of the pressure switch fail:

• the sensor tube, which could have come loose from its seat, become clogged, or failed due to strong vibrations of the dishwasher;
• The pressure chamber, which is negatively affected by impurities from poor-quality tap water, food residue, and undissolved household chemicals. All of these can clog the chamber;
• The sensor coil could also fail due to a sudden voltage surge.

What can I do to quickly fix the problem? Disconnect the Beko dishwasher from all power supplies, ensure easy access to the appliance, remove the tray, locate the water level sensor, carefully remove it, and check it with a multimeter. You can also blow out its tube; you should hear a clearly audible clicking sound. If the element is faulty, it needs to be replaced.

The flowmeter is broken

Another common cause of the E01 error 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 intake will not finish in time.

Like many other key components of a Beko dishwasher, the flow meter cannot be repaired; it can only be replaced with a new element. Take the damaged sensor to the store as an example to purchase a suitable replacement part.

The control board is not working properly

The most serious scenario is a control board failure. The electronics are the most complex component of the device, as they are the "brain" of the entire system, responsible for the operation of all key components.

The control module is very complex and requires specialized equipment to repair, so it's best not to attempt repairs or install new software yourself. It's best to entrust the job to a technician who can replace the firmware within an hour if that's the problem. This typically costs around $25, but the price may vary depending on your region.
