Error E20 on the display of the Electrolux washing machine: what does it mean and how to fix it?

One of the most common mistakes made by Electrolux brand washing machines is E20. It is highlighted if the process of draining the waste water is disturbed.

In our article we will try to figure out why such a malfunction occurs and how to fix the malfunction on our own.

Many current washing machines have a self-monitoring option, which is why, if any interruptions in the operation of the unit occur, information with an error code is immediately displayed on the display, it can also be accompanied by a sound signal. If the system issues E20, then you are dealing with the problem of the drain system.

It means that the unit either cannot completely remove the used water and, accordingly, is not able to spin things, or the water comes out too slowly - this, in turn, leads to the fact that the electronic module does not receive a signal about an empty tank, and this causes the system to freeze. The parameters of draining water in the washing machine are monitored by a pressure switch, some models are additionally equipped with the "Aquastop" option, which informs about such problems.

Often, the presence of a problem can be understood without decoding the information code. For example, if a puddle of used water has formed near and under the car, it is obvious that there is a leak.

However, the situation is not always so obvious - water may not flow out of the machine or an error appears at the very beginning of the cycle. In this case, the breakdown is most likely associated with a malfunction of the sensors and a violation of the integrity of the elements connecting them with the machine control unit.

If the pressure switch detects deviations in operation several times in a row for several minutes, then it immediately switches on the water drain - thus it protects the control unit from overload, which can cause more serious damage to the parts of the washing machine.

If you find an error, the first thing to do is disconnect it from the power supply and only then carry out an inspection in order to identify the cause of the malfunction. The most vulnerable points of the unit are the drain hose, the area of ​​its attachment to the sewer or the washing machine itself, the drain hose filter, the seal, as well as the hose that connects the drum to the detergent compartment.

Less often, but the problem can still be the result of cracks in the case or in the drum. It is unlikely that you will be able to fix such a problem on your own - most often you have to contact the wizard.

There are other reasons for the E20 error.

This is a special sensor that informs the electronic module about the degree of filling the tank with water. Its violation can be caused by:

• damaged contacts due to their mechanical wear;
• the formation of a mud plug in the hose connecting the sensor to the pump, which appears due to the ingress of coins, small toys, rubber bands and other objects into the system, as well as with prolonged accumulation of scale;
• oxidation of contacts- usually occurs when the machine is operated in damp and poorly ventilated areas.

Failure of the branch pipe can be due to several reasons:

• using too hard water or low quality washing powders - this causes the appearance of scale on the inner walls of the unit, over time the inlet narrows noticeably and the waste water cannot drain at the required speed;
• the junction of the branch pipe and the drain chamber has a very large diameter, but if a sock, bag or other similar object gets into it, it can become clogged and obstruct the drainage of water;
• the error is often displayed when the float is stuck, warning about the ingress of undissolved powder into the system.

This part breaks down quite often, the violation of its functionality can be caused by a number of reasons:

• if the drain system is equipped with special filter that prevents foreign objects from escaping, when they accumulate, stagnation of water occurs;
• small things may cause interruptions in the operation of the pump impeller;
• the work of the latter may be disrupted due to the accumulation of a significant amount of limescale;
• drift jam occurs either due to its overheating, or due to a violation of the integrity of its winding.

The control module of the unit of the considered brand has a rather complex structure, it is in it that the entire program of the device and its errors is laid. The part includes the main process and additional electronic components. The reason for the interruption in its work may be moisture penetrated inside or power surges.

In some cases, a malfunction with code E20 can be eliminated on its own, but only if the cause is correctly determined.

Finding out where the pump is located in an Electrolux washing machine is not so easy - access is possible only from the back. To do this, you need to perform the following sequence of actions:

• open the rear screws;
• remove the cover;
• carefully disconnect all wires between the pump and the control unit;
• unscrew the bolt located at the very bottom of the CM - it is he who is responsible for holding the pump;
• pull out the clamps from the pipe and pump;
• remove the pump;
• carefully remove the pump and wash it;
• additionally, you can check its resistance on the winding.

If a positive result is not achieved - therefore, the problem lies elsewhere.

Before you start cleaning the filters, you must drain all the liquid from the washing machine, for this use the emergency drain hose. If there is none, you will need to unscrew the filter and bend the unit over a basin or other large container, in which case the drain is done much faster.

To eliminate blockages in other parts of the drainage mechanism, you must perform the following steps:

• check the function of the drain hose, for which it is separated from the pump, and then washed with a strong pressure of water;
• check pressure switch - for cleaning it is blown with a strong air pressure;
• if the nozzle is clogged, then it will be possible to remove the accumulated dirt only after the complete disassembly of the machine.

In order to determine the cause of the appearance of the error in question in Electrolux machines, you need to be extremely careful. It is very important to make a gradual inspection, the filter should be subjected to an initial inspection. The machine should be inspected every 2 years, and the filters should be cleaned at least once a quarter. If you have not cleaned it for more than 2 years, then disassembling the entire unit will be a pointless step.

The occurrence of error E20 can be avoided by using water softeners during the washing process, as well as specialized bags for washing - they will prevent clogging of the drain system.

By following the instructions listed, you can always carry out all the repair work on your own.
