How to resolve error i20 in an Electrolux dishwasher

error i20 in Electrolux During operation of the Electrolux dishwasher, troubles may arise in the form of the self-diagnosis system triggering. This system rarely just goes off as a result of a momentary glitch; usually, if an error code appears, it means that something is wrong with the dishwasher. What to do if error i20 appears on the display in an Electrolux dishwasher? Where to look for the cause of the error and how to eliminate it? These issues require detailed discussion.

Possible reasons for the code to appear

You can try to deactivate the i20 code that appears randomly on an Electrolux machine. To do this, turn off the machine, and then after a few seconds unplug the power cord from the outlet. Wait 10 seconds and then turn the dishwasher back on and run the wash program. If the error no longer appears, you can say you are lucky, it is just a failure of the control board, but if the error appears on the display again and the equipment stops working, then there really is a problem. Why does this code appear?

Blockages. Code i20 can be caused by a simple blockage in the garbage filter or drain hose. Sometimes, in more rare cases, the pump or pressure switch tube becomes clogged. You will have to check all the places where such a blockage could potentially form.
The pump is not working well. If the drain pump does not perform its function well, it may cause the indicated error. The reason most likely lies in the impeller or rotor.

It's easy to replace a broken pump yourself, so don't be alarmed in advance.

The pressure switch is clogged or faulty.Often the appearance of code i20 indicates a breakdown or clogging of this part. In such a situation, you will have to check it carefully and, if necessary, replace it.

Removing blockages

First of all, you need to clean the garbage filter, or at least check it. Open the dishwasher door all the way, pull out the lower basket, remove the lower spray arm, and then unscrew the glass-shaped garbage filter. There is a mesh next to the filter; it needs to be pulled out and washed along with the filter. A blockage may also form under the mesh at the entrance to the circulation block; reach there with your fingers and pull out everything that has accumulated there.

If there was a lot of dirt, you can try to restart the machine and check whether the error “pops up”. Next you need to check the drain hose. To do this, disconnect its end from the siphon, insert a long wire there and twist it. If the wire encounters an obstacle, there is most likely a serious blockage in the hose and needs to be cleaned. We completely remove the hose and rinse it with hot water.

The self-diagnosis system itself may hint that the problem is a blockage. Error i20 will appear and disappear.

Checking the pump

To check for a blockage in the pump or a malfunction, you need to remove the right side wall of the Electrolux dishwasher. The pump will be visible in the space between the wall of the tray and the body of the washing chamber. We disconnect it from the cochlea body, not forgetting about the wires, and inspect it. A clogged pump is immediately visible. Either there is a lump of rags hanging on the impeller, or the impeller itself is difficult to rotate.Clean the pump and then check its resistance with a multimeter. The faulty part must be replaced. pressure switch PMM

Checking the pressure switch

Now it’s the turn of the pressure switch. This part can also be reached through the side wall of the dishwasher. How can I fix the problem myself?

Disconnect the power wires from the part.
We take it out and check it with a multimeter.
If the resistance is close to zero, you need to change the part; if the resistance is significant, then you need to check the tube.
We clean the pressure tube and put it in place, not forgetting to connect the wires.

After all repair work, error i20 should disappear. If it remains, it means you didn’t check something carefully or missed something. You need to check everything carefully again and you will definitely find the reason. In the event that your independent searches are not successful or you are simply too lazy to carry them out, call the specialist, it seems that you will not be able to save money.

In conclusion, we note that the cause of the i20 error on an Electrolux dishwasher is relatively easy to find. Even an ordinary person without experience succeeds in this in 80% of cases.
