How to fix the i20 error in an Electrolux dishwasher

Electrolux i20 error During operation of an Electrolux dishwasher, problems may arise, such as the self-diagnostic system being activated. This system rarely activates spontaneously as a result of a short-term malfunction; usually, if an error code appears, it means something is wrong with the dishwasher. What should you do if the i20 error appears on the display of your Electrolux dishwasher? Where should you look for the cause of the error, and how can you fix it? These questions require detailed discussion.

Possible reasons for the code to appear

If the i20 code appears randomly on your Electrolux dishwasher, you can try to deactivate it. To do this, turn off the dishwasher, then unplug it after a few seconds. Wait 10 seconds, then turn it back on and run a wash cycle. If the error no longer appears, you are lucky, it is just a control board failure, But if the error appears on the display again and the device stops working, then there really is a problem. What causes this code to appear?

Blockages. The i20 code can be caused by a simple blockage in the waste filter or drain hose. Sometimes, though less commonly, the pump or pressure switch tube can become clogged. You'll need to check all potential locations for such a blockage.
The pump isn't working properly. If the drain pump isn't working properly, this error can be the cause. The impeller or rotor is most likely the cause.

A broken pump is easy to replace yourself, so don't be alarmed in advance.

The pressure switch is clogged or faulty. The i20 code often indicates a faulty or clogged pressure switch. In this case, it should be thoroughly inspected and replaced if necessary.

As you can see, there are only a few possible causes for this error, but they're all unpleasant, so let's roll up our sleeves and try to find the source of the problem. It's best to start with blockages. Electrolux dishwasher parts

We clear blockages

First, you need to clean the debris filter, or at least check it. Open the dishwasher door all the way, pull out the lower rack, remove the lower spray arm, and then unscrew the glass-shaped debris filter. Next to the filter is a mesh strainer; it should be removed and washed along with the filter. A blockage may also form under the mesh strainer at the entrance to the circulation unit; reach in with your fingers and pull out any debris that has accumulated there.

If there was a lot of dirt, you can try restarting the machine and see if the error message persists. Next, check the drain hose. To do this, disconnect the end of the hose from the trap, insert a long piece of wire into it, and twist it. If the wire encounters an obstruction, there's likely a serious blockage in the hose and it needs to be cleared. Remove the hose completely and rinse it with hot water.

The self-diagnostic system itself may hint that the problem is a clog. The i20 error will appear and disappear intermittently.

Checking the pump

To check for a blockage or malfunction of the pump, 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. Disconnect it from the snail housing, taking care to remove the wires, and inspect it. A clogged pump is immediately visible. Either there's a lump of debris clinging to the impeller, or the impeller itself is spinning with difficulty. Clean the pump, then check its resistance with a multimeter. The faulty part needs to be replaced. PMM pressure switch

Checking the pressure switch

Now it's time for the pressure switch. This part can also be accessed through the side of the dishwasher. How can I fix this problem myself?

We disconnect the power wires from the part.
We take it out and check it with a multimeter.
If the resistance is close to zero, the part needs to be replaced; if the resistance is significant, the tube needs to be checked.
We clean the pressure sensor tube and put it back in place, not forgetting to connect the wires.

After all the repairs, the i20 error should disappear. If it persists, you may have overlooked something or didn't check it carefully. You should thoroughly check everything again, and you'll definitely find the cause. If your own troubleshooting isn't successful, or you're simply too lazy to do it, call a mechanic—it's unlikely you'll save any money.

In conclusion, it's worth noting that the cause of the i20 error on an Electrolux dishwasher is relatively easy to find. Even an inexperienced user can spot it 80% of the time. However, other, more complex and ambiguous errors can also occur. If you're interested in more details, read the article.
