AEG and Electrolux dishwasher error code i20

Parts: amzn.to/3ghayfi
Check your dishwasher filter and sump are clean.
If an i20 error code suddenly appears on the screen of an Electrolux dishwasher, try resetting the сode. To do this, switch off the appliance and, after a few seconds, disconnect the mains plug from the socket. Wait 10 seconds and then switch on the dishwasher and start the washing programme. If the error code no longer appears, you are lucky!
If the error code appears again, the drain pump is probably blocked.
You can use my instructions to correct the error, but always disconnect the mains plug before starting the repair.
