The AEG E20 (or E21) fault code is typical of older AEG washers. The E20 code signals slow draining.
The E20 – E21 codes mean that the draining has stopped.
How to solve it
This is quite common with AEG washing machines. Most likely, there is a blockage in the system, or one of its components has gone faulty.
- Check the drain filter for clogs. There may be hair, lime, goo, etc.
- Check all pipes and hoses for clogs.
If the code is still there, there may be a problem in the drain pump or control board. Please, apply to our technical maintenance service and fill out the repair form. Most likely, a technician will arrive within two days.
