What does the AEG i20 error code mean?
i20 is AEG’s drainage fault code for dishwashers. The machine cannot pump the waste water out within the required time. This is most commonly caused by a blocked filter, a jammed pump impeller, or an obstruction in the drain hose.
🔍 Symptoms
- Water remaining in the bottom of the dishwasher
- Machine stops at the drain phase
- Drain pump audible but no water is expelled
- Dishes dirty and wet after a completed cycle
- Error appears at the end of every wash
How to fix the AEG i20 error code
- Clean the filter assembly thoroughly.
- Remove standing water and inspect the pump impeller for debris.
- Check the drain hose for kinks.
- Check the connection to the kitchen sink waste pipe.
- Test or replace the drain pump motor if the above steps do not resolve the issue.
Frequently Asked Questions (FAQ)
Q: Where is the drain pump on an AEG dishwasher?
A: The drain pump is located beneath the filter assembly in the sump area at the base of the tub. Remove the filter to access the pump cover, which usually opens with a quarter-turn.
Q: Can an AEG dishwasher drain pump be cleaned rather than replaced?
A: If the impeller is simply blocked by debris, cleaning it is sufficient. If the motor windings have burned out, the entire pump assembly must be replaced.
Q: My AEG shows i20 only occasionally — is it worth investigating?
A: Yes. Intermittent i20 errors usually indicate a partial blockage that will worsen over time and eventually cause a full drain failure. Clean the filter and check the pump proactively.
