AEG dishwasher i20: drain fault
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
i20 means the dishwasher is not draining normally. Preserve the full display and model, then use whether water remains after one Cancel/Drain command and whether the pump sound starts to choose the next branch before any part or paid repair.
Safety first
Stop and check this first
- Stop immediately for water near electricity, smoke, burning smell, abnormal heat, damaged cable or repeated breaker trips. Close the water tap when a leak is possible; sealed water, heat and mains circuits are professional-only.
Safe checks you can perform
- Capture the decision evidence
- Run the one discriminating check
- Stop at the result boundary

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Evidence-led AEG handoff for i20
What they doA qualified technician should test filter, installation height, drain hose, sink trap, drain pump or control, using the exact model/PNC and the recorded result for whether water remains after one Cancel/Drain command and whether the pump sound starts.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

Capture the decision evidence
No special tools
Procedure
Photograph i20, the complete message and model/PNC. Record the failed programme stage and whether water remains after one Cancel/Drain command and whether the pump sound starts. Do not clear the history repeatedly.
Stop immediately for water near electricity, smoke, burning smell, abnormal heat, damaged cable or repeated breaker trips. Close the water tap when a leak is possible; sealed water, heat and mains circuits are professional-only.

Run the one discriminating check
No special tools
Procedure
Let the water cool. With power isolated, clean the user filter and inspect the visible drain hose and sink trap; do not reach into the pump or probe hidden glass.
Stop immediately for water near electricity, smoke, burning smell, abnormal heat, damaged cable or repeated breaker trips. Close the water tap when a leak is possible; sealed water, heat and mains circuits are professional-only.

Stop at the result boundary
No special tools
Procedure
A blocked sink trap or hose is external. A clean path with no pump sound or unchanged water level selects pump/control service; repeated hot-water draining is not a diagnostic. If the same result returns after this one controlled pass, stop rather than chaining resets or cycles.
Stop immediately for water near electricity, smoke, burning smell, abnormal heat, damaged cable or repeated breaker trips. Close the water tap when a leak is possible; sealed water, heat and mains circuits are professional-only.
