Error codeEr04 drying damper
ApplianceDishwasher
Quick answer
Er04 on an Electrolux built-in dishwasher means: drying damper not operating. It is listed for the EIDW6105 and EIDW6305.
Model compatibility: Electrolux reuses codes across series and model years, so Er04 drying damper may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Drying damper not operating.
An Electrolux dishwasher that shows Er04 is reporting that the drying damper is not operating.
About the Er04 code
The entry comes from guide 154671201 for the EIDW6105/EIDW6305 built-in dishwashers. It is the EIDW6305 whose status window shows codes, per the manual. The series is a legacy one, not a current model line.
Do not open the dishwasher while it is plugged in. Finding the cause is work for a technician.
Neighbouring entries
If the display does not match, compare Er05 (upper fan speed feedback in the dry cycle); Er06 (lower fan speed feedback in the dry cycle); Er03 (wash pump not operating).
