Error codei40
ApplianceDishwasher
i40 according to the US owner guide
Electrolux owner support in the United States ties i40 to a clogged filter or sump. Food soils have collected there and are in the way.
A note on regional differences
Support material written for other regions gives the same code a different reading, a water level sensing code. The meaning on this entry is the US one.
The step to try
Clean the glass trap and the filter.
Run the dishwasher again.
If i40 remains on the display, contact Electrolux, which means it is time to ask for service.
Codes in the same neighborhood
The filters and sump are also on the check list for i20, where the water did not drain completely. i30 is a leak seen by the anti-flood protection, and i50 is a wash motor or circulation problem.
Electrolux dishwasher service for San Francisco
Should i40 stay after the filter is cleaned, owners in San Francisco and around the Bay Area can phone (415) 449-0036 or look over Electrolux dishwasher repair. Mention that the glass trap and filter were cleaned, together with the code and your model number.
Model compatibility: Electrolux reuses codes across series and model years, so i40 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
