Error codei40
ApplianceDishwasher
Affected model seriesEI24ID50Q family
Quick answer
Electrolux dishwasher code i40 indicates filter or sump restriction detected.
Model compatibility: Electrolux reuses codes across series and control generations, so i40 may mean something different on another appliance or platform. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
When i40 appears on your Electrolux dishwasher, it indicates filter or sump restriction detected. Model and control-platform context matters before any part is condemned. Use the observed symptoms and the full model number to confirm the correct diagnostic path.
Read this display narrowly on the documented control platform: filter or sump restriction detected. When water may remain in the tub, the code helps separate an external condition from possibilities such as clogged filters or sump and restricted or pinched drain hose.
This code is documented for Electrolux dishwasher platforms including the EI24ID50Q family. Confirm the exact model before applying service-level diagnostics.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Clean the removable filters and accessible sump area.
Check the drain hose for kinks or crushing.
If connected to a disposer, confirm the knockout plug was removed.
Run one cancel/drain cycle after correcting an external restriction.
Important safety warning. Stop if water is leaking onto the floor or the dishwasher repeatedly refills and drains abnormally.

When to call a technician
Book service if i40 remains after the external drain path and filters are clear.
If i40 returns, give the technician the exact model number, the code exactly as shown, and whether water may remain in the tub. That information helps focus testing on clogged filters or sump and related platform-specific circuits.

It indicates filter or sump restriction detected. Confirm the full model number because Electrolux diagnostic meanings can vary between control platforms.
You can try the safe external checks on this page and one power reset when appropriate. If the code returns, repeated resets are not a substitute for diagnosis.
Avoid repeated wash cycles while water remains in the tub. Correct accessible drain restrictions first and test one cancel/drain cycle.
