Model compatibility: Electrolux reuses codes across series and control generations, so i20 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
Electrolux dishwasher code i20 points to drain restriction or incomplete draining detected. The display narrows the diagnostic path, but it does not prove which component should be replaced. Use the observed symptoms and the full model number to confirm the correct diagnostic path.
The code identifies a diagnostic condition, not a guaranteed failed component: drain restriction or incomplete draining detected. The visible behavior matters: water may remain in the tub can occur with clogged filters or sump, but restricted or pinched drain hose remains another documented possibility.
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 i20 remains after the external drain path and filters are clear.
A returning i20 should be diagnosed with the model-specific service path. Tell the technician whether water may remain in the tub; that observation can help prioritize clogged filters or sump.

It indicates drain restriction or incomplete draining 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.
