Electrolux Dishwasher Error Code i20
Drain error
Common Causes
- 1Clogged triple-filter
- 2Blocked or looped drain hose
- 3Drain pump impeller jammed
- 4Check valve stuck from grease
Step-by-Step Troubleshooting
- 1
Remove and clean the triple-filter system at the tub bottom, separating the coarse and fine screens
- 2
Check the drain hose at the disposal or air-gap connection for a food blockage or a fresh-install knockout plug left in place
- 3
Verify a proper high-loop or air-gap so dirty sink water cannot siphon back and re-trigger i20
- 4
Listen for the drain pump hum at the drain step — no sound at all points to a seized motor, a hum without flow points to a jammed impeller
- 5
Clear the drain check valve of congealed grease, which lets water dribble back and stretch the drain past its timeout
Pro Diagnostic Tip
i20 is a "did not drain in time" fault on the Electrolux flow-through platform, and its alias i40 is the very same fault after a second timeout — if the two alternate, suspect an intermittent blockage in the drain check valve rather than a dead pump. Because these dishwashers share a small drain pump with a delicate impeller, a single shard of glass or a fruit sticker is enough to slow the drain into i20 without stopping it entirely; always inspect the sump before condemning the pump.
