Drain Problem

What it means

This code appears on Electrolux (and AEG) dishwashers, shown on the display as i20, and means water was not drained from the unit within the set time. The program stops with water left in the bottom, most often because of blocked filters or a kinked drain hose. The same number can mean something else on other brands.

Models covered: Electrolux (and AEG) dishwashers; the code shows as i plus two digits (e.g. i10).
