Water Leak Detected (Aquastop)

What it means

This code appears on Electrolux (and AEG) front-load washing machines when the Aquastop leak protection system detects water in the base or a leak in the water path, so the washer stops the water supply and may run the drain pump. The meaning should be confirmed for your model, and the same number can mean something else on other brands.

Models covered: Electrolux (and AEG) front-load washing machines; the code shows on the display or as blinking lights. Sub-codes (e.g. E11, E21) belong to the same family.
