Important Tips for Aeg Models

  • Some AEG models may have a plastic mesh screen and specific filter designs that should be cleaned regularly; consult the manual for model-specific access.

Possible Causes

Clogged filters or drain area

How to Identify: Visible food debris, grease, or gunk in the dishwasher filter or drain area; water pools after drain cycle; gurgling sounds.

Garbage disposal/air gap blockage (if connected)

How to Identify: Dishwasher drains into a sink disposal with a plugged knockout; air gap cap blocked, preventing flow.

Faulty drain pump

How to Identify: Pump does not run, makes noise, or runs without removing water; multimeter test shows no motor activity.
