Aeg Dishwasher: not starting wash

Professional Repair Guide

What is this symptom?

Is your AEG dishwasher not starting the wash cycle? This common issue can stem from a door not properly latched, an active delay start, or power supply problems. If your display is idle or shows blinking LEDs, follow our guide to troubleshoot and get your dishwasher running again.

Urgency: Medium

Important Tips for Aeg Models

  • Some AirDry models can have misalignment between the door ‘diamond’ element and lock requiring correction for start
  • Delay start or ultraleise/night modes can include long pauses that look like not starting

Possible Causes

Door not properly closed or latched

How to Identify: Dishwasher will not start until a distinct click is heard when closing the door; any obstruction or misalignment prevents full closure. Error lights may flash.

Part: Door latch/closure mechanism

Delay Start or pause function active

How to Identify: Display shows countdown or indicates delay; pressing cancel/reset clears setting and may allow immediate start.

Part: Control panel settings

Power supply issue (socket/circuit)

How to Identify: Dishwasher has no lights or response; other devices also not powered at same socket; circuit breaker may be tripped.

Part: Electrical supply/circuit breaker

Incorrect prior program not ended or options causing long pauses

How to Identify: Program still running or selecting options like Eco/Night that include long pauses, giving impression of not starting; reset might be needed.

Part: Control system/program settings

Housing misalignment affecting door lock engagement (AirDry models)

How to Identify: Door appears closed but latch doesn’t engage because cabinet top is bent; dishwasher won’t start.

Part: Door lock/upper housing alignment
