Aeg Dishwasher: not starting

Professional Repair Guide

What is this symptom?

Is your AEG dishwasher not starting despite having power? If pressing the start button doesn't initiate a wash cycle, but the control panel lights are on, it may be due to a stuck program, door lock issues, or power supply problems. Ensure the door is fully closed and check for any obstructions. If the issue persists, consider resetting the control settings or checking the power supply.
