Professional Repair Guide

What is this symptom?

Is your AEG dishwasher constantly draining, even when idle or during wash cycles?

Important Tips for Aeg Models

  • AEG dishwashers may display an i30 error when the anti‑flood device detects internal leaks, leading to constant draining; this is specific to the brand’s safety features.

Possible Causes

How to Identify: Dishwasher displays error code i30 or flashes specific LEDs; water may be detected in the base pan

Incorrect drain hose installation causing siphon or backflow

How to Identify: Drain hose installed too low or without correct high loop; continuous draining even when not in washing phase

Part: Drain hose

Clogged or kinked drain hose or drain path

How to Identify: Visible kinks in hose, poor water flow, long drain times or continuous pump activity

Part: Drain hose / drain line

Clogged filters / debris in drain path

How to Identify: Food debris visible in filter, slow drainage before constant draining behavior

Part: Filters / drain inlet

Faulty drain pump or float switch

How to Identify: Unusual noises from pump, pump runs continuously without cycle, float not detecting water level correctly

Part: Drain pump / float switch
