Miele Dryer: not drying properly

Professional Repair Guide

What is this symptom?

Experiencing issues with your Miele dryer not drying properly? Clothes may remain damp or only partially dry after a full cycle. This common problem often arises from restricted airflow due to lint buildup, a faulty moisture sensor, or heating element failures, particularly in Miele heat pump and conventional dryers.

Urgency: Medium

Important Tips for Miele Models

  • Miele heat pump dryers can accumulate lint in internal heat exchangers and filters specific to model type

Possible Causes

Restricted airflow due to lint filter or vent blockage

How to Identify: Clothes still damp after cycle; reduced airflow at external vent; dryer gets hot but moisture cannot escape

Part: Lint filter and external vent/duct

Faulty moisture sensor

How to Identify: Dryer stops too early leaving clothes damp despite heat; inconsistent drying performance

Part: Moisture sensing strips/sensors

Heating element or thermostat failure

How to Identify: Dryer fails to reach correct temperature; clothes damp and air not hot

Part: Heating element, thermostat/thermal fuse
