Important Tips for Miele Models

  • Miele models may have heat exchangers or filters specific to condenser/heat pump models that need periodic cleaning beyond the lint trap

Possible Causes

Clogged lint filter

How to Identify: Drying times are long and lint accumulates visibly on the filter screen; cleaning the filter improves drying performance

Blocked exhaust vent/ventilation system

How to Identify: Reduced airflow at external vent opening and extended drying times; visible lint or debris at vent hood

Part: Exhaust vent/duct

Overloading the dryer

How to Identify: Dryer struggling with large or mixed heavy loads; clothes remain damp in center of load

Part: Drum/airflow

Faulty heating element or poor heat generation

How to Identify: Dryer tumbles but there’s minimal heat and clothes stay wet; may require multimeter testing

Part: Heating element

Malfunctioning moisture sensor

How to Identify: Drying cycles extend or end prematurely despite clothes being damp or dry; sensors may have residue

Part: Moisture sensor
