What Does Error F20 Mean?

The Miele washing machine error F20 indicates a heating or temperature fault, specifically that the Thermostop function has been activated because the set temperature wasn't reached in time. This can cause the machine to pause during a wash cycle, with the display showing 'F20' until the correct temperature is attained. If the error persists after a basic reset, further inspection of the heating system and temperature sensors is essential.

Common Symptoms:

  • F20 appears during a wash cycle
  • Machine may pause as Thermostop function engages (time display pauses) before resuming when temperature reached (per official guidance)
  • Error persists on restart

Possible Causes

  • Thermostop function triggered / heating circuit fault (high)
  • Water fill/level issue or pump filter/drain interference (low)
