Error code F12
Appliance Steam Oven
Quick answer

F12 interrupts the current programme because no water is getting into the steam oven. Check the valve and filter.

Model compatibility

Miele reuses codes across series and model years, so F12 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Water not reaching the oven; current programme interrupted.

F12 appears on a Miele steam oven or combination steam oven when water is not getting in. The cooking programme in progress is interrupted.

Three causes and what to do

  • The water intake valve is not open: open it, then restart operation.
  • The filter in the water intake is blocked: clean the filter.
  • The water inlet hose is faulty: switch the oven off, close the water supply valve and contact Miele Customer Service.

If you cannot clear the fault yourself, switch the oven off and call a plumber or Miele Customer Service.

Related codes

F05 involves the intake valve too, while F11 is about water leaving the steam generator.
