Error code F12
Appliance Steam Oven
Quick answer

F12 stops the programme as no water enters the oven. The valve, the intake filter and the inlet hose are the places named.

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.

No water arriving, and a programme that stops half way: that is F12 on a steam oven or combination steam oven from Miele.

Code F12
What it means Water not reaching the oven; current programme interrupted.
What you can check Make sure the water intake valve is open, then start again. If the filter in the water intake is blocked, clean it.
When to call a technician If neither step helps, suspect the inlet hose: turn the oven off, close the water supply valve and arrange a service visit. A plumber can also help with the supply.

Work through these

  1. Make sure the water intake valve is open, then start again.
  2. Clean the filter in the water intake if it is blocked.
  3. Suspect the inlet hose when neither helps. Turn the oven off, shut the water supply valve and get in touch with Miele Customer Service.

Cannot fix it yourself? Power the oven down and ask a plumber or Miele Customer Service for help.

Nearby codes

  • F13: oven compartment temperature too high.
  • F14: too little water in the steam generator.
