Error code E04 / F27
Appliance Steam Oven
Quick answer

E04 and F27 on Miele steam and combination steam ovens mean the power supply was interrupted.

Model compatibility

Miele reuses codes across series and model years, so E04 / F27 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

Power supply interrupted during a programme or during descaling.

Power to the oven dropped while it was running: that is what F27 and E04 report on Miele steam and combination steam ovens. F27 belongs to ordinary cooking. E04 is the version for an interruption in the middle of descaling.

After a normal programme (F27)

  1. See how far the food has cooked.
  2. If needed, set a new cooking time.
  3. Use Start/Stop to resume.

After descaling (E04)

The time display shows 0:06. Wait for it to count down to zero, then turn the oven off and on once more.

Related codes

  • F04 also describes an interrupted power supply during a programme.
  • E0 is a descaling progress indicator, not an error.
