Overview

Error code F05
Appliance Steam Oven
Quick answer

F05 comes from an intake valve that is not fully open or a nozzle that is scaled or blocked. The manual lists valve and nozzle steps.

Model compatibility

Miele reuses codes across series and model years, so F05 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 intake valve not fully open, or water nozzle scaled or clogged.

Two things lie behind an F05 message on a steam oven or combination steam oven from Miele. Either the water intake valve has not been opened all the way, or the water nozzle is carrying scale or is clogged.

At a glance

Code F05
What it means Water intake valve not fully open, or water nozzle scaled or clogged.
What you can check Open the water intake valve fully and run the oven again. If F05 returns, descale the water nozzle with the oven cool, wearing oven gloves and watching for steam.
When to call a technician Call a technician if F05 stays after the valve is fully open and the nozzle has been descaled and refitted as described.

Where to start

  • Turn the water intake valve to fully open.
  • Run the oven again.

Cleaning the nozzle

An F05 that comes back means the nozzle needs descaling. Watch out for hot surfaces and steam; open the door slowly and use oven gloves.

  1. Let several buzzer tones sound before touching anything.
  2. Take the food out. Keep the door open and let the cavity cool.
  3. Lift out the side runners, then draw the nozzle out.
  4. Treat it with Miele system descaling agent or another suitable descaler, and rinse under the tap afterwards.
  5. Flush the water-carrying parts before refitting: door shut, power on, Steam cooking mode, 100 °C, a duration of 1 minute, then Start/Stop.
  6. When cooling down is done, open up and put the nozzle and runners back.

Normal use can resume afterwards.
