Error code F18
Appliance Dishwasher
Quick answer

F18 on a Miele dishwasher is a defective water intake valve. Switch off, close the stopcock and call Miele Customer Service.

Model compatibility

Miele reuses codes across series and model years, so F18 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

Defective water intake valve; technical fault.

F18 on a Miele dishwasher means the water intake valve is defective. Miele calls it a technical fault that you cannot remedy yourself.

Steps from the operating instructions

  1. Switch the dishwasher off.
  2. Close the stopcock.
  3. Call Miele Customer Service.

Do not confuse it with a blocked inlet. For that, F13 and F173 cover restricted water supply, while F19 is a flow meter fault.
