F233 depends on the model: a cup rim sensor issue on built-ins, a central spout assembly issue on countertops.
Model compatibility
Miele reuses codes across series and model years, so F233 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Code
F233
What it means
F233 is a cup rim sensor or central spout assembly fault, depending on the machine type.
What you can check
Countertop owners can pull off the cover and dispensing unit and clean the spouts, then rebuild them tightly. Built-in owners should clean and refit the cup rim sensor, press OK, and check the container and drip tray lid.
When to call a technician
A service visit makes sense if F233 keeps appearing, or if the cup rim sensor is defective and a new one has to be ordered.
Freestanding (countertop) machines
Carefully pull the stainless steel cover forward and off.
Pull the dispensing unit forwards to remove it.
Twist off the upper section with the holder for the milk pipework, and pull off the Y-piece.
Take off the spouts and clean the parts if needed.
Rebuild in the right order, spouts on with the lug facing back and every part tightly connected, then refit the cover.
If the cup rim sensor itself is defective, release it by pressing the two retainers together and press a replacement in from below. Miele customer service is the contact for ordering a new one.
Built-in machines
The cup rim sensor sits under the central spout. Clean it at least weekly, in the dishwasher or by hand with warm water and a little washing-up liquid. If it was bumped or not inserted properly, refit it and press OK. The spout stays at the top until the next switch-on, when detection is reinitialised. Also check that the container is not too far back, has no spoon in it, is tall enough, and does not have a very wide opening. Make sure the drip tray lid is positioned correctly.
Codes that look alike
