Fault F233 appears on the coffee machine display (built-in coffee machine).
The cup rim sensor is located under the central spout. Clean the cup rim sensor at least once a week and more often if heavily soiled.
Proceed as follows to clean the cup rim sensor:
Press the two retainers together, see figure. The cup rim sensor is released.
Clean the cup rim sensor in the dishwasher or by hand using warm water and a little washing-up liquid.
To refit the cup rim sensor, press it into the holder on the central spout from below.
If the central spout is moving upwards and the cup rim sensor is bumped, e.g. with a cup, the cup rim sensor loses its reference position.
Fit the cup rim sensor correctly.
Press the OK button to acknowledge the message.
Refit the cup rim sensor.
Cup rim detection remains inactive and the central spout stays in the top position until the coffee machine is next switched on. Cup rim detection is reinitialised during the next switch-on operation.
Position the container so that the sensor can detect the rim.
Use a different container or position the existing one so that the sensor can detect the rim.
Position a container that is tall enough and does not have a spoon in it so that the container is touching the cup rim sensor.
Use a taller container.
Assemble the drip tray correctly.
Slide the lid under the lug next to the contacts and apply pressure to the lid until the catches at the sides audibly click into place, see figure.
Insert the milk pipework correctly.
The angular moulded hose and the longer milk pipework are connected. Start by attaching the angular moulded hose to the top of the central spout. The black connecting piece should be pointing to the rear .
Connect the bottom end of the moulded hose to the dispensing unit .
Insert the milk pipework into the milk valve on the left and right-hand sides and . Push the connecting pieces into the silicone seal as far as they will go.
Check that the milk pipework is snug against the housing and that the cover can be easily attached.
If necessary, turn the milk pipework towards the back at the connecting piece on the right-hand side of the milk valve.
Insert the central spout cover correctly.
Press the central spout up slightly.
If the central spout can be moved up, this means the spout is not clipped into place.
Take hold of the central spout at the side and pull the spout down with force.
The central spout audibly clips back into place. The emergency release is revoked.
