What F233
actually means.
The central spout lowers itself until a sensor touches the rim of your cup. If something bumps that sensor while the spout is rising, it loses track of where it is, and F233 appears. Until the next switch-on the spout stays up and cup-rim detection is off.

What to do when F233 shows on the coffee machineKind of codeControl board and power
The electronics that read the keys and run the grinder, the pump and the heater have flagged a problem with themselves or with the power reaching them: a supply that dipped or spiked, a board that lost its settings after an outage, a display or touch panel that stopped answering, or a relay that stuck. One switch-off at the key or the breaker clears a passing glitch; a message that returns, or any hot smell, means the power stays off and a technician tests the board.

Shows up asWhat a Coffee Machine Error Code or Warning Symbol Means
A coffee machine error code may show as a short string of letters and numbers, a flashing symbol for water, grounds or the brew unit, a short sentence on a text display, or a machine that stops with one light blinking.

Before you book,
in this order.
Each step comes from Miele's own guidance for F233 on its coffee machines. Follow it to the end: the last card says whether this is a visit.
Confirm the message with OK.
Refit the cup-rim sensor under the central spout so it sits in place.
Switch the machine off and back on later; detection resets at the next switch-on, and if F233 keeps returning with the sensor seated, book a visit.

What not to do
F233 does not mean the spout motor has failed. It is also different from a drink stopping early with a very wide cup, which Miele treats as normal because the sensor cannot touch the rim.

Built-in coffee system
The coffee machine set flush into a tall kitchen cabinet, filled from a water tank behind its front, grinding beans and brewing each cup on its own before sliding out on rails for service.
Plumbed coffee system
The built-in coffee machine connected to the house water supply, filling itself through an inlet valve and sometimes draining its rinse water to a line of its own, so nobody ever lifts out a tank.
Countertop espresso machine
The fully automatic bean-to-cup machine that stands on the counter, grinding, tamping, brewing and frothing at the touch of a key, with its tank, hopper and grounds drawer all reached from the top and the front.
In Miele's own words
The cup-rim sensor is not inserted or is incorrectly inserted.

Still showing F233?
Three things make the booking useful: the message or number exactly as the display showed it, the full model number from the plate, and whether the machine still grinds and pours at all. Send those and the likely part can be looked up before the van leaves.
