What F307
actually means.
Milk passes a valve on its way to the central spout, and residue that dries on its stainless bolt can stop it moving. Miele pairs the number with a plain instruction to take the valve out and clean it. The valve should only be removed with the machine off.

What to do when F307 shows on the coffee machineKind of codeMilk system
The milk system could not draw, heat or foam the milk as it should: a tube pinched or not pushed fully onto its connector, a frother or valve clogged with dried milk, a skipped cleaning cycle, or a steam valve and seal that no longer hold. Taking the milk parts apart for a rinse where the manual allows, and running the milk cleaning cycle, clears most of it; steam hissing from the wrong place or a frother that stays cold is a visit.

Restoring the froth: the milk tube, the frother, the air inlet, the milk valve and the cleaning cycle that keeps them clear.
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 F307 on its coffee machines. Follow it to the end: the last card says whether this is a visit.
Switch the coffee machine off; Miele says not to switch it on while the milk valve is out.
Open the door, remove the milk valve and clean it with warm water, without sharp-edged tools that can cut its seal.
Refit the valve, close the door and switch on; if F 307 returns with a clean valve, book a visit.

What not to do
F307 is not a sign that the milk flask is empty or the milk too warm. Hot milk with no froth is a related sign of a blocked valve, but it comes without a number.

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.
