Miele F15 points at the hot water inlet. The manual covers the stopcock, the inlet filter and supply pressure.
Model compatibility
Miele reuses codes across series and model years, so F15 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What it means
F15 means the hot water inlet is blocked or restricted.
What you can check
Start with the hot water tap: if it was left shut, open it and restart the wash. If it is open, turn it off, take the hose off, and clean the small plastic inlet filter, then refit it and check for drips.
When to call a technician
Call a technician if the filter is clean and the tap is open but the code stays, or if the hot water flow is weaker than about 5 liters in 15 seconds with the tap fully open and a plumber cannot raise it.
Cause 1: stopcock still shut
End the wash programme, open the hot water stopcock, choose the programme and start again.
Cause 2: dirty inlet filter
Shut the hot water stopcock first. Then:
Take the inlet hose off the stopcock.
Lift the rubber seal (1) out of its recess.
Turn the free hose end upside down; the plastic filter (2) drops out.
Wash the filter and never forget to refit it.
Put everything back in reverse order, open the stopcock and confirm there are no drips. If there are, tighten the connection.
Cause 3: low supply pressure
The benchmark is at least 5 l from the fully open stopcock in 15 s. Below that, contact the facility manager or a plumber. If pressure is too low and cannot be increased, Miele Customer Service is the contact named.
