Before you book,
in this order.
Each step comes from Miele's own guidance for F78 on its dishwashers. Follow it to the end: the last card says whether this is a visit.
Take out the lower spray arm and the filters, making sure the filter combination goes back flat.
Put a liter of warm water, at most 165°F, plus a few drops of rinse aid into the tub and wait 5 minutes.
Restart and repeat the soak two or three times, then switch off, wait a few seconds and switch back on.
Book a visit if F78 persists after the soaks.
Still there?
It usually turns into wash motor and circulation. Book with the code and the model number.
What not to do
F78 is not a drain code, even though the soak goes into the bottom of the tub.
