How to fix Miele F78

Free the pump with warm water
Take out the lower spray arm and filter. Pour about 1 quart (1 liter) of warm water, 167°F (75°C) at most, with 3 to 5 drops of rinse aid into the cabinet. Wait 5 minutes, refit the parts and run the program. Repeat up to 3 times.
Restart the program
Turn it off, wait a few seconds, turn it back on, pick the program and press Start/Stop.

When to call a technician

If F78 is still there after a couple of soaks, book a Miele technician.
