I have had 2 of these in the last couple of days where the machine seems to have a mind of its own. Sometimes it will end after 10-15 minutes other times it will say it has ended then leave the machine with warm clean water in after it has been on for about 1 hour then next time maybe 30 minutes. ❓
I have changed the pcb on Bosch’s advice and still no luck, open to ideas please.
