Is it definately over filling and not just leaking from a warped door seal?

Looks like it’s a timed-fill machine. Fill is set initially by the float tripping and the machine then pumping a fixed amount of water back out. The computer the calculates how long to fill before the float trips.

1/ Did you fit the correct Bosch inlet valve – flow rate is critical?
2/ Is the float free to move, is it the right way up if you’ve removed it for cleaning?

Otherwise, the only control is the pcb. I think there’s a mod – one of the BSH lads may be able to advise on that one.

Its not door seal ,when you open door the water is just below lip
