miele g646sc no heat.

called out to this dishwasher, it had leaked into the base because the thermister had worked its way out of its grommett. refitted, dried out and checked for leaks, all seemed ok. customer phones two days later and says it goes all through the program but does not heat. took another look, all the heating circuit appears to be ok. would the program carry on if it did not reach temperature! the only thing i can think of is that the thermister thinks its already up to temp. any other thoughts would be great as i dont want to go back with a new thermister if its not going to cure the fault.
cheers.

heater and stats check out ok, relay coil has circuit, contacts look a bit black but ok i think.

Pressure switch not pulling in heater relay? just a shot in the dark if everything else is metering out ok.
