i went to this dishwasher today serial no. 8545 0021 5820,it had been coming up F4 .
when i tried it it filled up with water then there was a repetetive clicking noise coming from the pcb.
i took the door apart then disaster struck, a small white plastic thing about 1″ square by 1/8″ thick with 2 grey wires going to it came away from the door, i cannot see where this thing came from i tried to fit it into the soap dispenser and door lock to no avail. the 2 grey wires go to the pcb where there are the letters KL.
can anybody tell me where this part goes, and what it does and if the machine needs a new pcb.
thanks in advance.
