AEG Integrated d/w 50750 VI problem

Hi,

I’ve just been out to an AEG d/w 50750 PNC 911 234 548 02. The customer says its not been cleaning the pots and they come out wet at the end of a cycle. From the first look at it i found the relay at the front right hand side of the machine to have a burnt contact. The wires for this go diectly to the pcb.
Its seems to me that the machine is not heating. I only put it on a quick wash prog for about 10 minutes, dispensor opened but no heat. No error codes from what i’ve been told but the lady had been messing with the switches before i got there.
Does anybody have any idea whether this relay controls the heater. I know the Whirlpool dishwasher are controled this way.

Any help would be greatly aprreciated.

ps The lady said that for a few days before the problem occured it was making a strange noise. She described it as being like a clockwork toy noise when its been wound up and was unwinding. Was wondering if this noise could have been the noise of the chattering relay?

Cheers

Nick
