The wiring diagram mentions a fuse but I can't find it.
Is this the fuse you are seeing (see attachment below) on the diagram?
If there is one I would guess its part of the heater assembly as I don't see a fuse listed in the parts list.
Did you check to see if the heater switch is working?
I have not had to work on one of these yet, so I am just going by what I have found in the manual.
Are you able to check for voltage at the heater during the drying cycle?
What is the customers complaint with the dishwasher?
