Above model of dishwasher:
I am working on 2 of these dishwashers.
I put the first one into test for fault codes. LED L1 lights up. Complaint no heating, long cycle, bad cleaning. I will be checking the thermistor for resistance and the heating element. I understand that there is a thermal fuse on the heating element that my be bad. Also, if there is a thermistor problem, the heating cycle is cut out/passed over completely. Also there is no water going up to the upper spray arm. That spray arm has sat in the same position through 2 cycles
I put the second one into test mode for fault codes. The LED L1 and LED L6 light up. Same complaints as above. Looks like the same senario as above. Except, the LED 6 lighting up. According to the service manual this is a rinse aid area issue, but it references that is for the dw20.5 only, not these dw20.3 models. Also, the same upper spray arm has the same issues as the first machine.
Any thoughts gents?
Respect and thanks,
