Looked at above Bosch dishwashers, did not find wire diagram in either one. I thought they were stuck in a pocket in the base behind the toe plate. Not behind outer door panel, so anyplace else I should look?
Customer says it doesn’t clean and dishes are not hot like before. I did the following checks while it was washing. Heater circuit (R – W/R wires) had 120vac and 9 amps. NTC (O-O wires) was at 25.56k ohms and water was 95 degrees. Wash motor was pulsing, I am thinking the washer is trying to heat the water. Does anyone have a wire diagram / tech sheet for this model? Any suggestions on what to look for?
This unit has a timer, so I checked all wires on the timer. To ground, B, W/R, PU, GY, AND GY/B all had 120vac. GY/B had 8.86 amps at one point. I am guessing this is the heater circuit? A thermostat on top of the door inner panel (W – Y wires) was open.
Anyone with a wire diagram / tech sheet for this model? Any suggestions on what to look for?
Replacing the heater assembly will also replace the NTC and the Aqua sensor, as they are integrated into the part.Here is the link below for the diagnostics and error codes.
