This is happening on both drawers.
The incoming water temp is about 25C (less than 85C)
The element is on, but the water temp is about 35C when it dishwasher stops with F3 error.
I took apart one drawer there was no moisture around the temp sensor.
The resistance off the circuit board, measured correctly at 20/30/60C. Same resistance was found when measured at controller connector.
Ran a fast test cycle and turned on the temp display mode. The temp displayed was 80C during fill after about 2 minutes, it displayed 85C and stopped with F3 code. Water temp inside tub was 35C.
Temp sensor on 2nd drawer measured correct at controller connector.
I cannot swap controllers because both have the same problem. Temp sensor resistance is good, but controller displaying incorrect water temp.
It appears the controller is converting the temp sensor resistance incorrectly, is this adjustable? Does this indicate the controller is bad?
