Have an odd situation that started a week or so ago. The dishwasher was running to completion and dishes were either still dirtyish or the dishwasher pod was not dissolved and the dishes basically unwashed.
The model is a GE GDT535PSJ2SS.
After digging into it more and watching several cycles and testing it in between cycles, the issue appears to be with the inlet water temperature. After initial fill, if I open the dishwasher and touch the water in the sump, it is cold.
The dishwasher is connected to a separate tap from the hot water on the sink (likely the same line with a Tee behind the backing) which means I can't run the hot water tap till hot and then start the cycle. Further, playing with the hot water in the sink, I noticed that on opening the tap and setting it to hot, the water is luke warm, then cold then progressively hot.
My theory was a bad mixer in the kitchen sink tap causing backflow of cold water into the hot line. But closing the hot water off in the sink didn't seem to affect the first test.
I am planning to shut off all other mixer taps in the house and run some more tests. Any other thoughts?
Thanks in advance.
