I have a Kenmore Elite 665.16939000 that I found where the heating element was no longer raising the water temperature or drying the dishes completely.
My wife informed me that some time ago the unit gave off a slight electrical burning smell once that seemed to come from the upper right corner, however the unit has continued to work since then - other than the now noticeable dishes that are no longer completely dry.
I started troubleshooting and ran the built-in self diagnostics while probing with my meter. The diag didn't give any errors. I found during the diag cycle, even though the K2 relay on the control board was clicking during its time to turn on, there wasn't any power going to the heater. I pulled out the control board for a closer look and found the underside of the circuit board had burned away the tracing by the K2 relay. Ok, problem solved - go get a new control board.
While looking up where to get a control board, I found I could get a kit which included a heater and a control board for a lower price than buying a control board alone. When asking the salesman why, he just said it's suggested that when changing the heating element you should change the control board with it. As to why the price was cheaper when doing it that way - he didn't know.
Before changing out the existing element, I measured the resistance and found it to be 9.2 ohms. Since the spec said the range was suppose to be between 10-30 ohms for the element, I put the new one in - with 9 years of age, it was probably due.
I put the unit all back together and powered it up. Now the digital display showed the LED's to rotate for a short time and then quit. (Something not seen before.) I pushed the keypad sequence 'sani-rinse / air dry / sani-rinse / air dry' to run the diagnostic and it appears to run without error. All the lights lite up on the control panel. Problem is, it won't start when pushing the start button as it had done in the past.
Tried running a 'Bacteria Clean' cycle and it ran a complete cycle once, however, the cancel button will not stop it once started and when finished it won't run any more cycles of any type.
Could it be that the new control board took out the control panel? I checked the ribbon cable very closely and couldn't see where there was any damage.
Is there any way of testing the control panel pin to pin?
This one has me baffled....
