dishwasher Kitchen Aid model # KUDi01iLBT6 Sn# FS0205057 type 577-0

Hello,
My 9 yr Kitchen Aid DW has been stopping in mid cycle with the clean light blinking. For a while this only happened 2x a year, and resetting the control panel by this process ((close the soap dispenser door, close the dishwasher door, and toggle between hitting high temp scrub and energy save dry several times until all the leds light up, press cancel) this would allow a good restart and the DW would run fine for a while. But now toggling between the two buttons and restarting only works about 1 in 10 times. I have been accommodating this by washing, toggle/cancel/restarting wash with no soap to rinse the soap , but I have no dry.

I have placed a right side cup on the top shelf and it will fill up in just a few minutes so I have plenty of water.

The water is coming from the hot water heater. It seems a little colder than the tap but I think that is because it looses a little heat sloshing around in the DW. We did turn up the hot water heater but to me the dw water doesn’t seem quite as hot as the tap.

I am about to try this… "You’d need to uninstall your dishwasher, disconnect power and lay it on it’s back to check the resistance of the heater as well as the resistance of the high limit thermostat to confirm if they were bad or good. You should get tangible reading of between 5 and 30 ohms on the heater if it’s good and less than one ohm on the high limit thermostat. If both of those devices check good, then replace the control board because that’s the one device you cannot test"

And I am going to try this … " There are 2 switches that close 2 circuits when you close the door. The one on the right side is not staying closed, thus the heating circuit is shutting down. An easy test is to trade the 2 wires on each switch to the other side. This should eliminate the clean light blinking and cause the dishwasher to just turn off. The newer designs have eliminated this double switch design"

Which should I try first? Or do you have any other ideas?
Thanks

I think I may need to revise my reset procedure.
I have been toggling between hitting high temp scrub and energy save dry and then pushing cancel as soon as I saw solid lights, but I don’t think I should press cancel as I don’t think that allows the DW to run the diagonistic cycle. I think I need to toggle and then let the DW automatically run the diagnostic cycle. But I am not sure what to do next?

Also how do most folks check the water temp. My meat thermometer starts at 140 and the thermometer out of the med cabinet only goes to about 107. I Guess I need to buy a hot tub thermometer or is there a better way?

Do you have to take the door apart to get to the control panel?
