Bob for Model Number KUDE70FVSS3 The water level is not filling to the proper level - never floats the float. I have replaced the water inlet valve and control board and no change. If the water level doesn't get high enough, the sanitize cycle never works as the water level is well below the heater. When I first start the unit, it seems to begin filling for a few seconds, okay, maybe 5-10 secs, then the drain motor starts and it is hard for me to determine if we are still filling when this happens. During the initial cycle, the unit will go back and forth between filling and draining a couple of times. It does get some water into it as I can see water dripping from the dishes above and everything seems wet, but water never gets hot because it fails to reach the heater. I am thinking the float switch is bad since I have swapped out everything associated with getting hot water. I notice the water level wasn't right after I googled how to determine if my dishwasher was filling to the proper amount. Again, replaced the water inlet valve, heater, temp sensor (think this is part of a unit that checks how clean the water is), controller and temp limit switch, even door switch. Running out of things to change, just ordered the float switch. Think this is a good bet? Yes tried rebooting the controller and some insight on how to do this would be great. I unplugged the unit overnight to obtain a reboot.
Answer Bob, The float switch will be the likely cause with what has already been done. You may want to pull the float to ensure that the float is not cracked or filled with water which will diminish its effect. Read More... Answered by AppliancePartsPros.com | Tuesday, June 28, 2016
