Blinks 7 Times, then Repeats (Water Heating Fault)
you need to test both the water heating element and the thermostat. for continuity. whichever one has no continuity is bad and needs to be replaced. they are both tested the same way. heres a link to show you how. theres a video. http://www.repairclinic.com/PartDetail/Heating-Element-Assembly/W10134009/1381534?modelNumber=GU2500XTPB6
Okay I was measuring the thermistor, not thermostat. I found the thermostat. It is reading .6 Is that within range of "good"? Thermistor tests good within range. On the tech diagram inside the dishwasher that I found when I removed the front cover...there is no range listed for the Hi limit thermostat.
okay so this is what I have done. Both thermistor and thermostat are reading good. I have put the dishwasher in a diagnostic cycle. It ran through with no issues....but the last part is heating element or HEATER. The element was not hot to touch immediatly after the cycle. I have removed the element from the dishwasher. The coating is coming off on my hands. Ohm meter (digital) is showing continuity @ 10.6 ohm, which by the book is within range, right?
