Product review (5 stars): The heat element was fine so I replaced these items as my dishwasher was ...
Had a Clean light flashing problem. Replaced this thermistor and thermostat and module to make sure everything was replaced that needed to be. The heat element was fine so I replaced these items as my dishwasher was giving the 7 flash green clean light action. I have a dishwasher that is pretty much brand new now. A new dishwasher to replaced is $650. I spent about $170 on everything including a new hot water hose. A service call is around $90. That's just to come out and look at it. Replacement parts from the repair man is going to be almost twice you pay from amazon. So if you have a flashing green light it may be your heat element. But if its not,  it could be the thermistor. Then you have to ask yourself what made the thermistor go out. The thermostat? The module? Replace all of them so you know it will work with all new parts.
