Our dishwasher is not heating, I checked our heating element and it was bad, so I replaced it and its still not working. I check thermostat with meter and it read o ohms, and still no heat. Could it be a bad control board or am I missing a step in this process?

How do I replace the high limit thermostat. I replaced the heat element and the dishwasher is still not drying. I have heard that this is most likely the culprit.

Latest Questions

Dishwasher not drying - high-limit/temp thermostat or heating element Everything else seems to be working fine but the dishes are not drying. From what I've read, it may either be the high-limit/temp thermostat or the heating element. Are the high-limit thermostat and high-temp thermostat the same thing? Some sites seem to have the same item with different names. How can I confirm which is the issue?

Dishwasher doesn't appear to be getting dishes cleaned. After running for a couple minutes can reach in and the heating element is cool. Could the element be affecting the cleaning?
