My dishwasher runs fine until it gets to the dry cycle. It starts to beep and the drying cycle does not run. I changed out the sequence switch but it did not help. Does the control board need to be replaced?
You will want to check your heater circuit to make sure that it is working properly. Make sure that your heater is good and that any thermostats for the heater are good. If these check ok then the control board would be faulty and need to be replaced.
