I have a Caldera Utopia, 2006. It starts, runs through the cleaning cycle and will get up to temp but the #1 pump won't shut off. The display shows the pump off but it continues to run. Then if you let it run, it will heat past what you set the temp at. I took the cover off the control panel, you can see the LED for the heat go off, hear the relay but.. it just keeps on going.. Took the PC board out, no obvious burns/shorts/damage.. also removed the filter incase it's flow related.. Could the flow switch cause the # 1 pump to continually run?
