If the heat light does not come on means flow/pressure switch is not making contact. If the pump is running...check the flow switch.

I just got a chance to view your response and yes the pump runs and i can press topside button to swich speeds, before writing to this site, last week i did try to disconnect flow/ press. wires from board and jump connection but the power cord gfi would trip and nothing worked when reconnected to board pump worked but still no heat light . I will check wire contacts on flow pressure switch in morning (how else should I check this switch?
Expert:  Billy replied 2 years ago.
are you sure it was the flow switch you bypassed? should not have anything to do with pump assembly
Customer: replied 2 years ago.
I pretty sure it was flow switch, it screws into the top of heater and has 2 wires that clip on to contacts ,it might have been the temp sensor i dissconnected from board any way how do i test flow switch is making contact
