It has digtal controls. The pressure swicth is open with jets off and closed whe jets are on low. I'm getting no power to the heating element. The cover is on it. If i'm not getting power to the element, then I doubt its going to heat. I'm guessing I might have a bad relay on the board maybe?

I will check the pressure sensor again tomorrow. What else could be wrong? Is there anything else I can check? It seems that something is not telling the element to come on

is there a way to test the pressure switch?

I have also checked the jumpers to make sure the jumpers are correct. Could the board be bad? Do you have to buy the whole control box, or just the board. I also found a place to repair boards. Is this a better way to go?

checked the thermistor. Temp was about 77 degrees and reading was 9.5 ohms (20k.)

I turned the jets on high, and then off. I waitied 10 minutes and thelow speed came on, but still nothing at the element.

The measured the heating element and it measured 13 ohms.

Model YQ 120V A buddy gave me this hot tub, and everything works great but the heater. I have checked for voltage at the heater and nothing. I have also tried jumping the pressure switch and nothing. All the fuses seem to be good. Is there anything else that I can check? Everything appears to be working but the heat.
