Do you know if H1 and H2 would have voltage all the time or just when the heater is being called on. I see that the control panel is separate from the control board behind it. I'm wondering at this point if one of those is faulty. That would explain the buttons not working and maybe the heater is not being requested so its not on. If I cool the water down below 80 maybe it would turn on. I may try this to eliminate a heater problem. If it is the control panel or the board behind it I'll have to remove part of the deck to get to it. Not looking forward to that.
I'll try to call tech support asap.
