Phewwww....there must be a bug in this website; it's the 4th time that I post my message after 3 failures...
I have an older model Cal Spas Hot Tub ('Supreme'model) from the early 90's and I recently moved it to my new home. I installed 240V 50A circuit and now the air blower and light works but the whirlpool jet and especially, heater are not.
I could live with whirlpool jet not working, but I have to troubleshoot and fix the heater. There's no fuse in the control module(Is it located somewhere else??) but a 'Heater
Reset' button. I tried to engage it, but it hasn't 'popped'.
Any hints or tips on troubleshooting this thing will be greatly appreciated....thanks in advance

Very frustrated

Is this wired with 3-wire-plus ground?

I think the light and blower are 110V and the heater and pump are 220V. If so, one of the hot legs must be open.
Have you tested each hot to ground?
