utah-tub Posted August 30, 2017 Report Share Posted August 30, 2017 I have a 2003 Sundance Sweetware Palmero hot tub which was working fine for years. I didn't run it for a year and then when I turned it back on it would trip the power breaker when the heater would click on. I checked around and everyone said it was a bad heater so I bought a new heater and installed it. No change. I then heard people say that it was my circuit board with a bad lead. I bought a new circuit board and installed it, NO CHANGE. I know the power is good because when I don't have the heater connected on the board the jets run fine. Gotta say this has me stumped! All help would be appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
Jersey Hot Tub Repair Posted August 30, 2017 Report Share Posted August 30, 2017 Silly question, but is the heater connected properly? If the heater is connected but the spa is not calling for heat, does the breaker trip? Or does it trip only when the heater relay closes? If disconnecting the heater allows the spa to run, and the breaker trips with the heater connected, it certainly sounds like a heater issue. Maybe they sent you a bad heater? Is there a bonding wire, and have you connected it properly? Quote Link to comment Share on other sites More sharing options...
utah-tub Posted August 30, 2017 Author Report Share Posted August 30, 2017 Thanks for taking the time to reply! I was checking the hookup and it seems like the grounding pole had slipped lose. Once I reconnected it no longer tripped the breaker. Now I have an F1 error to contend with, I'll try the filter first but guess the flow control will be the problem if that doesn't fix it.

Jersey Hot Tub Repair Posted September 1, 2017 Report Share Posted September 1, 2017 F1 usually means the circuit board things the flow switch isn't closing. Could be due to a bad circulation pump, a bad flow switch, or bad contact where the flow switch goes into the circuit board. You've got that black plastic connector with 3 or 4 sensors in it going into the top of circuit board? It's easy to pull a wire out of that connector while you installed your new circuit board.
