ChuckyDee Posted March 16 Report Share Posted March 16 Spa is about 12 years old, came out recently to find the gfci tripped and water cold so it had been off a few days. After restarting, spa ran normally but heater was not heating. Replaced the heater with a 4.0kw replacement and refilled. Touched nothing on the motherboard and re-used the 2 electrical leads that go from motherboard to heater tube. Spa starts normally and pumps and controls work. After system calls for heat, a loud crack and spark and smoke appears near the relays and the GFCI trips. If I leave the heater tube disconnected, the spa runs and the motherboard wires are putting out 240. Of course, these relays are soldered on the board, so not easy for me to replace. Question: worth trying to find a shop to remove/replace the relays or just buy a whole new spa pack? This one is Balboa 56286-01 and its no longer made. Thanks!

Where are you located? Remove the board and look on the back for damage Looks like a Balboa revolution pack with a small circuit board on top of a larger circuit board on top of the heater. Is it possible the middle board is touching something metal below it? Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted March 16 Report Share Posted March 16 Do you have pump 1 (2 speed- 4 wires) and pump #2 (1 speed 3 wires) in correct position? Quote Link to comment Share on other sites More sharing options...
ChuckyDee Posted March 21 Author Report Share Posted March 21 Hi, I'm in Texas. The middle board does not appear to be touching anything. The pump wires have not been touched or moved in 12 years, so I would think they are in the correct position. In the 3rd picture above, look for the C 2009 imprint on the top left of the circuit board, You can see a slight discoloration on the board there, and below J24. That is the only damage I can see...

CanadianSpaTech Posted March 21 Report Share Posted March 21 Usually it is the heater relay but you state you still get 240 off the board. Did you install just the heater element? Did you look down the tube and ensure the element was not touching the sides of the heater tube? I would be checking. @ChuckyDee Quote Link to comment Share on other sites More sharing options...
Fred M Posted March 28 Report Share Posted March 28 If there is v220 at the heater leads the relay is already closed...correct? No flash until its hooked to element, possible you were sold a bad element? Quote Link to comment Share on other sites More sharing options...
