Heater fault test - Balboa BP100 (Okanagan/Saskatoon Spas)

If the Spa is continuously tripping the GFCI, it may be due to a fault within the heater. To confirm if this is the case, follow the directions below.

  1. Power the tub OFF.
  2.  Remove the cabinet panels directly below the topside of the tub to reveal the BP100 Control System.
  3. Remove the lid of the system to reveal the circuit board and following the printed diagram on the back of the lid, proceed to disconnect J11 and J13 connectors from the board as shown below.
  4. With both connections off, restore the power to the tub. If the Spa remains ON with the heater disconnected, the heater is defective and it would need to be replaced. If the GFCI continues to trip, something else is causing the issue.
  5. If the heater has been confirmed defective, keep the tub powered ON with the heater unplugged until it can be replaced. This will ensure the water will continue to circulate, preventing any chances of freezing during the winter time.
