Possible Causes

Water intrusion into pump motor, Shorted heater element to ground, Damaged wiring harness in equipment bay, Incorrectly wired GFCI or neutral-ground fault

How to Fix / Troubleshooting

Safety: Repeated breaker tripping indicates a potentially dangerous fault. Do not bypass the GFCI.

  • Step 1 – Visual inspection: With power off, open the equipment bay and look for obvious leaks, wet components, or burned wiring.
  • Step 2 – Isolate components (for technicians): Disconnect one load at a time (heater, pumps, blower, ozonator) from the control pack and try resetting the breaker. When the breaker stops tripping, the last reconnected component is likely the culprit.
  • Step 3 – Check heater: The heater is a common cause of GFCI trips. If disconnecting the heater stops the trip, replace the heater assembly.
  • Step 4 – Verify wiring: Have an electrician confirm that the GFCI is wired according to Catalina's diagram, with no shared neutrals or incorrect bonding.
