GFCI Flow Chart If GFCI trips, follow Troubleshooting Flow Chart below to identify the problem: Is GFCI properly connected? Verify Wiring Diagram and reconnect it. Unplug everything, including heater and light cord wires. Is GFCI still tripping? Reconnect one component at a time until GFCI starts to trip. - Page 7 GFCI Trips! If all connections are made, but nothing seems to be working, you probably have a power supply problem. Carry out the following tests to identify and correct the problem: Note that for new installations, GFCI trippings due to miswiring are common. If breaker is wired properly, GFCI trippings may occur when total amount of current drawn by spa exceeds breaker rating.
- Page 8 GFCI Trips! If GFCI continues to trip even after having replaced the transformer, carry out the following tests to correct the problem: 1• Disconnect incoming power lines. If GFCI still trips, there must be a cable problem. Call an electrician! 2•...
