Possible Causes
How to Fix / Troubleshooting
Danger: Repeated breaker tripping indicates a serious fault. Do not repeatedly reset the breaker without investigation.
- Check breaker rating: Confirm the breaker size matches BWT’s installation manual and that the heater is on a dedicated circuit.
- Inspect wiring: With power off, inspect visible wiring for damage, burns, or loose connections.
- Isolate components (technician recommended): A professional can disconnect the fan or compressor to identify which component is causing the trip.
Because of shock and fire risk, breaker-tripping faults should be diagnosed and repaired by a qualified electrician or technician.
