How to Fix / Troubleshooting
Safety: Turn OFF power and do not bypass safety devices.
- Inspect for moisture: Look for water leaks or condensation inside the unit and correct any plumbing issues.
- Test elements to ground: With a multimeter, measure resistance from each element terminal to ground. Replace any element with measurable leakage.
- Check wiring: Inspect supply cable and internal wiring for nicks or crushed insulation that could leak to ground.
- Electrical system check: Have an electrician verify that the circuit is wired correctly with proper neutral and ground separation.
- Retest: After repairs, reset the GFCI/RCD and test operation. Persistent trips may indicate a failing control board or persistent leakage requiring professional diagnosis.
