How to Fix / Troubleshooting

Critical safety warning: Repeated breaker trips indicate a serious fault. Turn OFF the breaker and do not reset repeatedly.

Steps:

  • 1. Inspect for leaks: Check for water inside the electrical compartment and repair any leaks before proceeding.
  • 2. Test heating element: Measure resistance between each element terminal and ground. Replace the element if a low resistance path to ground is found.
  • 3. Inspect wiring: Look for chafed or pinched wires contacting the metal chassis. Repair or replace as needed.
  • 4. Isolate circuits: Disconnect the element and try powering the unit (without heating). If the breaker no longer trips, the element is the likely cause. If it still trips, the PCB or other wiring may be at fault.

Professional help: Due to shock and fire risk, have a qualified technician complete diagnosis and repair.
