How to Fix / Troubleshooting

Safety: Do not attempt repeated resets of the breaker. Unplug the unit and keep it unplugged until inspected.

Steps:

  • Inspect for moisture: Check the base and around the power entry for signs of leaks or condensation. Dry thoroughly and identify any source of leakage.
  • Check power cord: Look for cuts, crushed sections, or exposed conductors. Replace the cord if damaged.
  • Internal inspection (advanced): Open the housing and look for burn marks, melted insulation, or corrosion on the PCB and wiring.

Because this involves safety-critical faults, further diagnosis and repair should be performed by a qualified electrician or service technician.
