How to Fix / Troubleshooting

Safety first: Turn OFF the breaker before any internal inspection.

  • 1. Power-cycle: Turn OFF the breaker for 2–3 minutes, then ON. If E015 clears and does not return, it may have been a transient error.
  • 2. Listen and observe: On power-up, note any unusual noises (buzzing, repeated clicking) or smells (burning). If present, leave the unit off and call a technician.
  • 3. Visual inspection: With the cover removed and power OFF, look for obvious damage: burnt components, loose connectors, or foreign objects inside the enclosure.
  • 4. Do not bypass safety checks: E015 indicates that internal safety diagnostics have failed. Continued use without repair is unsafe. Arrange for professional service to test and replace the control board or power supply as needed.
