How to Fix / Troubleshooting

Safety: Avoid repeated resets without diagnosis to prevent gas accumulation.

  • Check gas supply stability: Confirm that gas pressure is stable and other gas appliances are working correctly.
  • Review previous faults: Check the Hoval controller history for preceding error codes (e.g., A01, A02) and address those root causes.
  • Single reset: After correcting obvious issues, perform a single reset and observe the full start sequence.
  • Call technician: If lockout recurs, a qualified Hoval technician must check combustion settings, gas valve, and control logic.
