6. Risoluzione Dei Problemi
This section addresses common issues you might encounter with your diesel heater.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Il riscaldamento non si avvia | Basso volume della batteriatage, no fuel, clogged fuel line/filter, faulty glow plug. | Check battery charge, refill fuel tank, inspect and clean/replace fuel components, check glow plug. |
| Codice di errore E032 | Ignition plug short circuit (faulty glow plug or control board). | Inspect and replace the glow plug. If the issue persists, the control board may need replacement. |
| Potenza termica insufficiente | Low power setting, blocked air intake/exhaust, incorrect altitude mode. | Increase power setting, clear blockages, ensure correct altitude mode is selected. |
