Why Aqua-Hot Diesel-Burner’s Combustion Process doesn't start?
- Nnancy98Aug 1, 2025
If the diesel burner's combustion process doesn't take place in your Aqua-Hot Water Heater, several factors could be at play. Check for loose harness plug connections at the control unit, ensuring they are secure on the underside. An open “E” or “F” fuse at the Aqua-Hot could also be the culprit, so replace it if necessary. Also, verify that fuel is reaching the diesel burner by inspecting the fuel filter and fuel system. Lastly, a defective fuel nozzle can prevent combustion, so consider replacing it.
