Hva betyr feilkoden?
The heater has gone out in an impermitted way while running at half speed, and the code is set and the heater switched off. The cause may be a damaged fuel supply or air pockets in the fuel line, an intake pipe in the fuel tank that has moved out of position, or a clogged or damaged flame sensor.
Mulige årsaker
- Damaged fuel supply or air pockets in the fuel line
- Intake pipe in the fuel tank has moved out of position
- Flame sensor clogged with soot
- Damaged flame sensor
Hva du kan gjøre

- 2Clear the code and start the heater again; if the code returns, the fault is still present
- 3If you have a diagnostic tool, after a completed heater run, read whether a flame was detected
- 4Look for damaged or pinched fuel lines and for signs of air in the fuel line; fuel line work should be done by a workshop
- 5If the fault returns, have a workshop check the intake pipe in the fuel tank, the flame sensor and the combustion air flow
