Hva betyr feilkoden?
The heater has gone out in an impermitted way while running at full output, which sets the code and switches the heater 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
- The intake pipe to the fuel tank has moved out of position
- Flame sensor clogged with soot
- Damaged flame sensor
Hva du kan gjøre
- 1Check that the tank has enough fuel for the heater to run at full output
- 2Clear the code and start the heater again; if the code returns, the fault is still present
- 3If you have a diagnostic tool, read whether a flame was detected once the heater has finished running, and note whether it went out earlier
- 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
