What does error F 05 mean on Webasto gasoline heaters?
Error F 05 on Webasto gasoline heaters means 'Flame sensor interrupt or short circuit'. This can happen if: * The flame sensor circuit has a short circuit to earth. * The flame sensor circuit has a break or short circuit to +Ub. In both cases, replace the flame sensor.
Why does my Webasto Heater cut out automatically?
The Webasto Heater might cut out automatically due to several reasons: * No combustion after start or restart: In this case, switch the heater off and then on again. * Flame extinguishes during operation: Switch the heater off and then on again. * Heater overheats: Check that the hot air system is clear, allow the heater to cool, switch the heater off briefly and then on again. * Battery voltage too low: Charge the battery.
What does error F 15 mean on a Webasto Heater?
Error F 15 on your Webasto Heater indicates 'Nominal sensor break'. This is caused by a nominal value potentiometer circuit break or short circuit to +Ub. Check the cables and replace the control element.
What does error F 14 mean on a Webasto Heater?
Error F 14 on your Webasto Heater indicates 'Overheating sensor incorrect position'. This is due to incorrect positioning of the overheating sensor. Position the overheating sensor correctly.
What does error F 12 mean on a Webasto Air Top 2000 ST D Heater?
Error F 12 on your Webasto Heater indicates 'Heater fault lock-out'. This means the heater fault lock-out has been activated. Remove the fuse and then refit it.
What does error F 11 mean on a Webasto Heater?
Error F 11 on your Webasto Heater indicates 'Overheating sensor interrupt or short circuit'. This can happen if: * The overheating sensor circuit breaks or short circuits to +Ub. * The switched cable of the element has a short circuit to earth. In both cases, replace the overheating sensor.
What does error F 09 mean on a Webasto Heater?
Error F 09 on your Webasto Heater indicates 'Glow pin interrupt or short-circuit'. This can be caused by: * Glow pin: Break or short circuit to +Ub * Glow circuit The switched cable of the element has a short circuit to earth. In both cases, replace the glow pin.
What is error F 07 on a Webasto Air Top 2000 ST D?
Error F 07 on your Webasto Heater indicates 'Metering pump interrupt or short circuit'. This can happen due to: * Break or short circuit to +Ub: Check cables / replace metering pump. * Short circuit to earth: Check cables / replace metering pump.
What does error F 06 mean on a Webasto Air Top 2000 ST D?
Error F 06 on your Webasto Heater indicates 'External temperature sensor break or short circuit'. This can be due to: * Temperature sensor circuit short circuit to earth: Check cables / replace temperature sensor. * Temperature sensor circuit break or short circuit to +Ub: Check cables and terminating resistor / replace temperature sensor.
What to do if my Webasto Air Top 2000 ST D produces black smoke?
If your Webasto Heater produces black smoke, it could be due to a blocked combustion air and/or exhaust system. Check that the combustion air and exhaust systems are clear.
