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.
What does F 01 error mean on my Webasto Heater, and how to fix it?
The F 01 error code on your Webasto Heater indicates a 'No start' issue. This can happen if no flame has formed even after a restart. Check the fuel supply (tank empty, lines blocked). Clean the burner insert. For gasoline heaters, replace the flame sensor. For diesel heaters, replace the overheating sensor or control unit.
What does it mean if my Webasto Air Top 2000 ST D displays error F 02?
Error code F 02 on your Webasto Heater indicates a 'Flame failure'. This means the flame has gone out during operation and has not reformed after a restart attempt. Check the fuel supply (tank empty, lines blocked). Clean the burner insert. For gasoline heaters, replace the flame sensor. For diesel heaters, replace the overheating sensor or control unit.
What does error F 03 mean on a Webasto Air Top 2000 ST D Heater?
Error code F 03 on your Webasto Heater indicates 'Under-voltage or over-voltage'. This happens when the voltage is less than 10.5 V or 21 V for longer than 20 seconds. Charge the battery.
What does error code F 08 mean on my Webasto Air Top 2000 ST D?
Error code F 08 on your Webasto Heater indicates a 'Drive unit (combustion and hot air blower) break or short circuit'. This can be due to: * A break or short circuit to +Ub: Replace the drive unit (combustion and hot air blower). * The switched drive unit cable has a short circuit to earth or the drive unit is overloaded: Eliminate the cause of the blockage / difficulty in movement. * Burner motor block guard has tripped: Replace the drive unit (combustion and hot air blower).
What does error F 00 mean on a Webasto Air Top 2000 ST D?
Error F 00 on your Webasto Heater indicates a 'Control unit error'. Replace the control unit.
What does error F 10 mean on a Webasto Heater?
Error F 10 on your Webasto Heater means 'Overheating'. This indicates that the overheating fault lock-out has tripped because the heater overheated. Find and remove the cause of the overheating.
What does error F 04 mean on a Webasto Air Top 2000 ST D Heater?
Error F 04 on your Webasto Heater indicates 'Premature flame recognition'. This means a flame was detected before combustion had started. For diesel heaters, replace the overheating sensor or control unit. For gasoline heaters, replace the flame sensor.
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.
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.
