What does this mean?
These errors occur when the heater is not receiving enough gas, even if there is still enough gas to cook.
Heating and refrigeration require more gas than cooking.
Models this applies to
Volkswagen Grand California
Fiat Ducato
Step-by-step solution
1. Check the gas bottle
Make sure there is enough gas in the bottle
Low gas levels may still allow cooking but not heating
See video on how to check the gas supply
2. Check the gas connection
Ensure the gas bottle is properly connected
Make sure the valve on top of the bottle is fully open
See video on how to open the gas valve
3. Check internal gas valves
Locate the internal gas valves
Usually under the kitchen sink or under the rear seat
Make sure all valves are in the open position (follow sticker instructions)
See video on how to check internal gas valves
4. Reset the Truma panel
Press the rotary button to confirm or clear the error
Note: the first press may only activate the screen
See video on how to reset the panel
5. Wait 15–20 minutes
After resetting, wait 15–20 minutes
Keep the system on and do not interrupt power

Good to know
These errors are usually related to gas supply, not a defect
Always check gas levels first
Avoid resetting the system multiple times without fixing the issue
