Issue Description: This error indicates a gas supply error, which may prevent the Truma heater from operating properly, even if there's enough gas to cook.
Steps to Resolve:
- Check Gas Supply: Ensure that the gas bottle still contains gas. It’s important to verify there’s enough gas as low levels might not sufficiently power all appliances. Remember, even though there might be enough gas to cook, the amount required for heating and refrigeration is significantly higher.
- Verify Connection: Double-check that the gas bottle is connected properly. Ensure the valve on top of the bottle is fully open to allow gas flow.
- Inspect Internal Gas Valves: Depending on your vehicle model, locate and open the internal gas valves. Confirm they are all in the open position, as indicated by the sticker guidelines.
According to your model, look for the valves under the kitchen sink or under the rear seat. - Monitor the Panel Indicator: After ensuring all valves are open and the gas bottle is properly connected, check the TRUMA panel.
- Confirm or delete the fault code by tapping the rotary push button. Please note that the first tap might only activate the backlighting of the control panel.
- Allow Time for Correction: Reset the panel and maintain the current setup for 15 to 20 minutes.
Note: If the fault 507, 516 or 517 is displayed in the heater’s control panel, switching the control panel on and off does not help. This does not delete the fault, but blocks the heater for 15 minutes. The heater is also blocked for 15 minutes if the fault 507, 516 or 517 is deleted four times without the gas supply being established.
Intermittent Flashing - fault 507 / 516 / 517
The fault code 507, 516 or 517 flashes because the heater is still in a 15-minute blocking time. This was possibly caused by the heater control panel being switched off or because the heater’s 12-Volt supply was interrupted. The heater is also blocked for 15 minutes if the displayed fault is deleted four times without the gas supply being restored.
- Wait out the 15-minute blocking time for the heater. During this time, do not switch off the heater’s control panel and also do not interrupt the power supply.
- As soon as the heater’s blocking time has expired, the fault is then displayed permanently rather than flashing. It can now be deleted as described in the point above.
