Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
N/A | Boiler does not operate after switching on (Gas mode) Possible Cause: No 12V power supply | Check the battery voltage (minimum operating voltage 10.5V). Check the boiler fuse on the electronic control unit. If the issue remains unresolved, contact an authorized service agent. | DIY Check / Tech Fallback |
N/A | Boiler does not operate after switching on (Gas mode) Possible Cause: Window open above cowl | Close the window above the cowl. | DIY Safe |
N/A | After switching on, boiler does not operate and red LED comes on after about 30 seconds Possible Cause: Cowl cover is fitted | Remove the cowl cover and/or check for soiling and remove if necessary. | DIY Safe |
N/A | After switching on, boiler does not operate and red LED comes on after about 30 seconds Possible Cause: No gas supply or incorrect gas pressure | Check gas valves and gas cylinder. | DIY Safe |
N/A | After switching on, boiler does not operate and red LED comes on after about 30 seconds Possible Cause: Air in gas supply | To clear the fault and bleed off air, switch the appliance off, wait for 5 minutes and switch it on again. | DIY Safe |
N/A | After a long period of operation, boiler switches to 'Fault' and red LED comes on Possible Cause: Overtemperature sensor has activated | Check the water content, topping up if necessary by closing the drain valve. To clear the fault, switch the appliance off, wait for 5 minutes and switch it on again. If the issue persists, contact an authorized service agent. | DIY Check / Tech Fallback |
N/A | Boiler does not operate after switching on (Electrical mode BGE 10) Possible Cause: No 230V power supply | Connect the vehicle to the local central power supply and/or check the residual current protective device. | DIY Safe |
N/A | Boiler does not operate after switching on (Electrical mode BGE 10) Possible Cause: Overtemperature sensor has activated | Check the water content, topping up if necessary by closing the drain valve. The electric heating element is fitted with an overtemperature sensor; switch off at the control panel, wait for 10 minutes, then switch on again. If the issue remains unresolved, contact an authorized service agent. | DIY Check / Tech Fallback |
N/A | Heats up too slowly with switch set to 850W (Electrical mode BGE 10) Possible Cause: Insufficient heating output selected for conditions | Contact Truma Service or an authorized workshop. | Professional Intervention Required |
N/A | Water dripping from drain valve Possible Cause: Water pressure too high | Check water pressure (max. 2.8 bar). When connecting to a central water supply, a pressure reducer must be used. | DIY Safe |
N/A | Warm water coming out of cold water tap Possible Cause: Hot water flowing back into cold water supply | Fit a non-return valve to the cold water supply in accordance with the installation instructions. | DIY Safe |
