Truma Trumatic C 6002 EH
The Trumatic C 6002 EH is a combination gas/electric space and water heater designed for caravans, motorhomes, and boats. It integrates a high-capacity warm air heating system with a 12-liter stainless steel hot water boiler, supporting liquid gas, 230V electricity, or combined dual-energy operation.

Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
Operational Fault | Missing supply voltage or blown fuse. | Check 12V battery voltage, check all electrical plug connections, check heater and vehicle fuses. | DIY Safe |
Operational Fault | Set temperature on control panel is lower than room temperature, or the window above the chimney is open (window switch). | Turn the control panel setting to a higher temperature or close the window. | DIY Safe |
Operational Fault | Battery voltage is too low (< 10.5 V). | Charge the battery. | DIY Safe |
Operational Fault | Gas cylinder or quick-acting valve closed, or air supply interrupted. | Check gas supply, ensure chimney cap or cover is removed, and open deck chimney on boats. | DIY Safe |
Operational Fault | Blocked warm air outlets, frozen gas pressure regulator, or too high butane proportion in gas cylinder. | Check individual outlet openings individually, use ice ex-control system (EisEx), or use propane (butane is unsuitable below 10°C). | DIY Safe |
Operational Fault | Missing 230V supply voltage, blown heater fuse, or tripped overheating switch. | Check 230V supply voltage and fuses, check heater fuse, or reset the 230V overheating switch. | DIY Safe |
Operational Fault | Outdoor temperature is below 4°C, causing automatic frost protection drain. | Start heating (at temperatures around 4°C and below, the drain valve opens automatically). | DIY Safe |
Operational Fault | No supply voltage or device/vehicle fuse is defective. | Check 12 V battery voltage, check all electrical plug connections, and check device and vehicle fuses. | DIY Safe |
Operational Fault | Ignition failure, closed gas cylinder, interrupted air feed, or battery voltage too low (< 10.5 V). | Check gas feed and cylinder, ensure cowl is free of covers, check battery voltage and charge if necessary, unlock by switching off and on again. | DIY Safe |
Operational Fault | No 230 V supply voltage, defective device fuse, or overheating switch has triggered. | Check 230 V supply voltage and fuses, check device fuse, or reset the mechanical 230 V overheating switch on the power electronics. | DIY Safe |
Operational Fault | Outside temperature below 4°C causes automatic draining, or lack of 12 V power supply at the drain valve. | Switch on heating (drain valve can only be closed again at temperatures above 8°C without heating mode) and verify 12 V power supply. | DIY Safe |
Operational Fault | Water pressure too high exceeding maximum limit. | Check pump pressure (max. 2.8 bar). Install a pressure reducer if connected to a central city/rural water supply. | DIY Safe |
Frequently Asked Questions
Q: Can the heater run while the water tank is empty?
Yes, the heater can operate on all three heating modes (gas, electric, gas & electric) even when the water tank is empty.
Q: How do I empty the water boiler to prevent frost damage?
Switch off the water pump power supply, open all hot water taps in the kitchen and bathroom, and push the electric safety/drain valve switch down into position 'b'.
Q: What should I do if the 230V electric overheating switch trips?
Let the heater cool down completely, open the power electronics cover, and push the red button (13) back in.
Q: Is simultaneous gas and electric operation possible for summer water heating?
No, gas and electric combined operation is not available exclusively for water heating. In summer mode, the heater automatically selects the chosen electric power setting (900W or 1800W) and gas does not turn on.
