Many modern European motorhomes are fitted with the Truma Combi Habitation and Hot Water Heating System and winter is the time of the year when the unit usually gets a good workout.
Unfortunately, winter is also the time we get the most related trouble shooting calls and are often asked how to reset the system.
The most common fault is when you either run out of gas or have changed the gas bottle without turning the hot water system off prior and the boiler fails to ignite on gas.
Your operating screen will show the E517 H fault code and your system will not work. Please ensure the system has access to gas prior to resetting it.
Option 1: Ensure both your habitation and hot water heating is turned off completely (no items displayed above the line on your Truma screen) and wait for 20-25 minutes. This often resets the system and there is no need to perform a hard reset (Option 2).
Option 2: Ensure the fault code is displaying on your operating screen. Perform a hard reset. Refer to video link below for further details.
