Technical Tips - Gas Appliance Resets

​For new RV Owners or people that have purchased a late model RV, hand over day can be a little overwhelming in learning how to operate the new systems.
 
One common thing we tend to see is people having issues with the hot water heater or fridge faulting on gas. When your Truma Combi hot water heater faults on gas you will most likely see a code “E517H” on the control panel. When the later model Dometic fridges fault the fridge will display a blue LED light under the ! mark on the front panel.
 
Most of the time we see this happen due to the gas bottle being turned off before the appliances have been turned off. If you wish to turn your gas bottle off, it is important to make sure you have turned your hot water and heating off, then make sure your fridge has switched to the desired mode 12V, 230V or completely off. This will prevent the above faults from occurring.
 
If you have a Dometic 10 series fridge, to reset the fault you simply need to hold down the power button for 3 seconds until you hear a beep, this will reset the fault code. If the fridge turns off, you have held the button too long, turn the fridge back on and try the same process again.

Here is a simple video below to help.

For the Truma heater system, if you look at the Truma control panel and scroll down to the flashing ! icon on the bottom of the screen and select it you will see a message, 15-minute timeout, this time out will count down to 0 and you will then be able to restart your Truma system once again. If this error persists you will need to undertake a hard reset on the heater unit itself.
