do the lights flash and is the tone continuous or an intermittent beeping?
also, why manually change over? the system is set to auto switch when parameters are met.
i had a simliar fault on the same system, i discconected the battery and all was well
Depends on the install and who did it as LPG components can be placed in various locations and where it would fit!I have just been told that this means that there is a electrical fault .this is likely to be a senser .and most likely the pressure boost sensor. Can anyone tell me where this is and how to test it please
