We have a 2014 Sprite Major 4FB with a Truma Combi 4 Boiler.  Quite efficient but we keep getting an error code #15 and the system shuts down.  Have to reset and start again.  No pattern as to when the fault occurs other than it hasn't failed on 12v supply
and gas heating.  Only fails when hooked up.  Been to Truma UK (very helpful) who think it might be the battery charger sending a blip of AC power and tripping it out.  Invetigations are ongoing - Anyone else had any similar issues?  John and Mary
