Hi, left the caravan with battery a few months. Removed battery and hooked upto electric to keep heater on. Issue I’ve got now is the control panel says e3. It’s a swift europa 2008 Apparently it’s a comms issue . All breakers are on. Would this be a knackered controller? Any help would be most grateful. Thanks

I have mate, unfortunately most issues go towards a different model and a simple reset on the fuse box which this hasn’t got..

Try actually disconnecting both the control panel and the heater unit from the 12v supply, bit like control/alt/delete with a computer. Got to be worth a try at least, just leave them both disconnected for a few minutes.
