The Nightmare continues... but at least I have my cheap diesel heater as a back up, although no hot water option yet! Alde stated that the system needed to be serviced with the new pink 5 year fluid and by an approved Alde service rep. I did that on Saturday, Andrew from Trent Caravan Services came and replenished the system with the pink fluid and with the Alde Service Pump, but within an hour we had the Blue overheat fail again, both gas and electric failed the same way, but more so on electric supply? Andrew from Trent is a great guy, I would highly recommend him, I'm hoping he can find a solution with Alde on Monday morning, if not I guess I'll have to go to them. Not good for a system that is less than 3 years old and only 3000 miles on the clock, so little use!!
