In June we took delivery of a new (2007) Autocruise Starburst, with which we have been very pleased EXCEPT the mains water heater on the Eberspacher heating system has never worked. The deisel part of the system works well. Discover (who supplied it in the first place) had agreed to honour the warranty, and were most obliging but unable to solve the problem. By a process of elimination we have decided that probably the heating element is not functioning as we have replaced the thermostat (ourselves) and power is getting to the system, but no heating occurs. Has anyone had any similar problems, and can you suggest who may be able to help. We are in North Yorkshire. It isn't the end of the world as we have a good source of hot water from the deisel heater, but that isn't really the point. Our local Discover don't seem to have any knowledge or experience of Eberspacher system and whilst it is under warranty, it has been at the dealers for 3 weeks to no avail, so the most sensible way forward would appear to resolve the problem ourselves. Help please!
