Wonder if anyone else has had the same problem with the Truma water heater in a Bailey 460/4. When it is turned on on electricity it heats up fine till the thermostat cuts it out, but then it doesnt heat up again. Turn it off for 5 mins and it resets fine but still only heats up once. Previously I could leave the hot tap running for ages and the water would still be hot, now there is barely enouigh to wash a bowl of dishes!. Am told that the thermostat is part of the heater element and needs to be replaced as one, am loathed to spend £70 for a new element assembly until I am sure it will solve my problem. Can anyone give me the benefit of their experience on this one??
