Hello there

I have a Vokera Linea 726 that is barely 18 months old fitted in a new
house. It has already packed up once, and had a new PCB fitted under
warranty. However the warranty has now run out, and the boiler is now
very reluctant to supply hot water. If I turn a hot water tap on
partially, then the water gets very hot, however, if I turn the tap on
full the water then cools back down again. This problem has occurred
suddenly, and not developed over a period of time. I have read through
loads of other topics about Vokera boilers, and there seems to be a few
too many problems with them for my liking! If anyone would be able to
offer advice as to what may be wrong with mine, this would be very much
appreciated.

Many thanks in advance

James.
