I've got a CD28i which is nearly 2 years old and has been great until recently. A problem whereby the hot water tap light flashes and cuts off the water heating is becoming more frequent now. Turning the power of and on resets it and it works for a minute or two then it cut's out again. The central heating is fine though, any ideas?

That fast flash indicates a flue fault, most comon on the 28cdi would be the air hoses from the fan to the air pressure switch, they can perish at the fan end ,any tiny crack or hole will drop out the air pressure switch particulally on max gas (hot water), other than that your fitter would have to check the flue and fan for the usual faults.
