Boiler problem, once again :(

[zippyd]

Can someone please advise me on my problem. I have a heatline c24, it was already in the house when we bought it, the problem is that the dhw seems to cut out at a certain temperature. I can run my hot tap and watch the boiler start and stop continuesly, the water temperature then obviously goes from hot to cold. Any advice would be greatful, thank you

HI

1.hot water diaphragm split/damaged
2. hot water sensor faulty

Most likely thing that could cause this is blocked dhw plate heat exchanger(full of crap) other then that it could be the dhw temp sensor. When you run a tap is all or most of the lights on the front on or the light with a tap symbol flashing? Then it is the dhw temp sensor

btw where do you live in the country?

Thanks for the advice, I got in touch with heatline and they e-mailed me the manual. I am pretty sure it's the sensor so gonna get hold of one. In the meantime I'll check for blockages

Ps I live in Blackpool!!!

I'm about to move to a new house in which the same boiler is fitted
There is no manual or anything to tell me how to deal with it
I would be grateful if you could forward to me the manual they emailed you
