worcester 24cdi rsf. the hot water only works for a minute or less then cuts off with no fault code flashing. why?

works longer on half bore but on full still flows but boiler cuts out with no flashing lights

Need more info. Does the boler come on as soon as you turn on the hot tap? ANd then go out.... and if you leave the tap running.... ?

 

[bdog]

yes it fires up straight away then cuts out after between 10 secs and about 30 if you leave the tap running it doesnt come back on and only fires up in the first place if the taps on full bore

its the diaphragm, get someone in to fix it cos its not going to be long before its not going to come on at all.
