the trouble i am having is that there is no heating and when the dial is turned on for dhw only without the tap running it switches on for about 20 seconds then cuts out . i have had a new diverter valve fitted abvout 3 weeks ago and it was ok up to now any ideas please.

further investigation if i turn it off then turn it for dhw/heating it fires up for heating for a while then cuts out then if i turn the dial to dhw with no tap running it fires up for about 7 secs then cuts out and fires up and off and so on.

Possibly DHW flow switch stuck on. Easy and cheap part to replace, if that's the problem. Would be worth checking through fault finding section of manual (download from Chaffoteaux site) anyway.

i have checked the dhw flow switch and seems to be ok when tap on there is a reading when tap of it reads o.l
