Hi, I have just replaced the pcb board on my gloworm compact 100p, it worked great for two days but now i cannot get any hot water only a small amount when i run the tap really slow. the heating seems to be ok but i have noticed the gas flames dont appear to be as high as they used to, has anyone any ideas what the problem may be, many thanks.

If you haven't already, post to this group:

is it firing up when u run the tap or do u need to have the heating
on. im not familiar with the boiler but if its not firing up just by
running the tap it will be a flow switch/diverter valve problem, if
it is firing up by running the tap it may be the temp sensor for the
dhw.
