We have had the bolier for approx 5 Years with no probs. Lately we have no hot water from the kitchen tap and only from the bathroom if turned on full. Central heating is fine. I think it must be a flow rate sensor or is it the divertor valve? If so can you get replacement diaphragmn if so where would i get one

I finally found a diverter valve for £40.00 and fitted it myself. Not an easy job but works perfectly now.
