Mend Potterton Performa 24 Boiler Divertor Valve Hot Water

Faulty potterton performa 24 divertor valve?

I appear to have a problem with the hot water only valve on my potterton boiler, Heating mode is fine and it warms the hot water but it is never fully hot. When switched to hot water only the boiler does not light up and consequently there is no hot water at all. Is there any easy solution to this or does it require a replacement valve?

not sure if this might help, but i had a problem on pcb,and traced it to a faulty capacitor and changed it, but have 2nd fault same as you with hot water, noticed pump jamming and running slow, suspect restricting flow to heat exchanger, water ok if flow turned down,
going to change pump front with known good one, will post results.
