I have a f30e therma condens boiler, in the summer i had hot water great but i turned on the heating the other day and now i only get hot water if heating has come on! if i try to run the water without heating then i only get cold water the first year that i had it i had to have a new heat exchanger put in but this has made no diffrence, any idea's

faulty diverter valve or pcb most likely the first it diverts the water from heating mode to stop it pass into rads and into heat ex for the hot water. british gas charge a one of fee of £150 parts and labour inc doesnt matter what the fault to non members hope this helps
