How do I correct my Vaillant Boiler?

Hi,


It's a Vaillant Turbo boiler, functioning fine as regards to the central heating, but no longer supplying hot water? Even on maximum heat, it gets warm then cools down, then gets hot and then cools down again, its not possible to have a hot shower.

We are insured by British Gas - when they came, they said there was nothing wrong with it. Two years ago they changed the diverting valve, since then the problem started getting worse, any help? thanks

on your mixer shower the hot water inlet has got filters it is blocked, dis connect shower and remove shower mixer and clean filter (gauze) wash and put back you will find it should cure your problem..
