Hi
I have a Vaillant Turbomax 828E, 8 yrs old this month, has recently started playing up again. The problem is CH comes on by itself and wchich some how affects the not wate temp, which is not as hot as before.
I can hear this when this happens, as the pump comes on the CH pipes start rattling in my bedroom !!
I've checked the timer and and reset it so that no heating is required but problem still exists and is intermittant. I've turned the temp right down to stop this but not sure where to go next. Is this the timer (manual clock in this case) or the diverter valve etc.
any help will be appreciated.
thanks in advance
