Hi,
I have a Vaillant combi boiler. The manual is missing so I don't know the model number but I think it's from around 2003.
It's been working fine for the past 2 years we've been here but recently it's stopped shutting off after hot water has been used. The pump remains on and it continues to fire. I don't think it's a case of pumping the excess water out to the radiators. I've also checked the timer to make sure that the water is not set to come on or stay on at any time.
If I turn the boiler off at the main switch and back on the boiler remains off but next time I use hot water it happens again.
Any ideas what this could be? Thanks in advance.
