You'll need a GSR engineer to visit.

ok thanks but do you have any idea what might be wrong please? Trying to get an idea whether it is a major or minor problem.

Do you have a hot water cylinder or a combi boiler?

I have a hot water cylinder

Right. In your airing cupboard you should see a setup like this y plan -



or this s plan



Which do you have?

Hi, thanks for your help Croppie. I only have one other valve so I assume I have the Y plan. This valve was replaced last year and is currently set to Auto instead of Manual.
