Worcester Bosch Highflow 400 low pressure

DiWhy_1 · 24 Aug 2022

This is probably a stupid question as I'm pretty lousy at this kind of thing. I moved house a week ago and today I've noticed I've got no hot water. The boiler shows low pressure so I guess I just need to top it up, but I can't for the life of me find the top up valve. Can anyone give me any hints? I found an online manual but it's entirely unhelpful.

Show us some pics of the pipework below the boiler.

Take the front cover off and it’s at the bottom, you will have to fit the hose between the two valves.
