Potterton Performa 24

We're having issues with the pressure on our Potterton Performa 24 boiler, it currently stands at zero. When the water is turned on it goes up to 0.2 absolute max. We're having issues getting hot water in our bathroom because of this.

I'm attaching a picture of our pipes - I've marked the two ends of the silver flexi pipe as 1 and 2, and also indicated where there is a flathead valve. One end is accessible, the other is not really as it's so close to the wall...

I know we're supposed to open a valve at one end of the silver flexi pipe (the flathead screw I'm guessing?) but we don't seem to have another valve on the other end. What should we do? Just open one until we hear water filling?

Please advise!

Open the valve marked 1. If the other valve is open the slot for screwdriver would be in line with the pipe ,if it isn't you need to open that as well. Stupid position to have fitted it though !!
Read the manual.
I did this for my daughter's boiler and you have to open 2 valves on the boiler.

Yours might be same.

But as per the post above as well.

Always read the instructions.
Thanks for this. The issue is we can only access one of the valves. The other is either right up against the wall or it doesn't exist. We can't get there to look and say for certain.

Are there definitely two valves? What would happen if we just opened the valve marked 1?

Open valve marked 1 ,if pressure tops up all good. If the second fitting can't be reached then it can't be necessary to do so. I can't make out from your pic exactly what 2 is. It may be an isolation valve but I doubt it ,more likely to be a non return valve.
