Water Pressure - Sirrus Gas Boiler

ROK ON

Hello
I have a Sirrus Gas boiler. It stopped working the other night. Flame lights up for circa 10seconds and then it turns off. When it does this a red light flashes - (this red light is marked 50 with a yellow circle around the light and a stop mark with triangle above the light. I understand from a manual,that this is a light indicating water pressure.

The gauge is reading 0.5 bar so I am for the moment going to assume insufficient water pressure.

Question - how do I increase the water pressure? I am attaching a picture often underside of the boiler. You will see in the right hand side a pipe with what looks like a red coloured 'tap' this copper pipe is warm to touch.

On the left hand side is a similar pipe and red tap.
In the centre there is a copper pipe with a yellow tap - this has a label that reads: "valve no.4 isolates incoming gas" I am going to assume that I leave this alone.
Therefore how do I increase the pressure to above 1.5 bar?

Thanks folks

None of them anyway.

Any other extra pipes below that or take a picture of the bot press pipes

I will attach pics of hot press which simian the hall. There is a pipe with tap mechanism on the wall fontenot press that is labelled
Valve No2 isolates CWS and pump.

All the other pipes and taps in the hot press refer to either HWS or heating flow to cylinder or cold feed to HWS.

I should point out that the gas boiler is in a separate room from the hot press.
Thanks

Not there either.

You look behind the cupboards in the kitchen

Can you take a photo of the pipework to the right hand side of the cylinder.
And can you get another one of the lower left side but use the flash to brighten the corner up.
You are looking for something like this. ..

Do any of these pictures help?

This one.

No, apart from both pictures being almost identical, that's your shower pump and it's connections.
