How to increase pressure in Boiler? - no hot shower!!

[yelf]

Hello, we have a Myson Midas B combi boiler. The temperatue gauge is just below 1 and the pressue gauge is JUST above one - on reading the manual this shouldnt be an issue.

but this morning our electric shower showed the Low Pressue warning light and would not heat the water. Having had the heating off now for a half hour it is now heating the water, but we never had this problem before: ie: we could use the shower and central heating at the same time.

No where in the manual does it say how to increase the pressue at the boiler! Can anyone possibly help please?

Thank you.

I'm not a plumber, but the pressure at the electric shower won't have anything to do with your boiler, and the pressure gauge on the boiler just shows the pressure in your Central Heating system - there should be a filling loop at the bottom of the boiler to increase it.

Sounds like you have low water pressure to me - possibly a frozen incoming pipe?
