Mend Glow-worm Combi Boiler Low Water Pressure Heating

low water pressure light on my combi boiler?

the low water pressure light keeps flashing - usually first thing in the morning. How do I solve it? It is a glow worm combi boiler and the problem has started since I put the central heating on.

in morning what is pressure guage reading, if around 1/2 to 1/4 of bar low pressure light is telling you system needs water (add to approx 1 bar via filling loop)

when boiler system heats up water will expand pressure will increase hence low water light would go off
