Main Combi 24 HE no pressure how do I replace it?

jjenj · 23 Jul 2007

Hi can anyone help. The combi boiler is showing 0 pressure and it should be 0.5 when cold. There is also a flashing red light indicating a drop in pressure but how do I restore the pressure? Can anyone advise.

Thanks in advance

You will either have a filling loop under the boiler with an isolating tap at either end or a built in loop under the boiler. I think it will be the former. Open the valves and let the pressure increase to around 1.2 bar cold, then shut both.

Have you got a leak? Why did the pressure drop?

Many thanks for the advice....it worked.
Think the drop in pressure is because we are currently fitting a shower cubicle and have been repeatedly turning the water off and on.

Thanks again

Turning the water off and on will not affect the system pressure, bleeding radiators will lower pressure as will a leak on either your system or your boiler.
