I have a Boiler Combi 24 (UK) and this morning I just noticed that the pressure indicator is pointing to 0. However everything is working fine, I have heating and hot water.
Usually when the pressure is at 0 the boiler indicates (Failure) and there is no heating / hot water..
- I have tried to reset the Boiler but no luck
- I have tried draining the boiler, once all the water got out the Boiler indicates Failure, which is fine, and then I have open the looping thing to make the pressure go up. It did go up because the boiler started working again but the pressure indicator is still stuck at 0.
Can someone explain me why the indicator is always at 0 ? Is it broken ? Is there something stuck in the pipes ?
(Note that 5 days ago I had a new shower installed in my bathroom and some plumbing work was done in there, not sure if that can help debugging the situation)
Here's the bottom of the boiler, with the meter:
