Pressure very low on our Combi 30 HE

Anonymous user 03/03/2024 - 3.16 PM

Hi, After bleeding our radiators, the pressure gauge on our Combi 30 HE is close to 0. I was wondering if someone could tell me what I would have to do to up the pressure in the boiler. I have attached a photo of the underside of the boiler, showing all the pipes etc.. Any help would be much appreciated. Miles

Are you a tradesperson and able to answer this question?

There should be two pressure valves located beneath the combi to allow you to manually raise up the pressure, but don't allow the gauge to rise too high if it comes out of the red while turning. Turn both gauges inwards so both thumbs face towards one another at same time while paying close attention as you notice gauge dial rising on display. Just allow display dial to come out of the red to reach roughly 5-10 mm into the grey area of display. Hope that helps

Hi, did gauge rise at any point whilst filling system? If not pressure gauge could be blocked. Pressure vessel could need recharging? All are posSible. Hope it helps
