The pressure loss was originally over about two hours then it got even faster. The pressure never rises when it's turned on. I started it (repressrised) at 1.5 and it just drops. The water just shoots out of the overflow.
Worcester Combi system won't keep pressure up and water is escaping from the overflow!!! I repressurised it and got it working for a bit but it gradually loses pressure again. Also I don't understand the reset buton, it wont depress? Does it need a key, it's got a cross shape on it?
Please...
It's a 280. I don't have a manual for it. Is the reset button on the main control panel? at what point would I do that? just after I had re pressurised? I turned off the power when I repressurised it, should I have done that?
Thanks for your help
My combi wouldn't start because I bled the radiators and the pressure went too low. Someone on the forum kindly explained about the filling loop and i got the pressure back. However, when I tried to start it back up again it doesn't heat up, water escapes from the overflow and the pressure has...
Can anyone help please? The combi heating system was working fine until I bled the radiators. One of them was completely cold so it needed a lot. Could the change in pressure have caused the problem? It's now below 1. If so how do I repressurise it?
Many Thanks
