Worchester Boiler noisy ?pipes? and gurgling radiators

[LisaDIYdummy]

I seem to have a few issues at the moment with my heating system.

I have very noisy pipes and the pressure on my combi boiler is 0.

I have a Worchester greenstar 25si/30si (Not sure which) the pressure on here is 0 and I cant find my manual.

When I run the hot water for a bath - and it is stopped the system makes a very loud humming sound, this is stopped when I run the cold tap or flush the toilet. It sometimes makes this noise when i flush the toilet without running water anywhere else. The noise seems to be mainly upstairs but the combi is downstairs.

Also a couple of radiators are making gurgling noises when the heating system starts in the morning. I have just checked and one upstairs is a little colder than the rest.

My first choice is to bleed my radiators and hope that sorts it out. Is it likely that the radiator bleed will sort out these problems or is it more likely a plummer's job?

Any other suggestions very thankfully received as i have no idea

you need to top up the water pressure asap

i have found the key and followed the manual but the pressure is not going up

You insert the key, lock it, then turn the valve to its right to let water in...I think there's info in the FAQ's on this one.

Typical, i have topped up the pressure on my boiler to 1.5 (middle of green) and a tap upstairs wont shut off.

I was told that a leaky tap can cause pressure to drop in the boiler - do you think this could be the culprit of low pressure in the boiler in the first place?

Also it is an old tap without a pop open top to change the washer and it wont open half way down.

Suggestions? I have turned the water off at the mains.

Is it worth lowering the pressure again?
