Worcester-Bosch 240 Combi Boiler - Pressure help

alba37

Can anyone advise what to do to get water in to re-pressurise this old boiler, please?







TIA

Not sure other than to suggest youtube it or download the instructions and see if its in there.

Well, it looks like there are two taps there.
Start with the red one perhaps and open it a little to see what happens.
If that fails, get a screwdriver and try the other (silver) one

My plumber is coming 'mid morning' - I can ask him if you like?

open the valves on either end of the silver braided hose, until the green dial on the right is at about 1.5. looks like the one on the right has lost its plastic knob so will need a set of pliers cant see the other one so may be the same or need a screw driver
Do you know why the pressure has dropped to zero.
You may have to bleed the radiators too and then top up again as you go.
If the pressure won't hold then you have aleak in the system somewhere.
Don't touch the red valve that's the bypass balancing valve, it might even be redundant now depending on your CH system.

Thanks everyone.

My son and his girlfriend just bought the very old flat with this in it. (Young couple, first flat) They will be getting it replaced when they can, but it was sold with a working boiler and heating (if we can work out how to get it working!) I know how to bleed radiators, and have repressurised my own boiler before, but this had me stumped. I couldn't find anything similar on You Tube or Google.

I'll have to wait till we go back over now, but I am pretty sure I couldn't find any way to open on either side of the hose.... there was a small screw on the floor nearby that fitted into something. I will mark the part in a photo. They aren't moving in right away... thankfully!

Sorry, I was out this morning, but any suggestions or help at all would be appreciated.

The screw goes where you think it does but it would of held a handle on it to be able to turn and allow you to top the pressure up.

You will either need to turn the brass bit with a pair of grips or have the filling loop replaced.

We have exactly the same boiler. Its around 24 years old and worth keeping going, according to our plumber. The little red needle indicates what the pressure should be set to. You top up until the white needle is in line with it. That is, once you've managed to turn the bit where the handle should be.

It is a good boiler but has to be 25+ and Worcester made a lot of the parts obsolete a couple of years back along with the 280 and 350 models.

Have a good check round first that there aren't any open drain off valves anywhere in the system at radiators or the likes first, before commencing filling.
Also would probably be worth getting a tube of inhibitor and sticking it in too.

Anew filling loop is only a few quid, get one from screwfix or similar. You will probably have to turn off the water to fit it though.
