URGENT Worcester Heatslave 15/19 Oil Combi Boiler Pressure

[Klosblue]

My boiler pressure gauge is at zero so the boiler is not firing up. I thought I heard a small water leak in the wall near the boiler the other night, just before this happened, but the leak has now stopped.

I have been reading other posts to try to find a solution and I've hunted everywhere for the filling loop but can't find one. I don't have a hot water tank cupboard so it's not there, it's not hidden in the next kitchen unit, it isn't hidden anywhere I can see! I am absolutely freezing up here in sunny Scotland!!

Can anyone help please, I am a desperate female in need of being rescued. Thank you.

Hi.

Take the front panel off the boiler unit itself and see if you can see the filling loop in there. Will be a metal flexi hose with two tap handles, one either end.
Having said that if you heard water dripping before this happened there's more than likely another problem. The worst case the jacket has gone but then you would of seen water internally. Its more than likely the PRV has discharged, that happens when the valve is faulty or has stuck open or more likely in this case the pressure has got too high and opened up to dump the pressure. This could be down to vessel lost its charge, too little charge, diaphragm has perrished or the flexi to vessel has kinked/blocked.

Hi
Thanks for your reply.
I can see a metal flexi hose coming from a red box and going somewhere behind it but neither end has a tap handle.
As for the rest of what you say, I'm sorry but you've totally lost me! The water was from behind a wall and not the boiler and there's no water leakage in the boiler. I'm sorry for not understanding the rest but I don't know anything about boilers!

That red box is the expansion vessel or the burner casing (depending on which burner it is).
Can you take boiler casing off and send a picture of the unit? That might help me point you in the right direction.

Edit : You might need to take top panel off as well

You're a genius!! I eventually managed to get the top off and found the filling loop behind the boiler near some pipes. I think I know what to do now - press the button thing on one side of the loop until the pressure gauge comes up to 1 bar - is that right?

 

[SJB060685]

There should be two black quarter turn valves. Turn one fully open then the other until pressure is around 1 bar then turn both off.

Does it matter which one I turn fully open?
