boiler problem

[jojo33]

Hi, can anyone help me please. I have a worcester greenstar 24i junior boiler. I noticed a few days ago the pressure had dropped to around 0.4. I have put the plastic key in, and turned the white valve next to it, to raise the pressure, however it didn't work. water immediately came out, and the pressure did not raise at all. I have tried this several times, with no affect. I turned the heating off completely last night, as I was told it is dangerous to be running so low, and when I turned heating back on this morning, the pressure has dropped to 0. Does anyone know what I should do? Any help would be appreciated

The key needs to be inserted so that the thin side of the handle is facing the front of the boiler and it needs to be fully inserted. You then need to turn it 90 degrees (So that the fat part of the handle faces the front of the boiler) You can now open the water valve and watch the needle on the pressure gauge rise to around 1 - 11/2 bar. Turn water off and then reverse process for the removal of the key.

Thank you for your help. I'm not sure if I can figure out turning the water off, but I will have a good try

Its the small white square nut next to where the key is inserted. If you open it (Anti clockwise) and water leaks from the key, it means that the key is not properly inserted and you will need to try again. To turn the water off, all you have to do is turn the small square valve in a clocwise direction until the water stops.
Good luck

While you are filling it flick the gauge at the same time as they have a habit of sticking then jumping a bit.

try a spot of grease on the key as well

Well.. I did it! yes I inserted key properly this time, and yes the pressure went up but just now I realised it had dropped below 1 again, so I did it again.. and something went horribly wrong the gauge went up nicely like before, and when i got 1.3 I turned it off but.. all of a sudden water started gushing out of the key bit.. my kitchen is flooded It didn't seem to matter how or what I did, the water kept coming, tried to turn valve off, nothing worked! I have now managed to stop the water but the pressure is now above 2 ;( far too high.. what do I do now?? any help please as I'm seriusly debating wether to throw it through window

pressure is rising...now above 3

Is the boiler running now? Pressure will rise when it operation as the water gets hot.

Jojo the pressure will continue to rise if the filling tap isn't fully off, but a pressure release valve will open and discharge water to the outside once over 3 bar.
To give yourself breathing and thinking time, turn off the house stopcock for a bit.....
Once stable, reduce pressure from the boiler via a radiator bleed valve - you'll have to shift a few pints though so be patient.

ok thank you guys for your help. I have called a plumber as the pressure reducing valve is inside the boiler. I tried to turn valve off fully but it just starts leaking water again. The plumber said on fone he thinks there is an installation fault, as water shouldn't come in house? He's going to reset the whole thing for me, as water is now coming out of the front of the boiler. Hopefully no damage done! thank you

 

[Burnerman]

Jeez what a nightmare. Please post back with the findings?

will do he's on his way now.. fingers crossed!

 

[jojo33]

well, he has been, fixed the problem for me, showed me where the pressure reducing valve was, and that's all it took, to reduce pressure, however he was appalled with the installation of the boiler, the quality of the work, and the work that should have been done, but wasn't, and the price I was charged, and is writing a report for me, seems I was well and truly knocked. live and learn however I have found a good plumber now, and he only charged me £20! Thanks guys for your help
