Low water pressure problem Worcester 24i

[alexus87]

Hello, I have a problem with my boiler. A couple of days ago the heating stopped working,when i went to see what the problem is, one of the valves was leaking a little bit, so I bled one of the radiators(I dunno why I did that,but it worked). Unfortunately the next day, the boiler stopped working,and the pressure now is 0 bar. Whenever I turn the hot water on, I hear the spark, but after 2-3 attempts to ignite, it stops and the red light flashes. Could you tell me how I can fill the boiler again?so that the water pressure is ok? Somebody told me I need a key and that there is a slot at the bottom of it. I'll attach 2 pictures(actually 3) so that you guys can get an idea. Please if anybody has any idea let me know as it's freezing here.

Sounds like you need to put some water back in first.

If you look under boiler, there is a white plastic knob, which is the cold inlet.

Next to it is a hloe, where you need to fit the key. Its about 4" long and tee shapped. If you cant find it

have a look on top of boiler. When you do find it, insert into hole and turn clock-wise to engage it into place. then turn plastic knob anti-clockwise till

it fills to 1.5 bar, then go and vent all rads. Re=fill to 1.5 bar and run boiler.

thanks a lot guys. The key was so dirty it was grey like the cover-plate, so I overlooked it. Everything is working now. I did a trial run and it works, water pressure is 1bar and seems to be working fine, should i put in 0.5 bar more? Again, thanks a lot, my girlfriend is caribbean and she kept complaining that it was too cold and she couldn't sleep properly.

When the system is cold, charge it to 1.5 bar as said and vent. Re-charge to 1.5 and run the boiler.

You will have to get that leaking valve repaired or it will keep droping

presure, and cause further problems with the boiler.
