Ok... Had a radiator taken off, system was drained off radiator put back on

but now heating and hot water wont work

I've search on the net and found this

Q. My boiler isn’t working – there is zero pressure showing on the gauge.

A. It could just be that there isn't any water or enough in the system.
There could have been a drain down or a radiator taken out previously
if you have just moved in or there could be a leak on the system somewhere.
You need to first refill the system - a combi has a filling key to do this
where the charging link assembly is - we can supply if you don't possess one.
A typical combi is a Worcester 24i which is detailed below – for particular
boilers refer to you handbook.
You remove the bottom panel to gain access to the filling loop assy.
The grey knob is supplied with the boiler in the hardware pack, insert the
bayonet end of the key into the corresponding cutouts in the filling loop
housing and twist to lock the key in place.
Turn the grey knob clockwise to stop filling and remove the filling key by
lining up the bayonet end of the key with the cutouts in the filling loop
housing and withdrawing the key.
The key has to be removed from the filling loop housing after the system
has been filled to prevent accidental filling and to comply with Byelaw 14
of the Water Byelaws Scheme.
Store the key in a safe place and replace the bottom panel.
If the boiler still doesn’t hold any pressure see below.

back to me....I've put the key thing in place turned it and nothing is happening.... am I missing something should I be doing something else?

when key is in, turn the grey knob next to it and you'll hear the watrer running into boiler, hopefully!
 
Thank you ...I looked for a grey knob there wasnt one ..but there is a small square plastic thing next to where the keygoes in....thought I have nothing to lose if i turn it.........and I've filled it to 1.5 :) and bled the radiators.. now fingers crossed I get heating and hot water

thanks so much
