Radiator not heating

Barack Obama

Lads - I've a radiator in the box room upstairs that's not heating at all. All others in the house are fine. I've searched through the threads on here and gone through these steps -
1. Open both valves fully. Closes and opened them a few times.
2. Bled the radiator - about 2 litres of clear water came out.
.3 Switched off all other rads in the house while heating was on.

None of this worked. One thing that I noticed with all of the other rads off was that the pipe to valve A (in attached pic) got hot but nothing entered the rad. I then blen the rad again and could feel heat up the left side of the rad and then across the top to the bleed tap.

I'm stumped . Any advice greatly appreciated!!

Blocked rad I'd say, you could take it down and try flushing it out with a hose.

Hi barach
Could be 1, Valve ceased or 2.Sludge in radiator. Firstly close both valves take of rad and flush it out with a hose. So the is ok.
secondly get basin to catch water. Open each valve slightly and see are you getting water. This will also test if valves are ok,

One shot on kill

id say wash the rad out take it off and clean it with hose as said before

close both valves
disconect rad from valves block holes with fingers and bbring rad out side dont open the blead screw this will help keep water in rad till you get youe finger over it
wash rad out half fill with water and shake it hard repeat till clean
open both valves ensure water is coming out one at a time obviously
replace rad and blead only blead when heating is out (pump off)
