Well I just had my pump replaced but cannot get the upstairs radiators to work. There is an air blockage somewhere in the system. So far I have bled all the radiators, bled the pump, bled the boiler too, and bled the upstairs manifolds. There was only a small amount of air. I have closed all the radiators downstairs and put the boiler to max in an attempt to push the air upstairs to be bled; this was only partially successful as the pipes near the hot water tank warmed up but still cold upstairs radiators.
The pump is set to high speed by the way.
Anyone have any ideas ?

it does sound like blockage somewhere,if the system is open vented then it could be where the coldfeed tees into the circulating pipework.are the upstairs radiator controlled by roomstat and a zonevalve?it could be the sychron motor in the valve.what colour is the water in the system?it might be needing a power flush.once you have resolved this problem,make sure the pump speed is set at the correct speed.

You say you had the pump replaced but don't seem to want to have the person that did it come back and finish the job.
Was the pump bad anyway? Usually, with a downstairs boiler, the upstairs radiators will work without a pump.
A blockage is serious (but highly unusual). The boiler can produce sufficient energy to destroy most of your house if built up behind a blockage then suddenly released through a rupture so act with caution.
Edit - I have seen a plumber working on a system where the pipes had air traps in them. What he did was get a bucket, remove the pipe from the radiator then open the valve into the bucket. The increased water flow gets the air out of the traps.

Make sure the valves either side of the pump are open. Turn the pump down to a lower setting and close downstairs rads a half turn. to push more heat upstairs. If no improvement turn rads down another half turn. Try to vent any air from pump. If none of this works, it is possible the pump has been fitted the wrong way around. Also check if there is an air bottle on the flow pipe near the hot water tank. It is a copper pipe about 4/ 6 inches long with an air vent on top.

The first thing I would do is make sure that there is nothing blocking the circulation of water through the system. this means you should check every water valve to make sure they are open. Once they are all open turn the boiler on and let it run for about 15 minutes then check the upstairs radiator. It's going to take a while to get hot water to the top, because the bottom radiators will continue to remove the heat from the water until they are warmed up. If this doesn't work then you have a blockage someplace restricting flow.
HOPE THIS HELPS☺

If there is not any air or water popping out the bleed valves then you definately've a difficulty with the stress. If the device is crammed by potential of a filling loop then you definately ought to fee up the stress to around a million bar.If the heating is an open vented device then the chilly feed pipe could be choked or the ball valve on the feed and growth tank has jammed.it ought to additionally be the pump this is combating the radiators from being bled.attempt switching the CH/HW off on the timer.

Was the pump fitted in the same direction, was it wired the right way round and did the sludge in the system have time to settle and dry out while the system was off? Did you do this yourself? If not, why have you not got the installer back?

May be the pump is not able to lift the weight of water the height needed. Also if you can try filling the pipes with water first.~~
