Thanks The_Economist, my partner followed your instructions above & it seems to be working, guess we'll have to wait & see if the rads heat up now.

To check the pump, place an old towel or similar under it and then remove the silver screw in the middle.

Some water will dribble out and may be hot. Insert a flat bladed screwdriver, locate it into the slot you will feel, and try turning it.

It should turn freely. If not put a bit of force behind it to turn it. If it won't turn, then it's time for a new pump.

If it does turn it could mean there is an electrical fault in the pump if you cannot feel it vibrating and spinning. Sadly though even though a pump spins, it does not necessarily mean it is circulating properly.

Removing this silver screw will also bleed the pump of any air.

If you have a 3 port or 2 port valves, it/they should have been set to manually open whilst filling the system.

Thanks for all the help.
