Drained system, took out pump, top valve was closed, bottom was only half open. Replaced both anyway, re-used same pump and system is all ok now. Thanks again

Looks like I'm going to have to drain it down again then :-( As it is the one on top i.e the one that is supposed to be letting water into the pump, could I have damaged the pump by running it dry? Thank you all for your input and help. Much appreciated.

well, upon checking the pump valves, one of them (the top one) is actually spinning freely (its a gate valve type one). Could this be a (THE) problem...?

the shaft moves freely when turning with a screwdriver, but it makes a horrible racket when turned on. By switching just the hw on as has been suggested, the boiler still turns itself off after a couple of minutes. And the direction of flow according to the pump is downwards (!) and the...

A lot of info there...! I undone the bleed screw as you have shown and all that happened was that it came out in my hand - no water or air - should there have been either?

Chris and others, I have done as suggested, moved the 3 way valve halfway and let it move back to auto again, I have closed the by-pass (well it was closed anyway) and I have bled air from the vent in the airing cupboard and all the rads. Since cleaning the system, the water coming out of...

By putting the valve to HW only do you mean slide the lever to manual? Yes there is a llink pipe between the flow and return in the airing cupboard - it has a gate valve (I think that's what it is - but without the red handle)

Thanks Chris There is indeed a vent point near the cylinder - this was the first thing I tried, it seemed to let a lot of air out. Now it is only letting water out...

Been reading a few of the posts in here and I think my problem is either my central heating pump (WILO GOLD) or my 3 way valve thingy (Danfoss). I drained the system, cleaned and re-filled because a couple of rads were not working. I have bled air from everywhere I can see, yet the boiler...
