Vented system radiator issue

I need some help please. Did some decorating, removed a radiator and closed both valves. No water leaks etc and heating worked fine the past three weeks. Today, installed the radiator back, and opened the feed valve to fill with water, but only a small amount filled. I forgot to put the heating off and I came on while I was trying to fill the radiator. Now all the upstairs radiators aren't filling up, as when bleed valve turned, nothing coming out. All downstairs are ok. When the heating comes on, the hot water pump makes a noise it never had before, open its bleed valve and no water. I've turned everything off now. I have a vented system, so tank in the roof, expansion tank in the room upstairs and boiler downstairs. Nothing to pressurise etc. I had done this before in my previous house, but it was a pressurised system so was pretty easy, but I can't work this out......any help out there. submitted by /u/Machendez [link] [comments]
