My Hotpoint Aquarius Washing Machine, has stopped spinning! I'd left the washing going whilst I was out, and when I got home, noticed that all the washing was still wet, I tried emptying it, and moving the drum by hand, and it wouldn't move, with a little force (maybe foolishly?) I've got the drum to move, but it seems to be moving without the slight resistance that was present when it was working correctly? I've looked on various websites, and there seems to be mention of the belt having come off, and the wearing down of 'carbon brushes'? If this is an easy thing to mend, then I'd be most grateful to avoid any expensive repair bills?
