Make sure the clear bin is removed, then just undo the 3 torx screws and the whole top handle pulls out, bin rod with it
That's as far as you can get I think, hot water at a good pressure and lots of swirling and banging sorts the rest out. DC14 you can remove 8 torx screws, take the cyclone top off and there's a big seal there. Don't know of one on the 07.
