While I was moving my washing machine the input hose pulled out
of the fitment where it goes into the machine. Cue several dozens
of gallons of water over the kitchen floor... But now I can't get the
fitment back over the hose - it's one of those screw-on things that
holds the end of the hose against a rubber washer on the machine.
It must have got through the hole on the way out, but there's no
give on the fitment to let me push it back over the hose, and I
don't want to risk breaking anything by pushing too hard or
bashing it with anything... Any advice please?

(The machine is an AEG Lavamat Turbo washer-drier, if that helps).

thanks,
Andrew
