I assume that you *are* using a proper plumbed-in washing machine tap -
and
not some adaptor which fits on a normal sink tap?

Yes, of course. It's a brass fitting which emerges from the floor. There is
another one for hot water which is no longer used.

In that case, it sounds as if either the rubber washer is missing, or
isn't
thick enough. You can sometimes get a situation where the annular threaded
part doesn't screw far enough onto the tap to compress the washer. In this
case, you need to fit an additional rubber washer - maybe by taking the
one
out of the old hose.

Thanks. I might just buy a couple of new hoses and see how that works out.
Another problem is that it was also leaking from the Y-piece connection,
