Oh dear. Suggest you use his bed as dirty washing up storage. Don't cook him any lunch either.
If you can slide the machine(s) out far enough to see round the back but leaving it/them connected, I would dry everything off, in particular the pipes, then turn the water back on. If you can't see anything, run your finger along the underside of the pipe from the back of the washing machine, then to the machine tap then along the plumbing. You'll soon be able to feel a couple of drops of water; it's the way I check my compression joints when plumbing if I can't see them well enough.
It would be fairly unlikely (though not impossible) for the copper or its joints to fail. Suspect the hose itself, the hose connections at either end (they both screw on and each has a large rubber washer which might have died or got damaged) and the tap valve.
Is there any possibility it's the drain side (was either machine running over night or before you noticed the leak. Sometimes a bit of crud in the u- trap can cause it to bubble back out of the standpipe - you might tell if you can see if the water looks clean or dirty.
If you are able to start the machine(s) with it out, and have a torch handy, all should become clear.
If it's the hose, they are standard (varying in length) so easy to get.
Don't know what else to suggest, but that's where I'd start.
Let us know what you find, or if I'm off teh mark, I apologise in adavnce, my eyes are falling out of my head (up till 5am rebuilding my email and antispam servers).
