Carol,
WMs usually have Hot & Cold water - a drain and mains power.
Mains power on simple plug and socket - Water connectors have little taps on the pipes and may be unscrewed by hand (or wrap a cloth around for extra grip) The drain is on a bent rubber or plastic pipe that simply drops vertically into the open drain pipe, just lift it out.
You will only get a few drips on the floor providing you turn those little taps off - quarter turn.
When you lay the drain pipe on the floor some foul water will come out but not much.
A strong child can do it.
