I'm not plumber but since no answers yet I'll throw something out and maybe folks who actually know what they are doing will tell you the right way
2 things to consider, water in and drain water out
if you are looking for something that is hooked up all the time would need to truely plumb things, cut existing pipes and add T's to the lines, you would need to know what size and type of pipes you have already to get adaptors t fit from them to the washer hookup.
If you are looking for something that you hook up each time you want to wash, you will want a hose that fits from the faucet to the hose on the back of the washer (on my washer there is are 2 fittings, one for hot and one for cold, I would see no reason that you could not just hook one line in and choose your water temp with the knobs on your sink. Another thing you can do is to fill with buckets, or if you are willing to wait with the washer then you can fill with any type of hose that fits on your faucet and you stick that hose into the washer itself and when it fills up you turn off the water and remove the hose and listen for when the rinse cycle starts, you will have to fiddle with the washer settings and maybe advance it (i have to do that with mine with the rinse cycle, we fill ours with a garden hose but it is outside and in a spot that if it overfills the water just drains on the ground...can't let water be running all over the floor in an apt so be careful and don't get distracted)
drain water out, it's pretty powerful when it comes out so whatever you are draining into make sure the drain will handle the amount of water coming out of the machine. you have to somehow secure that pipe so that it doesn't flop around and end up on the floor, you could stay with it and hold it (probably not feasable, if you are having to stay with it to fill it, no big deal if you forget - no mess, you will just have an empty washer, but if the drain starts before you get to it you will have a big mess) you could make some type of support (don't know what you have but wire, boards, clamps anything solid might work)
okay probably no help at all but maybe someone who knows will see my crazy ideas and have to respond
