First I tried to lift the lid on the top of the washing machine. I eventually realized this model doesn't open up from the top. I removed two screws on the very bottom of the front panel of the washing machine. Then pulled gently downward to release the front panel from the two clips holding it in at the top. Once the front panle was removed, I found I could easily access the drain hose and disconnect it from the pump by loosening the clamp screw. (Be aware, there is still water in the hose and pump that will run out onto the floor; I had a bucket close by and tried to catch most of this water, but its somewhat futile.) There are two additional hose clips one underneath the tub, and one on the back panel of the washer that hold the hose away from other mechanical parts. Once the hose is freed from those clips it could be removed from the washer by feeding the hose out the back panel. The new hose was then inserted and fed down inside the washer, attached to the pump, tighten the hose clamp screw, clip the hose to the other two clamps so it is out of the way of other parts, reattached the front panel and you're done!
One other note about PartSelect.com...A few days after ordering my part, I had an "International Transaction Fee" show up on my debit card statement. I panicked thinking my card number had been stolen only to call my bank and find out PartSelect is based in Canada.
