To start with I checked the discharge line and looked for obstructions in the tub but didn't find anything that should have stopped the drain so I decided that it must be a pump problem. having already pulled the machine out and disconnected the discharge line I realized there wasn't much to do to replace the pump. I did a Google search for the make and model of washer and Appliance Parts Pro came up and they seemed to be the most accurate and easy to use so I ordered the pump and within a couple of days it arrived. It took me a total of about 45 minutes to an hour to remove the washer take off the old pump and replace it with the new pump. I ran a test cycle and everything worked great.
