Initially checked pump screen. It was clear. Then ordered a replacement pump from AppliancePartsPros.com. The pump arrived in 2 business days. Very simple part to replace. Just need to take your time and drain out all of the water from the filter holder before dropping the pump. The pump is held in by 4 screws. Disconnect the drain line from the old pump, unplug the electrical, and reverse. Anyone with basic skills can easily complete this and save a bunch of money. The hardest part of the job was moving the washer away from and then back to wall.
