Drain Cycle Not Working

Removed the lower Front panel, removed the (2) hoses from the Pump Assembly, Removed the Plastic Sprayer Recirculating Tube, than removed the (6) screws that hold the pump assembly in the washer basin, removed the assembly from the unit.
Disassembled the pump unit (6) screws, removed and replaced the (2) water impellers and bottom seal, reassembled everything and all is well. This machine is 22 years old and my local parts supplier said that parts were no longer available for it because of its age, well I have news for him PartSelect.com has any part I need!
