Product review (5 stars): Works well.
Installed in Frigidaire DW M# PLD2855RFC1.  Exact fit.  Old unit leaked water from impeller housing.  Hint: be sure to remove the screen, pump cover, and ball check valve from inside tub prior to inserting the unit. This make seating the unit into the pump cavity much easier and puts less force on the nose end o-ring gasket, helping to ensure the gasket is not forced out of alignment. Also recommend using a small amount of silicone grease on both o-rings. (suggestion:  while the DW is out of the cabinet you may want to consider adding a sound dampening panel to the inside to the cabinet to further reduce noise.  Overall it's a simple to medium level DIY task.  Enjoy.
