All that really needed to be replaced was the seal on the diverter shaft. The seal is in the sump. Unfortunately the seal cannot be purchased individually and you must buy a complete new sump. I purchased a new sump and a pump grommet. The pump grommet probably did not need to be replaced but given the amount of work it took to get to that point it didn’t make sense not to replace it. Using the video on the website for the sump replacement made the job was very easy once I got the dishwasher removed from the cabinet. The video really made everything much easier. Knowing which way to turn things and what little catch had to be released was very valuable. The job took me about 45 minutes to replace everything and have the dishwasher back in place. I had to replace the clamp on the pump hose as the video shows. You might want to be prepared with the clamp before you start the job. OneNote on tools, you will need a torx driver
