1. I researched "OE" code meaning on internet.
2. I found Youtube video how to repair, step by step, https://www.youtube.com/watch?v=LZY2kvSYQLY (was able to repair without disconnecting electrical hook-up or drain hose.)
3. Next I found this wonderful site to purchase the part.Part arrived in 2 days.
4.Unscrewed dishwasher from counter .Lowered the front legs.Disconnect water hose on front. Pulled dishwasher out. Removed left panel. Inserted new part. The hose clamps can be a little tricky.
5.Installed the part. Total job, 15- 20 minutes.It will take 30 minutes if your really slow.
6. My wife & I are happy again with clean dishes!
