I followed steps from video provided from appliance parts pro. It is truly help. It’s the best video from all over in the internet (I searched online all over trying to find a guide video, this is the best and easy to follow)
Best of all, parts I ordered arrived in less than 24 hrs. Amazed! I ordered them at 3 pm and it arrived at noon next day with 2-3 days shipping option. Then I spent 2 hrs to fix. Now my dishwasher works great , no unusual annoying noise any more. Thanks
