James S Brooklyn , NY December 04, 2015 A broken detergent cup for a white westinghouse dishwasher The best guide was relevant videos on You Tube. It demystifies the process. Unfortunately, there are no videos for this particular type of detergent cup, but you'll get a good general idea from the other brands. By all means, once you remove the lid, take a photo of the assembly before you take it apart. It will serve as a guide, as no diagram came with the part. The vendor's website has a picture, but you may want to have something on hand. I used a drill with screwdriver sets and an extension, due to cramped quarters around the dishwasher. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
