Located the part number on the broken plastic piece. It took me like 2 hours to realize that every part had numbers molded in. Plugged the numbers in and "BOOM" there it is o my screen. Ordered the parts, they got here in less than 2 days. Opened it and said, "These are not like those." But I read the instructions, installed it easily, and now I have an improved dishwasher! I can take care of my wifely duties much easier.
