I used the instructional video from AppliancePartsPros.com that was EXCELLENT. I was able to install this sump without any help. I'm a mom of two that has no experience in this whatsoever. It was either try it or buy a new dishwasher. The video is so easy. I had my tablet next to me with each step. It took me about 3 hours but at the end I saved money and got a well functioning dishwasher. Thank you so much!!!
