We needed a new dishrack track and stopper. My husband used to order parts and make repairs but has some vision problems and told me I must take over. Our son suggested APP.com as he used your videos to install the dishwasher. I watched the video then ordered the two needed parts. When I couldn't get the stopper to snap in as shown on the video, I emailed APP. Jason very soon responded and checked to make sure I had the correct parts, and I did. He then said if the stopper was defective, the company would replace it. I compared it to the old one, and it looked fine. I just couldn't get the part to snap in. I could still CAREFULLY use the dishrack. After failing two more times to get the stopper in, I used the dishrack without it for over a month.. Then today I tried again and snapped it right in. I emailed Jason to share my success and to promise this positive review of your company. APP did your best, and thanks to your video and swift delivery of parts we still were able to use the dishwasher even though I was SLOW to install the stopper. Thanks to you, we saved a bundle of money.
