I first ordered a replacement gasket from Amazon.com because it was less than half the price with free 2-day shipping. But when I received that gasket, it was much too thick for my dishwasher even though the part number was correct. It made it impossible to latch the dishwasher. I then ordered the gasket from AppliancePartsPro.com. Their gasket fit perfectly. The installation was very easy, just pull off the old one and push in the new one.
