I goggled a couple appliance parts companies; the first wanted to sell stuff before getting to the part I needed.
Thankfully, I found AppliancePartsPROS.com and was helped immediately. I ordered the short bottom seal for the GE dishwasher on 3/26/2015.It was sent by FedEx on 3/27/2015, it was received on 3/30/2015 and I installed it on 3/30/2015. I started the dishwasher and was very happy with the results. The best part of this order was that the "seal" cost $47.24 including shipping. Thanks again to Appliance Parts Pros and the lady that filled the order.
