I went to Sears to see if they had replacement parts. They said I'd have to order it. They said it would be 80 bucks.
Since I got the part number from Sears I went online to see if I can find a cheaper alternative. I found Appliance Parts Pro.com and they have the part for half of what Sears had it. I installed it myself and now the dishwasher is working again. All is happy.
