KitchenAid

Bought a brand new Kitchenaid dishwasher from Sears in Ontario, OR. Paid $990 on Nov 17th. Didn't get it in until Nov 25th and we finally got someone to install Nov 30th,. It leaks down at the bottom the same day it was installed. Never did work right. Called the manager at Sears and he said he couldn't help us because we didn't buy the warranty. I thought local stores would take care of problems that happened immediately. Everybody else that I have bought appliances from have covered it locally. We need a response or we are going to dispute on our card and tell Sears to pick it up.
