I can't get my dishwasher out from under the cabinet. I took out the 2 screws on the top. It jiggles and wiggles, but won't come out. It's an old Whirlpool. Any suggestions?

There should be an access panel on the bottom where you can access the water supply and the electrical connections. These could be holding it in place. Safety first be sure to shut off the water and power to dishwasher before attempting removal. Also make sure the front legs of the dishwasher aren't catching anything like raised flooring material or anything else. If you haven't unhooked your electric and water supply and are uncomfortable doing it please consult a pro. Hope this helps and good luck.

Some times they screw in through the sides also. Check on the edges where the door closes for a small cap.
There could be a screw there also.
