If the washer is less than a year old then it should be under warranty. Follow the directions in the owner's manual to schedule service. Here's a link for the owner's manual in case you need it: searspartsdirect.com/partsdirect/user-manuals/mhw3505fw0-maytag-parts-manual
. If the washer isn't under warranty, you can likely open the door by unplugging the washer and removing the top panel then pulling the manual release tab at the bottom of the door lock on the inside of the front washer panel. The manual release is a round tab that protrudes below the door lock assembly. Be careful as you reach down into the washer cabinet because metal cabinet edges are sharp. Pull the tab down and then pull open the door. Use a helper if necessary. Post more details if you need additional help.
