Maytag dishwasher door won't lock
I have a Maytag model MDB5601AWB dishwasher. The door stopped locking shut, so I have a wet floor at the end of each load. There is a metal latch that extrudes from the top tub side, and a plastic locking mechanism inside the door. I can see that when I depress the handle, the plastic lock mechanism springs open. And when I close the door, the mechanism springs closed, but it does not close on the metal latch for some reason. I can't see why it doesn't close, because the metal latch is obviously the reason the mechanism is springing closed, but it doesn't hook onto the latch.
Any suggestions? Thank you!
