Dishwasher will not run unless you push on the door. Latch does not seem to keep door closed enough to allow it to operate.
You will want to check the latch on the dishwasher and adjust it as necessary. If you pull the unit out a little from installation you should be able to adjust the latch forward or back. Make an adjustment and see if this corrects the issue. If not then you would need to replace the lock assembly in the door.
