Kenmore dishwasher won't latch all the way

My Kenmore Quiet Wash Ultra Gaurd 3 Dishwasher will not close fully. I have to maintain pressure on the door for it to work. How can I fix or adjust the latch to make it stay fully closed?

grinch,
If your washer is less than a year old call a Sears tech for service so you do not void the warranty. Are there three numbers to the left of those posted?
