The right hand nylon link broke & the door would fall open with the spring tension gone

remove the bottom plate with a nut driver and back off on the front leg adjusters. Slide out the dishwasher approx 8-10 inches and remove the broken link. The new one goes on easily. Look at the opposite side if in doubt as to how to attach. Slide the unit back in and tighten the leg adjusters until the unit is secure. reattach the lower front panel which hides the leg adjusters, etc. You're done!
