The spring on the dishwasher door hinge controls the door's opening and closing, so the door doesn't drop open or slam shut. If the dishwasher door falls open quickly without any resistance, it's likely that at least one of the dishwasher door springs is broken. Replace both at the same time to ensure that the control tension is the same on both sides of the door.
Follow the instructions below for replacing the dishwasher door hinge assembly tension spring using a manufacturer-approved dishwasher part. Also see our other dishwasher repair guides for more repair help and to find the right parts.
These steps show how to replace the dishwasher door hinge tension spring on Kenmore, Whirlpool, KitchenAid, Maytag, JennAir and Amana dishwashers when the dishwasher door falls open too quickly.
