The Whirlpool WP3374343 is an important but hidden component in your dishwasher. A spring located inside your dishwasher door's hinge assembly provides this unseen assistance. It provides continuous tension, which helps the door operate smoothly through balancing the door's weight.The spring keeps the dishwasher door level and stops it from shutting too forcefully when you open it. This deliberate movement lessens strain on your back and preserves the hinges. The door may sag, swing unevenly, or even slam shut with too much power if the spring is broken. Replacing a worn-out spring with the WP3374343 ensures the smooth operation of your dishwasher door, promoting safe and comfortable use for years to come.
