Is this the part that will keep the soap lid down?
Answer Hello Kristy. No, you will need to order 676413 for the latch kit.
Is there a diagram of how to install the spring in the soap dispencer door of a whirlpool model # du840cwdb4 dishwasher?
Answer Don, Instructions are not available for your repair, but heres an excerpt from the APP Repair Forum Posts, that should help you out. "If you're not sure which way the spring goes, remember that the spring should compress (coil) when the detergent door is closed, and uncoil when it snaps open. What I finally figured out to reassemble, that worked: 1) Put the spring and pin on the detergent door, with the spring coiled so the top side of the coils point back (toward the detergent cup) 2) Snap the pin back into its slots, with the spring's square center tab toward the matching base in the dishwasher door 3) GENTLY lift one side of the pin up again, so you have room to use a small screwdriver to push the free end of the spring into the detergent lid, then press the pin back in 4) Repeat (3) with the other side of the pin, and the other end of the spring.
