How to Install Dispenser Latch Spring WPW10116816 in a Whirlpool Dishwasher
Quick answer: Unplug the dishwasher and remove the inner door panel screws to reach the back of the detergent dispenser. Unhook the old latch spring, hook new spring WPW10116816 between the latch lever and its anchor post so it pulls the latch closed, then refit the panel and run a cycle to confirm the cup opens.
The dispenser latch spring WPW10116816 is the small spring that returns the detergent cup latch on a Whirlpool dishwasher to its locked position. You load the cup, close the lid and the latch holds it shut until the timer or wax motor releases it mid-cycle. When this spring stretches or breaks, the lid will not stay closed, detergent spills into the tub before the wash starts, and dishes come out dirty or coated in film.
Our fitment data lists this spring for 43 dishwasher models under Whirlpool, Maytag and Jenn-Air names, mostly older machines with the mechanical dispenser mounted in the inner door panel. The manufacturer publishes no detailed description for this part, so the guidance below is based on how these dispensers are built: the spring is reached from the back of the inner door panel and simply hooks between the latch lever and a fixed post. Confirm your model number on the door edge label before ordering.

- Unplug the dishwasher or switch off its breaker before removing the inner door panel; the door houses the latch switch wiring.
- Support the door while the inner panel screws are out so it does not slam open under its own weight.
- Wear work gloves; the panel edges are sharp and the spring can snap back onto a finger.
- Keep track of every screw and clip, because the inner panel also holds the door seal in place.
Tools and Parts You Need
- Phillips or Torx screwdriver, depending on your door screws
- Needle-nose pliers
- Flashlight
- Work gloves
- Towel to protect the door finish
- Small magnetic tray for screws
Step-by-Step Installation
- Cut power and empty the door Unplug the dishwasher or trip its breaker, remove the lower rack and wipe the detergent cup dry so nothing drips into the door cavity.
- Remove the inner door panel screws Open the door fully and remove the screws around the perimeter of the inner panel. Some models also have screws behind the console, so check the top edge before pulling.
- Separate the panel Close the door partly, lift the outer panel or tilt the inner panel back until you can see the rear of the dispenser. Rest it on a towel and do not strain the console harness.
- Locate the latch mechanism On the back of the dispenser you will see the latch lever, the release actuator and the spring anchor post. Note where each spring end hooks before removing the old spring WPW10116816.
- Remove the old spring Unhook the spring with needle-nose pliers, freeing the latch lever end first so the lever does not fly forward. Check that the lever moves freely on its pivot.
- Install the new spring Hook one end of the new spring onto the anchor post and stretch the other end onto the latch lever. The spring should pull the latch toward the closed position.
- Test the latch by hand From the front, close the cup lid and confirm it clicks shut, then push the release actuator gently to confirm the lid pops open and the latch returns.
- Reassemble and run a cycle Refit the inner panel, tighten all screws evenly, restore power and run a short cycle with detergent to confirm the cup releases during the wash.
Fit Checks Before You Call the Job Done
- The cup lid clicks shut with firm resistance and stays closed when the door is slammed.
- The latch lever returns fully after the actuator releases it.
- The spring sits straight between its hooks with no kinks or twists.
- The inner door panel is flush and the door seal is not pinched.
- Detergent is gone from the cup after a test cycle.
Common Mistakes to Avoid
Removing the panel with the door open With the screws out, the door can drop hard. Keep it partly closed and supported while the panel comes off.
Hooking the spring to the wrong post There are several ribs and posts near the latch. On the wrong post the spring pulls the latch open instead of shut.
Overstretching the new spring Stretch only as far as needed to reach the hook. A spring pulled past its limit loses tension immediately.
Ignoring a worn latch lever If the plastic hook on the lever is rounded off, a new spring will not hold the lid. Replace the lever or dispenser at the same time.
Troubleshooting After Installation
Cup lid still pops open before the cycle Confirm the spring is on the correct post and the latch lever hook is not worn. Also check that the lid itself is not warped from heat.
Lid never opens during the wash The latch is now too tight or the release actuator is not moving. Check the actuator or wax motor and its wiring at the back of the dispenser.
Door leaks after reassembly The door seal was pinched or displaced when the inner panel went back. Loosen the screws, reseat the seal and retighten evenly.
Dishwasher does not start A door switch connector was disturbed while the panel was off. Reopen and reseat every connector on the latch assembly.
Care Tips After the Repair
- Wipe dried detergent off the cup and latch weekly so the mechanism does not gum up.
- Use fresh detergent; caked powder stops the lid from latching cleanly.
- Do not slam the door with the cup loaded.
- Check the cup opens fully after each cycle and replace the spring at the first sign of a loose lid.

Frequently Asked Questions
Can I replace the spring without removing the inner door panel?
On most of the compatible models the spring sits behind the dispenser, so the panel has to come off. A few dispensers allow access from the front once the cup cover is removed.
Why does the whole cup of detergent end up in the tub at the start?
With a weak latch spring the lid opens as soon as the door closes or water sprays it, dumping detergent during the prewash instead of the main wash.
Is this the same as the dispenser door spring?
No. This spring returns the latch lever. The lid hinge spring that pops the cover open is a separate part.
Will it fit my Maytag or Jenn-Air dishwasher?
This spring is listed for Whirlpool, Maytag and Jenn-Air models. Match your model number against the compatible list before ordering.
