How to Install Short Dispenser Door Retaining Pin WPY912679 in a Whirlpool Dishwasher
Quick answer: Open the dishwasher door, pull the old pin out of the detergent dispenser cover hinge, align the cover with the dispenser body, press the new WPY912679 pin fully into the hinge bore, then check that the cover pivots and latches.
The short dispenser door retaining pin WPY912679 is a small steel pin that acts as the hinge for the detergent dispenser cover on Whirlpool dishwashers such as the DU2000W, CDU600V, CDU250B and DW700W. The cover pivots on this pin every cycle when the dispenser releases detergent into the tub. When the pin walks out or breaks, the cover falls off or hangs crooked and the dispenser can no longer hold detergent for the main wash.
This is one of the simplest parts to replace inside a dishwasher. The work is done from the inside of the open door with the dispenser still mounted in the inner door panel, so the door and outer panel stay in place. This guide covers how to seat the pin correctly, how to confirm the cover pivots freely and what to check before the next cycle.

- Unplug the dishwasher or switch off its breaker before working inside the door, even though this repair does not touch wiring.
- Shut off the water supply valve under the sink so the inlet cannot open while you work.
- Wear work gloves. The dispenser hinge slots and inner door edges are sharp.
- Let the tub cool and dry after a recent cycle so the inner door is not hot or slippery.
Tools and Parts You Need
- Needle-nose pliers
- Small flat-blade screwdriver
- Flashlight or headlamp
- Work gloves
- Small magnet on a stick for dropped pin pieces
- Clean cloth
Step-by-Step Installation
- Open the door and find the dispenser Pull the door fully open and slide out the lower rack for clear access to the detergent dispenser in the inner door panel. Locate the cover hinge along one edge of the detergent cup.
- Remove the old pin or its fragments Grip any exposed end of the old pin with needle-nose pliers and pull it straight out, or nudge a stubborn pin from the opposite side with the screwdriver. Sweep the tub bottom and filter area with a magnet for dropped pieces.
- Inspect the cover and dispenser body Check the hinge ears on the cover and the matching bores on the dispenser. A cracked ear or an oval, worn bore will not hold the new pin, and you may also need a cover or dispenser assembly.
- Clean the hinge bore Wipe detergent residue and hard water scale out of the hinge area with a damp cloth. Dried detergent cake is often why the old pin bound up and sheared.
- Align the cover Hold the detergent cover so its hinge ears line up with the dispenser bores. The cover should sit flat against the dispenser face with the latch tab facing the release mechanism.
- Insert the new pin Push WPY912679 into the hinge bore until the head seats against the hinge ear. It should go in with firm finger pressure; use pliers to finish seating it, but never hammer it.
- Check the pivot Swing the cover open and closed several times. It should pivot freely with no side-to-side wobble and snap shut when pressed against the latch.
- Restore power and run a test Reconnect power and open the water valve. Close the cover on a little detergent, run a short cycle and confirm the cup is empty when it ends.
Fit Checks Before You Call the Job Done
- The pin head sits flush against the hinge ear and does not stick out into the path of the cover.
- The cover pivots through its full arc without rubbing the dispenser body.
- The latch tab engages the release mechanism and holds under light finger pressure.
- There is no fore-and-aft play in the cover that could let the pin work loose.
- The pin cannot be pulled back out by hand once seated.
Common Mistakes to Avoid
Installing the pin with the cover out of alignment If the cover ears are not centered on the bores the pin goes in crooked and the cover binds. Line everything up first, then push the pin.
Forcing a pin into a cracked bore A split hinge bore will not grip the pin. If you see a crack, replace the cover or dispenser instead of hoping the pin stays put.
Leaving old pin fragments in the tub Steel fragments in the sump can jam the drain impeller. Recover every piece before running a cycle.
Confusing this short pin with a longer hinge pin WPY912679 is the short pin. A longer pin protrudes and can interfere with the cover release. Match the length to the old pin.
Skipping the pivot test A cover that looks right can still fail to open in the cycle. Work it open and closed by hand before closing the door.
Troubleshooting After Installation
Cover falls off again after a few cycles The bore is worn or the pin was not fully seated. Reseat the pin; if it still walks out, replace the dispenser cover.
Cover will not snap shut The cover is on backwards or the latch tab is not reaching the release. Remove the pin, flip the cover and reinstall.
Detergent stays in the cup after the cycle The cover is binding. Clear detergent buildup around the hinge and confirm the cover swings freely by hand.
Cover opens too early during the prewash The cover sits too high on the pin for the latch to hold. Confirm the pin is pushed all the way in so the cover rests flat.
Care Tips After the Repair
- Wipe the dispenser and hinge area monthly so detergent cake does not build up around the pin.
- Do not overfill the detergent cup; excess powder packs into the hinge and stiffens the pivot.
- Use rinse aid and an occasional dishwasher cleaner to limit scale on the inner door.
- Check the cover pivot whenever you clean the filter so a loosening pin is caught early.

Frequently Asked Questions
Do I need to remove the dishwasher door to replace this pin?
No. The pin is installed from inside the open door with the dispenser still mounted. Only a rack needs to slide out of the way.
Will WPY912679 fit my model?
It is listed for Whirlpool, Maytag and Jenn-Air dishwashers including DU2000W, CDU600V, DWU9906BAE and JDB3610BWX. Confirm your model number on the rating plate at the door edge.
What if the pin goes in but the cover still wobbles?
Wobble means the hinge ears or bores are worn. The pin is fine; the cover or dispenser body needs replacement.
Can I use a nail or generic pin instead?
A pin of the wrong diameter will fall out or crack the plastic bore. Use the correct part so the cover pivots and latches as designed.
