The detergent dispenser controls when and how much soap enters the wash cycle. It holds the detergent in a sealed compartment, then releases it at the correct point in the cycle by opening a spring-loaded door triggered by a wax motor or bi-metal actuator. When the actuator burns out, the spring breaks, or the door latch cracks, the dispenser door stays shut — detergent never enters the wash, dishes come out greasy and dirty, and the cycle completes with the soap pod or powder still sitting in the closed compartment. The WPW10224428 Whirlpool OEM Detergent Dispenser is the factory-specified replacement that restores timed, precise soap release on every cycle.

Pro Tip — Check the Door Latch and Wax Motor Before Replacing the Full Assembly:
Most detergent dispenser failures are caused by one of two things: a broken door latch/spring (the door won’t stay closed before the cycle, or won’t open during it) or a failed wax motor actuator (the door stays permanently shut because the trigger never fires). Before ordering, open the dispenser door manually and check if the spring snaps it shut with tension — if the spring is limp or broken, the latch mechanism has failed. Then run a cycle and listen for a click from the dispenser area at the main wash phase — no click means the wax motor has burned out. In both cases the full assembly replacement is the correct fix, as the actuator and latch are not sold separately for this model.

✓ Installation Notes
- Skill Level: Beginner to Intermediate — requires inner door panel removal
- Estimated Time: 20–40 minutes
- Key Steps: Disconnect power → Open dishwasher door fully and remove all screws around the inner door panel perimeter → Carefully separate inner panel from outer door shell → Disconnect the wax motor wire harness connector from the dispenser → Release the dispenser mounting clips or screws from the inner panel → Push dispenser out through the front of the door panel → Seat new dispenser from the front, secure clips or screws → Reconnect wax motor harness → Reassemble inner and outer door panels → Restore power and run a test cycle to confirm dispenser door opens at the correct time
- Safety: Always disconnect power before beginning. Do not force the dispenser out — release all clips before pulling. Confirm the wax motor harness connector is fully seated before reassembling the door panels.

✓ Frequently Asked Questions
Why is my detergent pod still in the dispenser after the cycle?
The dispenser door failed to open during the wash cycle. This is caused by a failed wax motor actuator (the trigger that fires the door open at the correct cycle point) or a broken door latch spring. In either case, the detergent never enters the wash and dishes come out dirty. Replacing the full dispenser assembly (WPW10224428) resolves both failure modes.
Is WPW10224428 the same as W10224428?
Yes — W10224428, 8565814, 8565816, W10195169, and WPW10224428VP are all superseded or cross-reference part numbers for the same Whirlpool dishwasher detergent dispenser. WPW10224428 is the current active OEM part number and is a direct replacement for all of these.
What is the Used option?
The Used option is a genuine Whirlpool OEM detergent dispenser pulled from a working appliance, inspected for door latch function, spring tension, and wax motor integrity. Ideal for older dishwashers where a new part may outlast the appliance.
