Product Description

Wax Motor for Detergent Cup Actuation Specifications

This is a dishwasher wax motor actuator that opens the dispenser cover to dispense dishwashing detergent and rinse aid during the wash cycle in your dishwasher. This is an authentic OEM part from the genuine manufacturer. It is a little over 2 inches long, and mostly red in colour. Disconnect power from your appliance because electrical wires will be exposed during repair. The wax motor is held in place by two tabs for easy release. Once you have gained access to the actuator, simply separate the two tabs and replace the part. This part is sold separately.

Detergent door wouldn't open
I used a voltmeter to see if 120 volts was present at the right time in the cycle; it was, so the actuator was the likely culprit. I ordered one on a Monday afternoon about 2:30, and it appeared on my doorstep Tuesday, shortly after noon! It took less than 15 minutes to replace the actuator - removing the 7 Phillips-head screws, lifting the panel, popping out the upper actuator, removing the two wires, putting them on the new actuator, popping it in and putting the panel back on. Worked like a charm. Happy wife . . .

Detergent Door not opening
Replaced wax motor. Since the latch grommet seal was nearby I replaced that also. That seal can cause significant door leaks and I had replaced it 5 years ago. It is easier to take the entire assembly off of the door and clean it. Be careful not to break the plastic linkages. To test the repair, you must let the dishwasher go through the entire wash cycle. Simply advancing the timer won't test it as the motor takes 1-2 minutes to fully extend and open the door. The door opens on fill number 3 of 4.

Soap dispenser does not open
After checking out the mechanism, I realized that the wax motor which operates the dispenser was no longer working. I conatacted Part select and on the second day, on a Saturday, Fedex delivered the little wax motor. I simply separated the front panel with the inside panel with 7 screws and a 1/4 inch nut driver. I slipped out the old wax motor, unclipped the two wires and slipped in the new motor. Attached the wires and put the panels back togehter. Voila, the dispenser works perfectly.
Total time, 15 minutes.

Door would not open to release detergent.
I removed the inside panel and discovered the actuator was caked with detergent and was not working. I replaced the cover and ordered a new motor. The new actuator arrived about a week later and I installed it in about two minutes.
No more problems.

The detergent cup would not open
I ordered the Wax Motor for the Detergent Cup. The install was simple. Unscrew about 7 or so torx screws and the lid opens up. Do not pull it off as it is attached to another device with wires. With the door laying down (fully open) there is enough room to pull the plastic door. The wax motor comes out when you bend two plastic built in clips. There are two wires attached. Remove them one by one and put them on the new wax motor while it is aligned in the same direction. Once the two wires are reinstalled, pop the motor back in it and make sure it is securely in place. Align the plastic inner portion of the door and screw the seven or so torx screws back in. Simple as that!

Soap Dispenser did NOT automatically open during wash cycle
My dishwasher has always done a fanastic job of cleaning, even dried on food without rinsing. Now it began leaving stains in the cups and the door to the machine was staining too. I was sure the whole thing would need to be replaced. My 'fix-it' husband found your internet site with a little better price on the little motor part needed and it came in just a couple days. The actual cleaning and scrubbing of the dishwasher's surfaces probably took longer than installing the part. It seems to be working great right now, and it's still 18 years old! Thanks, Carole

Dishes not getting clean, loud grinding noise during drain cycle, would not fill after first fill cycle and would not sanitize.
Since I did not orig. order a fill valve I bought one locally(at twice your price) and after installing it the dishwasher worked. I then continued to install the pump motor housing and the wax motor for the soap dispenser.
The dishwasher now works great, is quiet, the dishes are clean and sanitized.

Hello Anthony, thank you for your question. If the door isn't staying shut on the dispenser you will want to inspect the Detergent Dispenser Latch - White PartSelect Number: PS11747598,Dispenser Latch Spring PartSelect Number: PS11748490, Dispenser Door Switch Retainer PartSelect Number: PS11747595 and Wax Motor for Detergent Cup Actuation PartSelect Number: PS11746831 to determine which part has failed, or come apart from the assembly that holds the door closed. I hope this helps!
