How to Install Soap Cup Door Latch and Gasket W10131752 in a Whirlpool Dishwasher

Quick answer: Unplug the dishwasher, remove the inner door panel screws and tilt the panel to reach the back of the detergent dispenser. Unclip the old cover latch, seat the new gasket in the dispenser groove, snap latch W10131752 into the housing so it catches the cover, then reassemble and test the cover.

The soap cup door latch and gasket W10131752 keep the detergent dispenser cover on a Whirlpool dishwasher closed and sealed until the cycle calls for detergent. The latch catches the cover lip; the gasket seals the cup so spray water cannot wash the detergent out early. A worn latch lets the cover flip open as soon as the door closes, and a hardened gasket lets water in, leaving a wet paste in the cup and dishes washed without soap.

Our fitment data lists this latch for 155 dishwasher models under Whirlpool and Maytag names. The dispenser is mounted through the inner door panel, so the repair means opening the door panel rather than touching plumbing. Plan for a careful hour if this is your first time inside a dishwasher door, and confirm your model number on the label at the door edge before ordering.

⚠️ Safety First
  • Unplug the dishwasher or turn off its breaker; the door contains the latch switch and console wiring.
  • Shut off the water supply under the sink if your model routes the fill hose near the door hinge.
  • Support the door while the inner panel screws are out so it cannot fall open.
  • Wear work gloves; stamped door edges are sharp.

Tools and Parts You Need

  • Phillips or Torx screwdriver to match your door screws
  • Small flat-blade screwdriver
  • Needle-nose pliers
  • Flashlight
  • Work gloves
  • Towel and a magnetic screw tray

Step-by-Step Installation

  1. Cut power and prepare Unplug the dishwasher or trip the breaker, pull the lower rack and wipe the detergent cup dry.
  2. Remove the inner panel screws Open the door fully and remove the screws around the inner panel edge and any along the console. Keep them sorted, as lengths often differ.
  3. Tilt the panel Close the door most of the way and tilt the inner panel back until the rear of the dispenser is exposed. Rest it on a towel and avoid straining the console harness.
  4. Release the old latch On the back of the dispenser, press the retaining tabs on the cover latch W10131752 and pull it free. Note which way the catch faces before it comes out.
  5. Replace the gasket Peel the old gasket out of the cup groove, clean the groove with a damp cloth and press the new gasket in evenly, starting at one corner and working around without stretching it.
  6. Fit the new latch Insert the new latch with the catch facing the cover lip and push until both tabs click. Work the release lever by hand to confirm it moves freely.
  7. Test the cover From the front, close the cover and check it locks with a firm click, then trigger the release lever and confirm it pops open.
  8. Reassemble and run a cycle Refit the inner panel, tighten the screws evenly, restore power and water, and run a short cycle with detergent to confirm the cup empties.

Fit Checks Before You Call the Job Done

  • The cover locks with a click and does not open when the door is closed firmly.
  • The gasket lies flat in its groove with no bulges or gaps at the corners.
  • The release lever moves freely and returns on its own.
  • The inner door panel is flush and the door seal is not pinched.
  • The cup is empty and dry after a test cycle.

Common Mistakes to Avoid

Stretching the gasket A stretched gasket ends up too long and bunches at the last corner. Press it in section by section without pulling.

Installing the latch backwards The catch must face the cover lip. Reversed, the cover will never lock.

Losing screws in the door cavity A dropped screw rattles inside the door and can pierce the insulation. Use a magnetic tray and a flashlight.

Skipping the manual test Test the latch from the front before the panel goes back on. Reopening the door twice doubles the job.

Troubleshooting After Installation

Cover still opens when the door closes Check that both latch tabs clicked into the housing and the cover lip is not cracked. A warped cover needs replacing.

Detergent turns to paste in the cup The gasket is not seated or the cup is cracked. Reseat the gasket and inspect the cup for hairline splits.

Cover never opens mid-cycle The release actuator or wax motor behind the dispenser is not moving. Check its connector and replace the actuator if it is dead.

Water on the floor after reassembly The door seal shifted when the panel was refitted. Loosen the screws, reseat the seal and retighten.

Care Tips After the Repair

  • Wipe the cup, cover and gasket after each week of use to remove dried detergent.
  • Load detergent only into a dry cup so the cover closes cleanly.
  • Do not slam the door; it stresses the latch and the cover hinge.
  • Inspect the gasket yearly and replace it if it is hard or cracked.

Frequently Asked Questions

Does the kit include the gasket?

Yes. The part W10131752 supplies the cover latch together with the cup gasket so both can be renewed in one job.

Can I fit the latch without opening the door?

On these models the latch tabs are on the back of the dispenser, so the inner panel has to come off.

Why is there still detergent in the cup after a cycle?

Either the cover did not open, or the spray arm is blocked and water is not reaching the cup. Check the latch release first, then the lower spray arm.

Will this fit my Maytag dishwasher?
