How to Install Upper Wheel Assembly WP99003148 in a Whirlpool Dishwasher

Quick answer: Extend the upper rack, open the front rail stops, and lift the rack out. Note where the failed wheel sits, pry it off its mount, and press WP99003148 on until the clip snaps. Reinsert the rack into both rails at once, close the stops, and roll it to confirm smooth, level travel.

Upper wheel assembly WP99003148 is a replacement roller for the upper dishrack in Whirlpool-built dishwashers, including Amana and Jenn-Air models such as ADB1500AWB, ADB2200AWS, and JDB1080AWQ. The upper rack in these machines rides on wheels that travel inside side rails attached to the tub wall. The wheel both carries the rack and keeps it centered in the rail, so when it cracks, flattens, or seizes, the rack drags, tilts, and can jam partway out with a full load of glasses.

There is no manufacturer description on file for this specific number, so treat it as a standard upper rack wheel and confirm its mounting position against the parts diagram for your model before you start. Some racks use the same wheel at every corner; others use distinct front and rear wheels, and rack adjusters can carry their own rollers. Once you have matched the position, the job itself is simple: release the rack from its rails, swap the wheel, and put the rack back.

⚠️ Safety First
  • Let the dishwasher cool before touching the upper rack or rails.
  • Wear gloves to protect against sharp rack wire and rail edges.
  • Hold the upper rack securely while releasing the rail stops so it cannot drop onto the lower rack or spray arm.
  • Pry away from your body and keep fingers clear of the clip when it snaps.
  • Do not operate the dishwasher with an upper wheel missing.

Tools and Parts You Need

  • Upper wheel assembly WP99003148 (confirm quantity against your parts diagram)
  • Flat-blade screwdriver

Step-by-Step Installation

  1. Confirm the wheel position Pull the upper rack out and compare WP99003148 with the wheel you plan to replace. Match diameter, clip style, and mounting location so you are installing it in the correct spot.
  2. Release the rail stops At the front of each side rail, open the stop tab or lever that keeps the rack from rolling out. Hold the rack while you do this.
  3. Remove the upper rack Roll the rack forward until its wheels leave the rails, lift it clear, and set it on a towel with the wheel side up.
  4. Inspect and clean Spin every wheel on the rack and look at the rails inside the tub. Wipe out scale or debris from the rail channels with a vinegar-dampened cloth.
  5. Pry off the failed wheel Work the screwdriver blade behind the wheel hub where it clips to the rack or adjuster and lever it off. Pull any broken plastic out with pliers.
  6. Snap on WP99003148 Orient the new wheel exactly as the old one sat, press the clip onto the mount until it clicks, then tug and spin it to confirm it is secure and free-turning.
  7. Reinstall the rack Keep the rack level and guide the rear wheels into both rails simultaneously. Push it in fully and lock the front rail stops.
  8. Verify travel Roll the rack in and out several times. It should glide without dragging, stop at the rail ends, and stay level with the door open.

Fit Checks Before You Call the Job Done

  • The wheel snaps on firmly and cannot be pulled off by hand.
  • The wheel spins freely and sits centered in the rail channel.

  • The rail stops are locked and hold the rack at the front.
  • Your model is among those listed, such as ADB1200AWS, ADB3500AWB, or JDB1080AWS1.

Common Mistakes to Avoid

Assuming all upper wheels are identical Some racks use different wheels at front and rear, or on the adjuster. Compare WP99003148 with the old wheel before prying anything off.

Leaving the rack in the rails while working The wheel cannot be pressed on properly inside the rail. Remove the rack first.

Reinstalling with dirty rails Grit in the rail channel is what wore out the old wheel. Clean the rails or the new one will follow.

Not locking the rail stops An unlocked upper rack can roll out and drop onto the open door under load.

Forcing the rack in crooked Feeding one side before the other twists the rack and can pop the new wheel out of the rail.

Troubleshooting After Installation

New wheel will not click on The mount may be scaled or you are on the wrong position. Clean the mount and compare the clip shape with the wheel you removed.

Rack still tilts after replacement Another wheel is worn, or the rack adjuster on one side is set differently. Check all wheels and match adjuster height on both sides.

Rack drags or squeaks in the rail Scale or food debris is in the rail channel. Remove the rack and clean the rails thoroughly.

Wheel pops out of the rail The rack was inserted unevenly or a rail is bent. Reinsert both sides together and inspect the rail for damage.

Care Tips After the Repair

  • Clean the side rails whenever you notice the upper rack starting to drag.
  • Keep heavy pots and pans in the lower rack to spare the upper wheels.
  • Pull the upper rack straight out, not at an angle, to avoid side-loading the wheels.
  • Inspect wheels for hairline cracks during regular filter cleaning.
  • Replace worn wheels promptly; a dragging rack wears the rails too.
