How to Install Dishwasher Positioner Gray WP8539102 in a Whirlpool Dishwasher
Quick answer: Pull the rack out, locate the adjustable tine row pivot, pry the broken gray positioner off the rack wire, snap WP8539102 onto the same wire with its notches facing the tine row, then fold the row through each position to confirm it locks.
The gray positioner WP8539102 is the small plastic piece that lets an adjustable tine row on a Whirlpool dishwasher rack lock into different angles. Its notches catch the tine row wire so the row can stand fully upright for plates, lean back for bowls, or fold flat for a large pot. When the positioner cracks, the row will not stay put and drops flat the moment you load it. The part is listed for 814 models, mostly KitchenAid and Whirlpool racks such as KUDS03FSBL1 and KUDE48FXWH0, and it is sold as a single piece.
Nothing electrical or plumbing-related is involved. You will spend more time getting the rack onto the counter than doing the swap. What matters is orientation: the positioner has a definite front and back, and if you snap it on reversed, the notches face away from the row and the lock never engages. A manufacturer video exists for this part, but the steps below are enough for anyone who has folded a tine row.

- Wear gloves; broken positioner edges and chipped rack coating are sharp.
- Wait for the tub to cool if a cycle just finished.
- Rest the rack on a towel on the counter rather than the open door so it cannot slide off.
Tools and Parts You Need
- Small flat-blade screwdriver to pry the old positioner
- Needle-nose pliers for broken fragments
- Flashlight
- Clean towel for the rack
- Warm water to soften a stubborn old positioner
Step-by-Step Installation
- Remove the rack Roll the rack all the way out, lift the front wheels off the rails, and carry it to the counter. Set it on a towel with the tine row facing you.
- Find the positioner Fold the adjustable tine row and watch its pivot. The gray positioner sits on the rack wire right at that pivot, with its notched face pointing toward the row.
- Note the orientation Before removing anything, look at a working positioner on the same rack, or photograph the broken one. The notches face the tine row and the smooth back faces away.
- Pry off the old part Slip a small screwdriver under the edge of the positioner and lever it open, then pull it off the wire. Use pliers to pick off any fragments still gripping the wire.
- Clean the wire Wipe off scale or food film so the new positioner can close fully around the wire.
- Snap on WP8539102 Hold the new positioner with the notches toward the tine row, line it up on the wire where the old one sat, and press with your thumb until it clicks shut. It should not spin on the wire.
- Engage the tine row Lift the tine row and drop its wire into the notch for the position you want. Move it through every position to confirm each one holds.
- Refit the rack Set the rack back on the rails, roll it in and out, and load a few plates against the row to make sure it stays at the chosen angle.
Fit Checks Before You Call the Job Done
- The positioner is fully closed around the rack wire with no gap at the seam.
- The notches face the tine row and the row wire drops into them cleanly.
- The row locks in each available position and does not slip under light hand pressure.
- The positioner sits at the same spot on the wire as its neighbors on the rack.
- The rack rolls freely and the new part does not touch the tub wall.
Common Mistakes to Avoid
Installing it backwards With the notches facing away, the row simply rests on a smooth surface and falls flat as soon as you load a plate.
Snapping it onto the wrong wire The positioner must be on the fixed rack wire at the pivot, not on the moving tine row wire.
Cracking it by forcing it cold Use firm thumb pressure. If it resists, warm it in hot tap water for a minute rather than tapping it with a tool.
Ignoring rust under the old part A rusted wire will not let the positioner grip and will keep spreading. Treat or replace the rack coating first.
Troubleshooting After Installation
Tine row will not lock in any position The positioner is reversed or not fully closed. Pull it off, turn it so the notches face the row, and snap it on again.
Row locks upright but not in the middle position Check that the row wire is seated fully in the notch and that a fragment of the old positioner is not blocking it.
Positioner falls off after a few cycles The wire may be worn thinner at that spot. Compare with a neighboring positioner; if the wire is damaged, the rack itself may need attention.
Care Tips After the Repair
- Change tine row positions with the rack empty so the notches are not loaded while moving.
- Inspect rack clips and positioners every few months for chalky or cracked plastic.
- Avoid stacking heavy cookware against adjustable rows.

Frequently Asked Questions
Is WP8539102 sold as one piece or a set?
It is a single positioner. Count how many are damaged on your rack and order that many.

Yes. The 814 listed models include KitchenAid units such as KUDS02SRBL4 and KUDP02SRWH3 that share the same rack design.
Do I need to take the tine row off?
No. The positioner snaps on around the rack wire without removing the row.
Why is it gray?
