Common failure areas on this model
The confirmed parts above group into a handful of failure areas. Here is what each points to and how to check it before you order anything.
Storage, trim and cosmetic hardware
Symptom: A cracked shelf, broken door bin, worn hinge, or missing trim piece -- cosmetic and storage wear rather than a functional breakdown.
Check: Match the physical dimensions and mounting tabs of the old part before ordering; these pieces are often model-specific even between visually similar models.
Parts in this group on DWU4912AAE: WPY912709 (Adjustable Peg Clip), WP99001443 (Spray Diverter Cap), 912546 (Rack Stop).
Filtration and spray system
Symptom: Dishes come out with food residue, spots, or a cloudy film, or you notice leftover debris in the tub bottom after a cycle.
Check: Remove and rinse the filter assembly under the tub, and check that the spray arm spins freely and its jets aren't clogged -- these are the first things to check before assuming a pump has failed.

General hardware and mounting parts
Symptom: A small mechanical or mounting part has failed, cracked, or gone missing.
Check: Compare the physical shape and mounting points to the original piece, and confirm the exact part number against your model plate before ordering.

Dishrack hardware (rollers, wheels and tines)
Symptom: A dish rack that binds, drags, or comes off its rail track when you pull it in or out, or a rack with a cracked, loose, or missing wheel or tine.
Check: Pull the rack fully out and check each wheel or roller for a crack or a missing axle pin, and check that tines aren't snapped off or pushed out of alignment along the row.
Parts in this group on DWU4912AAE: WP99002138 (Rear Bowl Tine).
Controls, timers and wiring
Symptom: A cycle that stops partway through, an error code or blinking light, or the unit not starting at all.
Check: Look for burn marks or a burnt smell near the board or terminals, and check whether buttons and knobs respond -- a unit that powers on but won't cycle often traces back to this group.
Parts in this group on DWU4912AAE: 99001004 (Float).
Water inlet and drainage
Symptom: The dishwasher won't fill, or dishes come out with standing water still in the tub bottom after the cycle ends.
Check: Check the inlet valve's screen filter for sediment, and check the drain pump and drain hose for a clog or a jammed object -- a piece of broken glass or a bottle cap is a common culprit.

Before you buy
Match DWU4912AAE exactly against the model and serial plate on the appliance itself before ordering anything — a single mismatched character can point to a different production run with different parts. Then check the part number printed or stamped on the part you are replacing against the part numbers in the table above; the printed number is the most reliable way to confirm fitment when a model has gone through multiple production runs. RepairKitHub does not sell parts directly — every part link above routes to an Amazon search for that part number so you can compare current listings and sellers yourself.
How to confirm this is your model
On most dishwashers, the model and serial plate sits on the edge of the door or the tub rim. Match every character exactly, including letters and dashes at the end — appliance model numbers often have similar prefixes but different suffixes for different production runs.
