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.

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.

Parts in this group on DUS500B/P1139731NB: WS26X10021 (Water Softener Valve Motor), R0905681 (Dishwasher Caster Socket), R0905669 (Ground Strap), R0901014 (NUT, 1/4-20), R0910102 (VENT, BAFFLE), R0910089 (WATER VALVE, SCREEN), W10692909 (Range Hood Recirculation Kit), WB26X28935 (Microwave High-Voltage Diode), P130600 (Furnace Blower Fan Motor), R0903520 (Connect Pump).

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.

Parts in this group on DUS500B/P1139731NB: R0910077 (Spray Arm Assembly), R0903548 (Spray Arm Tube), R0905672 (Sump Cover).

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 DUS500B/P1139731NB: WB03T10233 (Range Surface Burner Knob), R0905624 (DETERGENT TRIP SPRING).

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.

Parts in this group on DUS500B/P1139731NB: 5304482406 (Dishwasher Water Inlet Valve).

Before you buy

Match DUS500BP1139731NB 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.
