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.

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 KUDC230B0: 4161592 (Dishwasher Door Hinge Support Bracket), WP9741257 (Screw), WP9741366 (Tube), WP1163839 (Room Air Conditioner Screw), 4160480 (Adjustable Arm Retaining Clip), WP9741251 (Mounting Bracket), 9741052 (Screw), WP3371152 (Screw & Seal 10-32 x 3/4), 4171221 (Rinse Aid Cap), 4159184 (Screw), 00631273 (Control Knob), 3367670 (Screw), 343641 (Screw).

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 KUDC230B0: WP9741853 (Dishwasher Timer Knob (Black)), WP9743413 (Dishwasher Float Switch), 00749228 (Relay Control Board), W10207863 (Float Stem Kit), 9743070 (Dishwasher Float Dome).

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 KUDC230B0: 4171566 (Upper Spray Arm Receiver), WP4171544 (Dishwasher Upper Spray Arm Manifold).

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 KUDC230B0: WP4162321 (Dishwasher Dishrack Roller Stud), 676458 (Dishwasher Tine Tip Set, 125-pack (Gray)).

Drive system (belts, pulleys, motors)

Symptom: A dish rack, spray arm, or wash-motor component isn't turning or sliding the way it should.

Check: Check that the part in question turns or slides freely by hand, and look for a cracked, worn, or seized point where it should pivot or roll.

Parts in this group on KUDC230B0: WP4162322 (Dishwasher Single Roller Wheel).

Door and drum seals

Symptom: Water leaking out from around the door during or after a cycle.

Check: Check the door gasket for tears, flattening, or a section pulled loose from its channel, and confirm it seats evenly all the way around when the door is closed.

Parts in this group on KUDC230B0: WP9740674 (Dishwasher Drain Cover Gasket), 717000 (Dishwasher Circulation Pump Gasket).

Before you buy

Match KUDC230B0 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.
