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 KUDB23HB0: 675705 (Impeller), 3369482 (Check Valve), 4171555 (Bumper), 303539 (Impeller), 302718 (Dishwasher Chopper), 675703 (Pump Seal Kit), W10779716 (Bake Element), WP302711 (Dishwasher Pump Outlet Seal), 675238 (Drain Check Valve with O-Ring), 370445 (Clamp), 72107 (Touchup Al), 350930 (Spray Paint - 12 oz. - White), 72017 (Touch-Up Paint - White).

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 KUDB23HB0: 00749228 (Relay Control Board).

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 KUDB23HB0: 4171221 (Rinse Aid Cap), 4159184 (Screw), 00631273 (Control Knob), 3367670 (Screw).

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.

Before you buy

Match KUDB23HB0 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.
