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.

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.

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 DU8750XB1: 3373623 (Wire Harness), 3373367 (Cover Timer), 3369611 (Timer Knob), 8271507 (Dishwasher Motor Wire Harness).

Interior lighting

Symptom: The interior light doesn't turn on when the door opens.

Check: Confirm power is reaching the socket, then check the door-activated light switch before assuming the bulb itself is at fault.

Parts in this group on DU8750XB1: 3369318 (Indicator Light).

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 DU8750XB1: 3368300 (Spray Arm), 3368290 (Dishwasher Upper Spray Arm Support).

Heat control (thermostats, fuses, heating element)

Symptom: Dishes don't dry at the end of the cycle, or a heated-dry setting doesn't seem to do anything.

Check: With the dishwasher unplugged, check continuity across the heating element or thermostat with a multimeter -- no continuity means it has failed.

Parts in this group on DU8750XB1: 3370555 (Thermostat Bracket), 3373359 (Dishwasher Thermostat).

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 DU8750XB1: 300845 (Dishwasher Dishrack Slide Rail Stop, Upper).

Before you buy

Match DU8750XB1 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.
