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.

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 RUD1000DB2: 3369038 (Dishwasher Grommet Washer), 3368922 (Torx Screw), WP3369031 (Dishwasher Drain Cover Seal), WP3371745 (Dishwasher Support & Bearing Assembly (In), WP3369011 (Dishwasher Pump Housing Kit), 3376404 (Cover Dispenser), 3372028 (Dishwasher Detergent Dispenser Cover Hinge Pin), WP3369769 (Dishwasher Door Panel Insert), 4318050 (Door Spring & Clip Kit), WP3378138 (Dishwasher Soap Dispenser Cover), WP8066018 (Dishwasher Detergent Lid Spring), 3368921 (Range Screw).

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 RUD1000DB2: 3378779 (Inlet Valve), W10844024 (Water Inlet Valve), WP3374077 (Dishwasher Drain Hose w/Connector Ends).

Door, lid switches and latches

Symptom: The dishwasher won't start, or stops mid-cycle, unless the door is fully latched shut.

Check: Listen for an audible click when the door latches. No click, or a visibly worn or broken latch or strike, points to this part.

Parts in this group on RUD1000DB2: 3368953 (Door Latch), 4318273 (Dishwasher Door Switch), WP3368955 (Dishwasher Door Switch Plunger), WP3380854 (Dishwasher Door Latch Bolt), WP3372028 (Dishwasher Lid Hinge Pin).

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 RUD1000DB2: 8193646 (Lower Detergent Dispenser Actuator Assembly).

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 RUD1000DB2: W10161215 (Lower Dishrack Kit), WP3376961 (Dishwasher Lower Dishrack Wheel), 675679 (Tine Tips), 676458 (Dishwasher Tine Tip Set, 125-pack (Gray)), W11169039 (Dishrack), WP676455 (Dishwasher Dishrack Vinyl Touch-Up Paint, 4-oz (Gray)).

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 RUD1000DB2: 3376927 (Dishwasher Door Seal).

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 RUD1000DB2: 717273 (Dishwasher Heating Element Rubber Washer).

Before you buy

Match RUD1000DB2 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.
