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.

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 66515951794: 8274221 (Inlet Valve).

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 66515951794: WP3378144 (Dishwasher Middle Wash Arm Tube), 3378147 (Dishwasher Spray Arm).

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 66515951794: 3380781 (Silverware Basket), 9742994 (Mount).

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 66515951794: 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 66515951794: 717273 (Dishwasher Heating Element Rubber Washer), 661566 (Dishwasher Thermostat).

Before you buy

Match 66515951794 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.
