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 CLSUP-6: 51503 (Snapper Drive Disc), 51452 (KIT-START RELAY (INCLS. CODE 25)), 51301 (Hfhs M8 X 1.), 51425 (Frame Assembly), 51127 (JVC S/m Av2775), 51575 (FRAME ASSEMBLY (L.H.)(USED ON CL SUP-7, CL3000-5, CL3300-1, CL3500)), 51049 (SEAL-AIR INLET), 51300 (O-ring 0.103), 51445 (Snapper Chute Brake).

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 CLSUP-6: 51548 (SIDE PANEL KIT (WHITE) (L.H.)), 51457 (Hex Screw Fa), 51138 (Axle Bracket), 51136 (Bypass Spring), 51325 (Control Panel), 51304 (Grommet).

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 CLSUP-6: 51440 (Cup Gasket).

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 CLSUP-6: 51231 (Pulley), WP4162322 (Dishwasher Single Roller Wheel).

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 CLSUP-6: CLS30320001 (Genuine Kenmore Refrigerator Water Filter 9990 CLS30320001).

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 CLSUP-6: 318946500 (Range Oven Light Bulb).

Before you buy

Match CLSUP6 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.
