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 WSSUP-2: 51621 (Insulation), 51647 (BIMETAL ASSEMBLY (BLK) (USED ON WS400-2, 3 AND WS850-2, 3)), 51512 (BLOWER ASSEMBLY KIT (INCL. CODES 9 THRU 16)), 51601 (IMPELLER AND SEAL KIT (INCL. CODES 5-8)), 51125 (Control Arm), 51121 (Control Arm), 51627 (Retainer Ring), 51129 (10tx 48t Gea), 51523 (Lawn & Garden Equipment Slotted Washer), 51285 (Casing Back), 51272 (Bowflex Leg Cable), 51230 (Fan 7), 51219 (Snapper Drive Disc A).
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 WSSUP-2: 51606 (BRACKET, OVAL THERMOSTAT).
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 WSSUP-2: 51534 (CLIP-ARM GUARD (4) (FRONT AND REAR LOCATIONS)), 51530 (SUPPORT-BLOWER).
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 WSSUP-2: 51207 (ROLLER-UPPER RACK (4)), 51198 (Pulley).
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.

Before you buy
Match WSSUP2 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.
