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 WS850-2: 51673 (Fount Bail), 51580 (TANK AND FRAME ASSEMBLY (WS850, 1 AND 2) (NOT SHOWN)), 51544 (Casing Front), 51317 (Shut Off Rod), 51146 (Hydro-Gear Hfhcs 1/4-20), 51120 (Lt Door Assy), 51274 (WASHER (2)).
Storage, trim and cosmetic hardware

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.

Before you buy
Match WS8502 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.
