Maytag MDB8989SHK0 wash-system chopper W10591562 is separate from drain pump
W11337779 Rev. A is a Maytag parts list for the exact model MDB8989SHK0 (Cast Iron Black). Printed p. 12 places chopper assembly W10591562 at its own position and pump, drain W10348269 at another. It also lists accumulator, sump, motor, drain hose, lower spray arm, diverter, and seals as distinct parts. That separation helps identify a grinder/chopper-related part without claiming a drain problem is its failure.
Safety boundary
- The chopper and pump are internal powered/water-bearing components. Keep hands out of the sump and have a technician diagnose or replace them; the part list is identification evidence, not a repair procedure.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.
Required identifiers
- Exact model: MDB8989SHK0 (Cast Iron Black)
- W11337779 Rev. A printed p. 12: chopper assembly W10591562
- Drain pump W10348269 is a separate part on that page
- The parts list is for this one E-Nr-like model code, not an MDB8989 family inference
Compatibility rules
- The Maytag repair-parts list cover names only MDB8989SHK0 Cast Iron Black.
- Its pump/motor table distinguishes chopper W10591562 from drain pump W10348269.
- The same figure assigns separate numbers to accumulator, motor, sump, and drain hose.
- No current stock, supersession, or fault diagnosis is inferred from the historical part list.
Never assume
- W10591562 is the drain pump.
- A drain symptom by itself identifies a failed chopper.
- The chopper is a routine removable filter for the owner.

Do not swap part functions
Accumulator W10591545 and the motor/sump assembly are separate positions. A no-drain symptom is not enough to select a chopper or pump.
