Key Features

• Precision-Ground Stainless Steel: Manufactured from high-carbon, corrosion-resistant stainless steel designed to maintain a razor-sharp edge through thousands of wash cycles, effectively pulverizing food debris.
• Self-Cleaning Macerator System: Engineered as a critical part of the dishwasher's internal filtration, this blade grinds down soft food particles so they can pass safely through the drain pump without causing clogs.
• High-Torque Drive Interface: Features a reinforced central hub designed to lock securely onto the circulation pump's motor shaft, ensuring consistent rotation and vibration-free performance.

Compatibility & Fitment

This chopper blade is the standard internal grinding component for many Whirlpool-manufactured dishwashers produced between 1998 and 2015. Key compatible brands include:

• KitchenAid: Fits many KUDI, KUDL, KUDM, and KUDC series units featuring the "PowerClean" soil disposer.
• Whirlpool & Maytag: Compatible with hundreds of GU, DU, and MDB series models (e.g., GU2400XTPB, MDB7601AWB).
• Kenmore (665 Series): Fits many 665-prefix "Ultra Wash" dishwashers produced for Sears (e.g., 665.1573291, 665.16362).
• Jenn-Air & Estate: Direct fit for high-end JDT series and budget-friendly DU units utilizing the 8268383 blade style.
• Note: This part is located inside the Sump Assembly, beneath the lower spray arm and screen filter. It is not compatible with newer "filter-only" models built after 2016.

When to Replace

• Loud Grinding or Rattling: A loud mechanical noise during the wash cycle, often indicating the blade has snapped or is loose and hitting the internal screen.
• Clogged Drain Pump: If the blade is dull or broken, food particles aren't ground down, leading to persistent clogs in the drain hose or pump impeller.
• Poor Cleaning Results: Debris is being recirculated and sprayed back onto the dishes because the chopper is not effectively clearing the sump filter.
• Visible Blade Damage: Upon inspection, the stainless steel blades look bent, chipped, or are completely missing from the center hub.
• "F9 E1" or "Long Drain" Errors: While often a pump issue, a failed chopper can lead to massive debris buildup that prevents the dishwasher from draining within the allotted time.

Installation Tips

• Safety First: You MUST unplug the dishwasher or turn off the circuit breaker. This repair requires accessing the sharp internal components of the pump motor.
• Access the Sump: Remove the lower dish rack and the lower spray arm. You will need to remove the screws holding the filter screen to reach the chopper blade housing at the bottom of the tub.
• Inspect the Screen: While replacing the blade, check your 8268383 Chopper Screen for holes or wear. If the screen is damaged, the new blade will not be able to macerate food properly.
• Verify Drive Shaft Alignment: Ensure the new W10083957V blade is pushed all the way down onto the motor shaft until it seats. If it is loose, it will spin off during the first cycle.
• The "Spin Test": Once installed, spin the blade manually with your finger to ensure it clears the surrounding housing and screen without rubbing or catching.
