W10872845 / 8579307 Dishwasher Pump Filter Cup Replacement

Key Features

• Precision-Slotted Filtration: Engineered with a specialized slotted surface designed to capture medium-to-large food debris (like seeds, bones, and glass shards) before they can enter the circulation or drain pump, protecting the internal impellers.
• High-Impact Structural Polymer: Manufactured from a reinforced, heat-stabilized plastic that resists warping and degradation even through thousands of "Sani-Rinse" and "Heated Dry" cycles.
• Vortex Flow Dynamics: Features an optimized internal geometry that maintains consistent water flow to the wash motor, ensuring full spray arm pressure for a 360-degree clean while keeping debris safely trapped.
• Snap-Lock Seat Interface: Designed with a standardized "twist-to-lock" mounting system that provides a secure, vibration-resistant fit at the bottom of the dishwasher sump.

Compatibility & Fitment

This filter cup is the primary debris trap for many Whirlpool-manufactured dishwashers produced over the last 15 years. Key compatible brands include:

• Whirlpool & Maytag: Fits hundreds of WDT, WDF, and MDB series models (e.g., WDT720PADM, MDB4949SHZ).
• Kenmore (665 Series): Compatible with various 665-prefix "Elite" and standard dishwashers (e.g., 665.13263K311, 665.13282K113).
• KitchenAid & Jenn-Air: Fits dozens of KDTM, KDTE, and JDT series high-end units utilizing the W10872845 style.
• Amana, Roper, & Estate: Direct fit for ADB and DU series units produced by Whirlpool.
• Note: This filter cup is typically located at the Bottom Center of the Tub, often nested within the main screen filter.

When to Replace

• Standing Water in Tub: A heavily clogged or scaled-over filter cup can prevent water from reaching the drain pump, leading to "Long Drain" or "F9 E1" errors.
• Visible Cracks or Holes: Any physical damage to the plastic housing allows damaging debris (like cherry pits or glass) to bypass the filter and potentially snap the pump impeller.
• Gritty Residue on Dishes: If the filter is not seated properly or is damaged, food particles will recirculate and settle back onto your clean glassware.
• Loud Grinding Noise: Often follows a failed filter; if the cup is missing or broken, debris enters the pump, causing a loud mechanical rattle during the wash or drain phase.
• Persistent Dishwasher Odors: A filter cup that is saturated with old grease and calcium buildup can harbor bacteria, leading to a "swampy" smell inside the dishwasher.

Installation Tips

• No Tools Required: This is a simple "twist-out, twist-in" replacement. Open the dishwasher door and remove the lower dish rack for full access to the tub floor.
• The "Quarter-Turn" Method: Most filter cups are removed by twisting counter-clockwise. Pull the old cup out and inspect the sump area for any debris that might have snuck past.
• Clean the Surrounding Screen: While the cup is out, it is the ideal time to rinse your **W10463906 Main Screen Filter**. Use a soft brush and warm soapy water to clear any mineral scale.
• Verify the Seat: Insert the new W10872845 cup and twist clockwise until you feel it "click" into place. If it is loose, it will vibrate and allow debris to leak through.
• Monthly Maintenance: To maximize the life of your pumps, remove and rinse this cup once a month to prevent grease and silt buildup from restricting water flow.
