DC31-00054D / PX3516-01 Washing Machine Drain Pump Motor Replacement

Key Features

• High-Efficiency Magnetic Core: Features a precision-wound electromagnetic copper stator designed to deliver consistent torque, enabling the pump to evacuate water rapidly during the drain and spin cycles.
• Vibration-Isolated Impeller: Equipped with a dynamically balanced, high-impact composite impeller blade assembly that maximizes water displacement while minimizing operation noise and vibration.
• Factory 2-Terminal Connection: Designed with standard 1/4-inch male spade terminals, providing a direct plug-and-play electrical connection without the need for wire cutting or splicing.
• Thermal Overload Protection: Built-in internal safety thermal fuse automatically cuts power to the motor if it becomes jammed by debris, preventing electrical shorts or fire hazards.
• Universal 3-Screw Mount: Engineered with a standard 3-hole flange pattern, allowing the motor to mount directly onto the existing plastic pump housing (volute) assembly.

Compatibility & Fitment

This replacement motor fits standard drain pump housing configurations used by major appliance brands. Key compatible series include:

• Samsung Front-Load Washers: Fits popular WF series models (e.g., WF42H5200AW, WF45H5000AW, WF42H5000AW, WF365BTBGWR).
• Samsung Top-Load Washers: Compatible with WA series high-efficiency units (e.g., WA400PJHDWR, WA45H7000AW, WA50F9A6DSW).
• Kenmore / Sears: Fits 402-prefix front-load and top-load washers manufactured by Samsung.
• Note: This product is the motor only. It does not include the large plastic filter housing body. You will reuse your existing plastic housing during installation.

When to Replace

• Washer Displaying "nd" or "5C / 5E" Error Codes: These specific fault codes indicate a drainage failure where the machine is unable to clear water within the designated time limit.
• Loud Humming or Grinding Noise: If the washer makes a loud growling sound when it tries to drain, the internal bearings or shaft of the pump motor have failed.
• Water Left in Tub: If the cycle stops before the spin phase and leaves the tub full of dirty water, the motor is likely seized or burned out.
• Intermittent Pumping: If the motor runs sometimes but cuts out when the water gets hot, the internal thermal protection is tripping due to an aged, failing motor coil.

Installation Tips

• Safety First: CRITICAL: Disconnect the washer from the wall outlet and turn off both water supply valves. Have a shallow pan and towels ready, as several gallons of trapped water may spill out when opening the lines.
• Accessing the Pump: PRO TIP: On front-load models, the pump is typically accessed by removing the front lower panel or tipping the washer back. On top-load models, lay the washer gently on its side (use cardboard to protect the finish) to access it from the bottom.
• Reuse the Seals: Clean the O-ring mating surface on the plastic housing thoroughly before installing the new motor. Lubricate the rubber seal with a drop of liquid dish soap to ensure a perfect, watertight seal.
• Check for Obstructions: Before mounting the new motor, look inside the plastic housing chamber. Use a flashlight to check for and remove foreign objects like coins, bobby pins, socks, or bra wires that may have jammed the original pump.
• Terminal Orientation: Snap the two wiring connectors securely onto the spade terminals. Because this motor operates on Alternating Current (AC), the polarity does not matter; wires can be connected to either terminal.
