LG Dishwasher Parts Assembly (Part # AGM30016301)

Restore high-pressure spray action, whisper-quiet operation, and dependable wash performance to your kitchen with this Genuine OEM LG Dishwasher Circulation Motor & Sump Pump Assembly. This factory-certified, heavy-duty motor module serves as the primary engine driving water circulation throughout your appliance, ensuring continuous, dynamic water flow during wash cycles.

Mounted directly to the underside of the main tub basin, this integrated assembly features a high-efficiency BLDC (Brushless DC) drive motor, precision impeller housing, pre-attached molded rubber elbows, and factory hose clamps. When signaled by the main electronic control board, it draws filtered water from the bottom sump and forces it upward at high velocity through the lower, middle, and upper spray arms to break down stubborn food soil.

If this part fails, the internal motor windings can burn out, bearings can wear down causing loud noises, or the internal impeller blades can lock up from trapped debris. This leads to common failure symptoms, including dishes remaining dirty after a complete wash cycle, spray arms failing to spin, a loud buzzing, whining, or grinding sound from under the tub, or mid-cycle operation halts paired with error codes (such as “LE” for motor lock error or “E1” wash system faults).

Quick Info

• Compatibility: Precision-engineered for select LG and Kenmore/Kenmore Elite built-in dishwashers.

• Advanced Features: Integrated variable-speed BLDC motor, pre-fitted heavy-duty black rubber coupling hose with tension clamp, grounded mounting bracket, and multi-pin factory wire harness connector.

• Fixes Common Issues: Resolves “LE” motor error codes; lack of water spray pressure; dishes coming out dirty; loud humming, grinding, or buzzing during wash cycles; and unpowered circulation pumps.

• Difficulty: Intermediate to Advanced. A manageable DIY repair requiring basic hand tools (nut driver, pliers, screwdriver), pulling the dishwasher slightly out from under the counter, and roughly 45 to 60 minutes.

💡 Critical Diagnosis & Prevention Tip

If your dishwasher displays an “LE” (Locked Rotor/Motor Error) code, the circulation pump motor is either electronically seized or mechanically jammed by foreign objects.

Before replacing the assembly, check if your unit drains properly. If the tub empties fine but the wash cycle immediately triggers an “LE” code when it tries to spray, the main wash motor (AGM30016301) is the culprit. When installing your new motor assembly, ensure the rubber elbow coupler is aligned completely flush and the spring clamp is seated tightly over the ridge to prevent high-pressure water blowouts under the cabinet!

Step-by-Step Replacement Guidelines

1. Safety & Power Isolation: Shut off the dedicated electrical breaker for the dishwasher at your home’s main service panel, and turn off the manual hot water supply valve located under the kitchen sink.

2. Uninstall and Access Under-Tub: Remove the bottom kickplate screws. Disconnect the water supply line and drain hose under the sink, unbolt the top mounting brackets from the countertop, and carefully slide the dishwasher forward a few feet to expose the bottom cabinet.

3. Position the Unit: Gently tilt or lay the dishwasher on its back (placing a towel underneath to catch residual sump water) to gain clear, direct access to the lower base pan and motor housing.

4. Remove the Failed Motor Assembly: Unplug the main wiring harness plug and ground wire attachment from the motor. Use pliers to compress and slide back the tension hose clamps on the rubber coupler hoses, unbolt the mounting bracket screws, and pull the old motor assembly free.

5. Install the New Assembly: Position the fresh OEM assembly into the sump port, slide the rubber hose connections fully onto the nozzles, and secure the tension clamps tightly over the mounting points. Reattach the electrical harness and ground wire, bolt the bracket in place, upright the appliance, reconnect utility lines, and run a test cycle to confirm zero leaks and smooth operation.
