LG Dishwasher Motor Parts

LG Dishwasher Motor Parts

The circulation pump motor and drain pump motor are the two motors that keep an LG dishwasher running. When either one fails, you'll notice poor cleaning action, standing water after the cycle, or the dishwasher won't start at all. OEM LG motor assemblies are engineered to match your model's flow rate and pressure — aftermarket substitutes often cause leaks or weak performance.

Repair Clinic carries genuine LG dishwasher motors for every current and legacy model. Enter your model number to find the exact circulation pump motor, drain pump motor, or motor assembly your dishwasher needs. Same-day shipping available on in-stock motors.

• Circulation pump motor: No wash action, dishes stay dirty, weak spray from arms
• Drain pump motor: Standing water in tub after cycle completes
• Motor assembly: Complete motor with housing, seal, and impeller
• Motor coupling: Connects motor to pump; worn or cracked couplings cause slippage
• Motor capacitor: Motor won't start or runs sluggishly; capacitor failure is more common than motor failure

LG Dishwasher Motor Questions & Answers

What's the difference between circulation pump motor and drain pump motor?

The circulation pump motor pressurizes water and drives it through the spray arms during the wash cycle — no circulation means no cleaning. The drain pump motor empties the tub at the end of the cycle. Both are critical. If only standing water is the problem, the drain pump is your focus; if dishes aren't getting clean, the circulation pump is the likely culprit.

How do I know if my LG dishwasher motor has failed versus the capacitor?

The motor capacitor fails more often than the motor itself. If the motor won't start but you hear a hum or buzzing from the pump area, the capacitor is usually the problem — it's a $20 to $40 part. If there's no sound at all, the motor may have seized. Always test or replace the capacitor first before condemning the motor.

Why does my new LG motor keep leaking?

Aftermarket motors often use different seal designs than OEM LG motors. The pressure and flow rates differ, causing seals to fail within weeks. OEM LG motor assemblies include the correct pump housing, seal kit, and impeller as a matched set — that's the repair that lasts.

Can I use a universal dishwasher motor in my LG?

No. LG dishwashers have specific motor mounting flanges, inlet/outlet port sizes, and voltage/Hz ratings. A universal motor will not fit the mounting bracket or connect to the pump assembly correctly. Always use the model-specific OEM LG motor.

LG Dishwasher Model Number: Where to Look

On LG dishwashers, look for the model number along the inside edge of the door or on the tub rim. Open the door fully and check the sides and top edge for a label listing the model and serial numbers. You may need a flashlight to read the tag, but no disassembly is required. Type the model number into the search bar to filter the full catalog to parts made for your specific dishwasher, including motors and every other associated part. Using the complete model number removes confusion between similar LG units and helps you order with confidence knowing the fit is right.
