Customer Questions and Answers for Dishwasher Circulation Pump Motor (Dc) by Lg

This DC motor assembly drives the dishwasher's circulation pump, moving wash water through the spray arms for consistent cleaning. Replacing a weak or failed motor restores proper water movement and wash pressure when cycles run but dishes stay dirty.

• Powers the circulation pump to move water through spray arms during wash and rinse
• Failure may cause poor cleaning, no spray action, or a silent/stalled wash cycle
• Humming, grinding, or buzzing from the pump area can indicate a failing motor
• May lead to unusually long or incomplete cycles due to low circulation

• Disconnect electrical power and shut off the water supply before servicing
• Access from the bottom; remove the toe panel and tilt/lay the unit back to reach the pump/motor
• Mark and unplug wiring, release clamps/fasteners, and install the new motor with seals aligned as originally positioned
• After reassembly, run a short cycle and check for leaks and proper spray action
