Overview

The LG 3W20018B Washing Machine Leg Adjustment Wrench is a genuine OEM spanner tool designed to simplify the process of leveling compatible LG washing machines. Washing machines that are not properly leveled can vibrate excessively, walk across the floor during spin cycles, and produce unnecessary noise. This wrench is specifically shaped to grip the adjustable leveling feet found on a wide range of LG washer models, allowing you to turn them with confidence and precision without the slipping or rounding that can occur with general-purpose tools.

As a genuine LG Electronics part, the 3W20018B is manufactured to the same standards as the components that shipped with your machine. It is a small, durable tool that requires no power or special skills to use — simply fit it over the leveling leg and turn to raise or lower that corner of the machine until it sits evenly on the floor. Whether you are installing a new washer, re-leveling after a move, or correcting a machine that has shifted over time, this wrench provides the right fit for the job. Be sure to verify your washing machine's model number against LG's compatibility list before purchasing.
