Introduction
Use this guide to replace the vent valve plunger in your LG front load washing machine.
The vent valve plunger vents moist air out the back of the washer. The plunger may stick open, which would allow excess liquid to slosh out and drip down the back of the washer.
This guide will work for most LG front load washing machines. This guide is written with a model WM3050CW washer. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.
