When water is supplied from the water supply valve of the washing machine, the valve operates and creates “woong~” operating noises.
When water is supplied, the valve is closed, creating a “tak” noise.
If the water supply filter is clogged and water passes through a narrow space or the water pressure is high, a “gurgling” noise may be created. Also, during final rinsing, water is supplied to the fabric softener dispenser which has a smaller area than the detergent dispenser, so the sound of water supply may be different from the normal water supply sound.
A “woong~” noise heard from the water supply valve of the washing machine during water supply is a natural sound of valve operation.
It is created in the process when the water supply valve is opened by electricity and water is supplied.

The sound of water is different during rinsing.
During final rinsing, water is supplied to the fabric softener dispenser in order to add fabric softener to the tub.
At this time, water is supplied to the fabric softener dispenser which has a smaller area than the detergent dispenser, so the sound of water created may be different from the normal sound of water being supplied.This guide was created for all models, so the images or content may be different from your product.
