I went out on a service call and the complaint was water constanting dripping into the tub at all times, even when the washer was not being used. Over time the water inlet valve wears out and causes this to happen.

I replaced the water inlet valve and it worked great! No more dripping water into the tub.

Here’s the water inlet valve for this model:
WP22002360 Water Inlet Valve

There is a video in the water inlet valve part link that shows you how to replace it.
