My GE washing machine was very slow to fill and had a slow drip when the water was off which was leading to a water buildup inside the drum. Replacing the valve solved the problem completely and the washer fills quickly and doesn't drip.

Installation is pretty simple. There are rubber hoses that connect onto intakes on the valve, held on with metal clamps. The clamps were fairly difficult to open up and I assume they're the same or similar on every GE washer that uses this valve.  I'd recommend using a set of wide pliers that can hold the spring open while you get a friend to help pull the hoses on and off.

Overall replacing this valve is a really easy job and may save you the cost of a repair man.
