I replaced the water inlet valve and the new hose supplied in the kit. Very simple to replace the valve. Threading the new hose was also pretty simple. The ice machine works like new and it's about half as loud with the new parts. Since I had it all apart, I went ahead and added a filter which the builder should have done. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
