I have a kitchenaid model kuix305ess2 under-counter ice machine. It stopped making ice so I took the easy route and replaced the water inlet valve (part # w10897719) thinking there was not enough water or the pressure was not right. I started the machine and water flowed into the reservoir and continued until water was flowing over the top of the reservoir. I unscrewed the cap on the bottom of the reservoir to drain some water then tighten the drain cap. The reservoir filled again but then the recirculating pump started and water ran over the cooling unit. I checked later and the machine made ice. I checked the next morning and no ice. Any thoughts?
