I have a GE Profile Water Cooler. We replaced the bottle of water on Wednesday morning and noticed that the bottle was cracked and leaking down the side. We removed that bottle and put another new one on the water cooler. Everything looked fine. We were gone from Wednesday at noon until Friday morning. We found the water cooler in a big puddle and the new bottle was empty. I unplugged the unit and removed the remaining water. I dried everything and found water inside the bottom of the cabinet. I removed the top and back expecting to replace a little hose or tighten a clamp. I didn't find any obvious leaks. I removed the foam insulation around the reservoir and found a ring of ice that was slowly melting. I removed the ice and dried everything. I put water in the reservoir but didn't find any leaks. Do you have any ideas?

I have same problem and did the same things as you did. Did you ever figure it out?
