The telephone support was very poor! The person was either unable or unwilling to answer my question regarding the replacement of the water filter. She kept telling me there were three parts to the assembly. I only saw two, the long clear plastic unit and an oblong filter. Nothing clicked into place as she described. The person kept telling me to go to the website to learn how, and I told her I had and I didn't find any tutorial about replacing the water filter. The person kept telling me most people don't use the water filter. That answer was not what I was hoping for.
