Query: DO NOT BUY THIS MACHINE!!!!!

We bought this machine in December and it worked great until this week. I read the website and it lead me to believe the needle was clogged. After descaling it, the machine now only produces half a cup. Read all the online reviews. The water pump seems to have issues. I am frustrated because we have become addicted to great coffee!
