I recently moved house and the Dirt Devil stood upright in a corner of my kitchen (without a pad attached) for two months. This morning, I filled it with distilled water and plugged it in, ready to clean my kitchen floor. Light was on, I could hear gurgling from the tank as the water heated, but no steam came out of the BOTTOM of the machine (pad was dry) - only a small amount where the stick handle meets the cleaning head. First time this machine has ever let me down. Unable to find specific help for this online, and currently waiting for a callback from the Dirt Devil customer service#. Can I unscrew the faceplate from the cleaning head? Could there be mineral buildup and, if so, how do I remove it? Has something corroded inside the cleaning head, and can I fix it? I hope that DD customer service is able to help ..... we'll see. Until this morning would have given this steamer an Excellent rating, but if buying a new one is the only advice I receive from DD, the overwhelming number of very negative reviews I'm seeing is cause for concern.
