After reading all the reviews, I decided to purchase the DCM18s Brew n Go coffee maker. I followed the instructions on how to use from the start.Had a difficult time pouring the water into the reservoir because of how the door is placed on the unit. The first step to to purge the unit and run just clean water into the unit.That worked and I did a second purging. That's when I notice the unit ran longer than the first run. Finally the unit shut off. I unplugged the unit to make sure everything was okay.I plugged the unit back in and it will not operate. I thought it may have a safety fuse or some kind of overheat prevention that caused the unit to shut down. I read the manual instruction and waited for the unit to rest. No luck. It simply will not turn on after many attempts. So, this unit is going back to amazon.com for a refund.
