Won't Power On?
Check to see if it is plugged in; if it is, unplug the machine, plug it back in, and press the ON/OFF power button again. If the machine still does not operate, check the fuse or circuit breaker on the electrical circuit it is connected to and make certain the circuit is closed.
Does water need to be added?
Make sure the water tank is fully seated on the brewer. Press down on the tank to ensure it is firmly in place.
