Mine does this all the time. When it does, I tap the top of the machine and the coffee comes out. I don't know if it will work for you, but it works every time for me. It's like there's a small clog or something.

There are 4 steps to fix this:

1. Simultaneously press and release "small mug" and "medium mug". Immediately afterward press "menu" 3 times. (Menu is the black button under the display screen.) You should see a time 6:09 on your screen.

2. Press "menu" once. Your LCD screen should say Brew 0:00.

3. (I messed this step up like 10 times and had to unplug the machine, then replug it and start over at step one. You have to unplug if the LCD displays "auto ____". If it continues to flash "Not Ready" and "Brew" then you can just keep trying step 3). Press and hold "medium mug". While holding "medium mug" press and release "menu". Immediately after pressing "menu" (while still holding "medium mug") press "small mug". Release "small mug" and "medium mug" at the same time. This entire thing needs to be done very quickly. as soon as you release "menu" go to "small mug" and release both buttons quickly.

4. Unplug the machine (do not turn it off). Wait for 3 seconds or so. Plug it back in, turn it on and follow the instructions for priming.

The Automatic Shutoff Time can be programmed
anywhere from immediate shutoff
after completion of the brew cycle up to four
hours. When the coffeemaker shuts itself off,
two tones will sound. Four hours is the default
time. The 0:00 setting shuts the unit off immediately
after brewing is complete. To check the
current setting, press the “On/Off” button and
the Automatic Shutoff Time will be displayed.
To change the preset time, press and hold the
“On/Off” button until the red “power” light
begins to flash. This signals that you have
entered the “Set Automatic Shutoff” mode.
Press the “Hours” and “Minutes” buttons
to scroll forward through the digits until
desired time appears. The first setting which
appears is preset at “4:00” and the next
display will be “0:00”, since four hours is the
maximum Automatic Shutoff setting. Pressing
and holding either button will allow you to
scroll continuously, slowly at first, and then to
accelerate to the rate of about three digits per
second. As the desired time setting approaches,
release the button and then press repeatedly
to advance one digit at a time.
The Automatic Shutoff Time (ASO) may be
programmed either before or during coffee
brewing. You may also re-program the ASO
time when brewing has been completed. If you
do so, the Automatic Grind & Brew™ will automatically
account for any time that has already
elapsed after brewing.

You are not doing anything wrong.. that's the way this uint works.
