I bought gt300 coffee maker (display unit) with no instruction booklet.

See page 10 of your user's manual; if you misplaced it, go to:
Cuisinart DGB 900BC Instruction Booklet Page 10

If the instructions listed half-way down the page don't help, contact Cuisinart customer support, or return the coffee maker to the store you bought it from.

The Instruction Booklet for the Cuisinart DCC-2600 Brew Central 14-Cup Programmable Coffeemaker is available here:

http://www.cuisinart.ca/pdf/ibs/en/DCC-2600C_en.pdf

See page 9 of the booklet for Cleaning and Maintenace and use of the clean button.

Upon visual inspection of the PC board, a small portion of the board had been burned. Using a voltmeter to check components in that area, it was discovered a 24 volt zener diode was nonfunctional. I then purchased two 12 volt zener diodes (no 24 volt was available), and installed / soldered them, in series, on the PC board. I then reassembled the Gevalia cm 500 unit and made delicious coffee. What remains unknown is what precipitated the failure of the 24 volt zener diode.

You have to use the "Auto-Off" feature, which is located on the same button as on/off:
The automatic shutoff time (ASO) can be
programmed to shut off immediately after
brewing (0:00) or up to 4 hours later. The
default shutoff time is 2 hours.
Press and hold the On/Off button to display
current shutoff time. To change the preset
time, press and hold the On/Off button until
the red power light and LCD display begin to
flash. This signals that you have entered the
Set automatic shutoff mode. Set the time
you want coffee to begin brewing by
following the instructions in “Entering Time
Set Mode.”
When the coffeemaker shuts itself off, two
tones will sound.
NOTE: Automatic shutoff may be
programmed either before or during coffee
brewing. If you program the auto shutoff
time after brewing is completed the unit
will automatically account for elapsed time.
For example, if you set the auto shutoff for
40 minutes and 25 minutes have already
elapsed, the unit will shut off automatically
after 15 minutes (40 minutes minus the 25
elapsed equals 15 minutes).

Sounds like the sswitch is bad.

yea, go to www.braun.com, choose United States and then go to choose appliance, and then choose coffee makers. Yours is listed there on the left hand side. I can download it and send it to you if you wish.
Thanks!

Try holding down the top while sliding the lever towards you. Without holding down the top, I've had the same problem.

I fixed mine! The idea here is to help fill the tube inside back up with water. The unit may need a little help to get the suction going.

Preparation: Set the unit so you can easliy reach the back side of the unit. Fill the container with 7 - 14 oz of water and have it nearby. Place a cup underneath the coffee drip container in the front. Have another small cup of water handy.

Process: Plug in the unit to an outlet. Hold as much water in your mouth as you can. Press the CLEAN button on the unit then put your lips over the water inlet valve on the back of the unit. Force (blow) the water from your mouth into the inlet valve. You should begin to hear the unit pushing the water through. Place the water container over the water inlet valve after you have released the water from your mouth. The unit should continue to empty the water container. Now, you just have to fill the water container and make a cup of coffee.

This is the same procedure I performed to get mine going again; I am not trying to make you look like an idiot.
