20 Most Recent Cuisinart Grind and Brew DGB-300BK 10-Cup Coffee Maker Questions & Answers

There are (I think) three possibilities:
1. There is a fuse inside the unit.
2. The water heating element has a thermal fuse that has failed as a result of overheating (no water in the reservoir at some point)
3. The control panel has failed or the low-voltage power supply that powers the control panel has failed.

My guess would be #2. This is a readily available part (electronic supply stores) but not easy to replace (unit disassembly can be quite challenging). If you're handy, give it a try. The thermal fuse will be wired directly across the terminals of the water heating element. It will have very low resistance (~1 ohm) if it is good.

An electric coffee maker has an electric flow-through brewing water heater with a heating resistor controlled by a temperature dependent regulating switch responsive to the temperature of the heating resistor, and a warming plate heated by the heating resistor for maintaining the prepared coffee at a desired drinking temperature. Apparatus for adjustably prolonging the interruption of heating current 2 to 5 times the normal cooling time of the regulating switch is connected in circuit with the heating resistor and the regulating switch, and a manually actuated small quantity control means connects the heating current interruption prolonging apparatus in circuit with the heating resistor and the regulating switch. The prolonging apparatus may be an adjustable auxiliary electric heater in parallel with the regulating switch and thermally coupled thereto or an adjustable timer in series with the heating resistor and regulation switch and triggered by the opening of the regulating switch

I just called Cuisinart Consumer Service Center at 1-800-726-0190 and the representative I got (Christina) placed an order for the part and had it shipped to me. I didn't have to pay anything! It should be here in 7-10 days. Guess I'll be doing Starbucks until then, but a small price to pay overall for my favorite coffee maker.

The brew cycle will terminate when unit senses the temperature rise when water is gone. If scale buildup is heavy, that insulates the water from the sensor and temp will rise too soon. You should runs SEVERAL cycles of descaling as the scale has to be really built up. You might want to go heavier on the vinegar and let it set a bit before cycling. Scale is hard to breakdown... It is likely a calcium compound.

Hello stowawayray,
Cuisinart won't sell parts directly except to small appliance dealers. Hope this helps. FixYa frequently lists parts suppliers in the ads. Kind regards, NormanZ

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.

Follow the instructions in the manual for descaling. Press the 6oz and 8oz button together for two seconds. This will dispense a cup of water(since you have already cleaned) . The clean light will flash....when the cup is done the light will go out.

Mine is doing the same thing. When I unplug it and let it sit for a while, then plug it back in, it sometimes will turn back on. But then I try to use it, and it doesn’t make a single cup. A little coffee, some steam, and then it turns off again. And it’s only a yesr old. It seems to be garbage.

I recently had the problem of the dreaded "de-scale" message coming up on my coffee maker. After descaling my coffee maker 3 times, the "de-scale" message wouldn't go away. I called the Customer Service number and was told to unplug the coffee maker for an hour and that should re-set the machine. I did that and still the de-scale message remained. Another phone call and another customer service representative and I was told to hold down the Hot Water and Rinse buttons together. I placed a large mug and hit the buttons. There was a good bit of water that came through but IT WORKED! The coffee maker is as clean as can be and working very well. I suggested to the Customer Service Representative that Cuisinart should include this in the instruction and troubleshooting section. But I doubt that will happen. Sad that the web site info is not updated. Wanted to share my experience so it might help others frustrated by this issue.

Your coffeemaker features a Ready Tone that beeps 5 times when coffee is finished brewing. To turn this alert off, press Tone button; an icon will appear in display to indicate tone is off. To turn tone back on, press Tone button again; icon will disappear.
