Cuisinart grind and brew 10 cup grinder stopped working

It worked yesterday. I did grind the coffee a couple of times because the grinder hasn't been working right lately. You can hear it working but the coffee wouldn't move to the filter. Grinder will not turn on now at all.

    The grinder is not reliable and has been getting progressively worse.

    More often than not, in auto or manual, the grinder does not start.

    I've started grinding the beans manually and putting them in the basket.

    Wondering if there is a relay that can be replaced. (or maybe a controller board.)

    I had a similar problem with my cuisinart grinder and I solved it by removing the circuit board and sensors completely. The machine comes apart very easily by twisting the hopper counter clockwise until it unscrews from the base. The are 4 screws at the bottom underneath the rubber cushions, one underneath the top and to the front. There are four more screws holding on the top. After removing all these everything will come apart to reveal the wires. Notice that a red and a black wire come from the electric motor (you will need to remove some of the wire covering on the ends for the new connection). Those are the ones you will be working with. So cut the leads coming unto the machine (just at the very ends where they connect-black wire with plug). You will see a circuit board (whitish) that goes. Basically you are removing anything that connected to the old circuit. When you finish you will have just the two wires coming from the motor and two from the plugin leads. I went to the hardware store and purchased a $6 single pole single throw switch which I drilled a hole for in the top and mounted it there. The hookup is simple. One lead connects directly the the black motor wire. I used a twist on connector for this. The red wire connects to one side of the new switch. The plugin lead goes to the other switch side. There is insufficient room to use a twist connector so I soldered it instead. This makes a simple on-off circuit. Once done put it all back together. Plug it in, hit the switch, and the motor should rev up immediately.
    I only fill the hopper about 2/3 full when I grind because I do not want the motor to over heat. Obviously with no timer on board the grinder you need to monitor the grind and turn it off when it's done. Oh, and make sure you clean the chute carefully each time you use the grinder. If it's clogged it bogs the motor and shortens its life.
    This sounds like a time consuming task but other than the trip to the store it took about 30 minutes. I found a similar machine on Ebay for $28.00 but since the motor was still good I did not want to toss it. Stubborn, I guess. Good Luck!

This coffee maker (10 c maker with grinder) beeps it's done every few minutes with water left. we have to brew about 5 times for a full pot, what gives?

Presume this is the Grind & Brew Thermal™ 10-Cup Automatic Coffeemaker, Model # DGB-600BCC

An instruction booklet is available here:

Review the sections beginning on page 11 of the pdf on Turning Off the Grind Function (if not using the grind feature) and Making Coffee.

Make sure you are turning off the grind function if using preground coffee and that the reservoir lid is securely closed.

Check the Cups Setting button; is sounds like the 1-4 feature may be turned on.

Can this be fixed??? my grinder stopped grinding ????

Try to remove all coffee beans first by hand, then s*ck all remaining with a vacum cleaner.
Undjust the grinder to more gross coffee.
Try to work back again the grinder. If it is working then adjust back again to your previus postion but remeber that you can go back again one step at the time so the grinded coffee wil not blocked the grinding plates.
Good luck

Mine was doing that for the past week. I think it was indicating there had been a power outage but that the clock had not reset to zeros. I changed the time a couple of minutes and it stopped.

Coffee maker beeping

Is your grinder in and the lid down? My coffee maker (grind & brew) started beeping after I cleaned it and turned the left knob clockwise with the grinder still disassembled. There's a little button that is depressed when you close the lid with the grinder in there (I'd guess it's a safety feature). I pressed down that button, and the beeping went away.
