    My DBM-8 slowed and then stopped grinding three days ago, after 2 years' ownership. cuisinart does not offer any repair service or recommendations. not exactly a "green" company in my book, expecting me to toss it into a landfill and buy another. if anybody has any experience in repairing such a problem let us know. i'm going to try disassembling it this weekend.

    I think it is the switch on the ground coffee bin but I can't find any parts site.

We are on our second and last machine; after this DBM 8 goes out, I am going to find the most basic grinder I can and stick with it. That said, I fixed ours by removing the clear plastic reservoir where the ground coffee ends up, and then removing the build-up of coffee grounds around the exit chute where the ground beans enter the reservoir.
So, slide the reservoir out, just as you would when emptying it in to your coffee maker and set it aside. Have a flashlight ready when you tilt the grinder forward. On the back side you will see the hole where the ground beans empty into the reservoir. Take a toothpick and get rid of all the clay-like coffee reside that has built-up around that hole. Use a can of dusting air, if possible, (the aerosol "can" type used to blow dust particles from your computer) and blow away all possible ground coffee residue in the hole and around it. This will allow the reservoir to seat snug and flush again. This process fixed ours and I don't know why for sure, other than I suspect, the clay like build-up of coffee grounds, over time prevents the reservoir from seating properly and it has to seat perfectly to work. Good luck.

I took this solution one step further with my DBM-8. I removed the bottom cover and found the 4 screws at the corners (you need a long Phillips head screw driver) and removed them enabling me to take the top off the machine. This way I was able to get into the grinding chamber itself. That clay like buildup that Marc mentioned was all around the burr wheel. I scraped it all out as best I could then reassembled it and it worked better than it had in a while.

    To add to Jason6486 after struggling with this tonight. You will need to completely unscrew (counterclockwise) and remove the hopper before removing the 4 screws. Also, to remove the bottom cover, there are screws under the rubber footpads. Plus there is a 5th screw in the grind catcher area directly underneath the timer switch. After cleaning out all the old grinds and vacuuming the timer switch like Jason6486 suggests, the grinder runs like a top.

I bypassed the switch the detects the bean hopper, but cutting the red wire connecting it directly to power. Works fine now

Marc's suggestion may be right on. i did just that a few weeks ago. disassembling from the bottom hoping to ID fried wires at least, i noticed built up very fine grounds and cleared it with a small jewelers screwdriver. not finding any wiring problem, i had given up and reassembled but tried it one more time and voila, it worked!
again, i don't think i will support cuisinart, a company lacking both customer support or a repair service. surely they must know such a problem may occur.

I have the same unit it has been flaking out for a while. Seems to be a switch problem, I have cleaned , poked, prodded this thing nothing seems to be a real solution so much for trusting consumer reviews. I had a DeLonghi grinder that took 10 years to break why can't I find that model again ?

How do i clean dbm-8 grinder


Do yourself a favor and got the right kind of grinder for the coffee you drink. If you have a dry coffee use a grinder. High oils in some coffee need the blade type of grinder. Usually you can tell by looking inside the bad. See oily coating get a blade type.

Mine did it as well. I had an electrician out to check out the outlet. He replaced the outlet, but it still has done it. It freaks me out, so I unplug it after use.

Coffee does not go from grind to brew basket. Plugs..must clean every time


Try running some unflavored panko breadcrumbs or rice through it. That will clean it up and remove any oil that's causing sticking. Try to use less oily coffee in the future to avoid this.

perhaps remove the hopper (top) and inspect to see if a buildup of very fine compacted grounds as accumulated. knock the stuff loose.

Cuisinart burr grind and brew coffee maker


The hopper between the burr grinder and where coffee chutes into the filter is jammed with coffee powder...

First, take out the filter holder and carafe, and place a freash empty filter on the pot base to catch stuff.

Next, take out the beans holder and look for the release lever in the lower left section. Sliding it to the left slides open the door, where you'll probably find loads of powder. You can poke your finger through to get the majority, then use the cleaning brush to get it really clean.

Thanks what fixed mine! (I notice I have to do this about once every few months.)
