The grinder will not start

The grinder motor does not start when the on/off button is depressed. There is no obvious way to take the thing apart.

Check the mechanism is not blocked, undo the screws at the front. Remove the baseplate, there is a 1.25 a fuse attached to it under a black plastic cover. If neither of these thing work, is there a burning smell?
Could be the motor. I imagine it is just the fuse.

My Cuisinart DCG-12BC coffee grinder, the bowl is stuck on the motor base. It works and turns, but it will not come apart to be able to clean it. Please advise.


.... mine stuck after "first" use ... solution ... took it back to the store, got a refund, bought a Mr. Coffee Model IDS77 which was $11. cheaper, has automatic grind settings and a superior bowl arrangement... Then I put Cuisinart on my list of DO NOT BUY ... anything can have problems, but something obviously this chronic should be handled better by the manufacturer ... it should have been taken off the market and fixed ...

Tip

If it doesn't work, it may be the On/Off switch.


I have had this grinder for a number of years. About 3 years ago we moved and upon arrival I plugged it in, loaded some beans and pressed the on button - Nothing. Now I know a little bit about these things & I was sure it was not the motor. I completely disassembled the Burr Grinder. It comes apart by removing the rubber feet on the bottom, then removing the screws under the feet. The top part comes apart by removing the screw from the 4 corners (it is easiest if you remove the timer board first). You need a long Philips screwdriver. Before you do this, make sure you are comfortable messing with electronics etc. The last screw to remove the top is under the grind catcher area directly underneath the timer rheostat. Once I had the top off, there is a small circuit board with the timer rheostat (a liner rheostat, not circular) and the On/Off switch. I measured the resistance of the On/Off switch and there was no difference when I pressed the button, obviously a bad switch. The switch is a small, about0.170" thick switch. I was able to find a switch at Radio Shack that was actually the same except it was thinner. I unsoldered the old switch and found a little piece of solid rubber used for gluing on the bottom of something you don't want marred. It was about 0.95", so it raised the new switch up just enough to make contact with the button on the lid when it was pressed. Attached wires to the new switch, soldered it in, put it back together,and fired it up. Works like a charm.

My Cuisinart CCM-16PC suddenly decided not to burr/grind coffee. It doesn't turn on. Electrical recepticle is hot and the device is plugged in. I've cleaned all of the connections/buttons/grooves so...


Same thing happened to me about 1 year ago. I took the machine apart and determined the issue to be in the circuit board. I bypassed the board and wired the power cord directly to the motor. The machine began to work and is still operating fine. The only drawback, of course - having bypassed the circuit board and switch, you now are on full manual operation. Plug the power cord into the wall outlet and the motor spins; when you are finished grinding you have to remove the cord from the power source to stop the motor. I am OK with this - beats 35 - 50 dollars for a new grinder. Dave

There is a second switch, similar to the user accuated switch, which is opposite the user accuated switch when viewed from the bottom of the unit. This second switch is controlled by a piece of plastic which fails when the device overheats. I am currently seeking to replace that part on my unit.To fix the problem you will need to replace this part so that the second switch is closed. Both of the two switches on the bottom of the unit must be closed in order for the unit to operate.

I can't get the removalable bowl off the grinder. I think the blades are stuck.


This seems to be a widespread problem on units manufactured in 2007 and later.

Unplug the unit from the AC outlet. Remove the six screws that hold the lower plastic cover on the motor base (four screws are hidden under the adhesive rubber footpads). This exposes the lower end of the motor shaft, which has a slot in it. By inserting a flat blade screwdriver into the slot and holding the cutting blades with a rag or a wad of paper towel to avoid cutting one's fingers, it is possible to twist the shaft back and forth about 90 degrees. You may need another person to help, because one needs to perform this twisting action while pulling the motor base away from the grinding cup and blade assembly.

Once you get the @&%$#! thing apart, reassemble the motor base. (With the slotted motor shaft, why didn't the designers simply put a hole in the plastic base so one could stick a screwdriver in without disassembling it?) Plug it into the wall outlet and use a small object like a toothpick or matchstick to activate the recessed motor switch so you can spin the motor without the grinding cup in place. Use the blunt edge of a small snap-blade utility knife as a scraper to gently scrape the plastic pin of the motor shaft as it spins, much as one would work a wood turning lathe. Periodically check the fit of the brass hub of the grinding cup on the plastic pin. Continue to shave the pin until the grinding cup slips onto and off the pin with no resistance. Take care to machine the pin uniformly from top to bottom; avoid making grooves.

Why this mechanism worked properly when my grinder was new about 18 months ago and suddenly decided to get stuck this week is a bit of a mystery. The unit in question has been used since it was purchased exclusively to grind flax seed, but the ill-fitting pin normally doesn't come into contact with foods, anyway. There was no obvious evidence of swelling of the plastic due to heat from the motor or oils from seeds. Since the blade and hub are free to travel up and down on the plastic motor shaft pin a bit, I suspect that on occasion the blade doesn't settle properly and the clutch doesn't engage, allowing the pin to spin in the brass bushing until it starts melting, and then the hub settles so that the clutch is fully engaged. This may happen in a matter of just a couple of seconds of operation. Once that happens, the pin conforms to the microscopic grooves inside the brass bushing, allowing it to still turn slightly relative to the motor shaft, but locking it on so that it can't come apart. If Cuisinart had made the pin more tapered and the hole in the brass bushing to match, much like a Jacobs taper on an industrial drill press spindle, this would be much less of a problem.

BOTTOM LINE: Before loading the grinding cup and starting the grinder, push the blade hub down with your finger to make sure the clutch is fully engaged.

There are four slots in the bottom through which you can see the attachment clips. These clips are not mounted on the base but clip into the base. There is a special 4 prong tool that is used to depress these but if you don't have one, which you most certainly will not have, you need to use four small nails to open it up. Looking at them from the bottom, the clips look like a capital E with an extra horizontal leg. try to drive your nails in to the middle of the back of the E, that is on the flat side. After you have done this use a claw hammer to pry the bottom off by inserting the claws into the seam between the bottom and the top and twisting until something gives. You will probably get the bottom off without destroying more than one of the clips. No matter, you can tape or glue the ****** back together.

If power lose was your problem, remove the switch from its clip then test it to see if depressing the button causes the contact rod to touch both of the copper plates which are mounted on opposite sides of the switch, be careful while making this test - you have to have the grinder plugged in and you do not want to be touching any electrical contacts, the blade or the motor. Also beware of the torque from the motor causing you to drop the grinder. Also, beware of the torque from the motor causing you to drop the grinder in the unlikely event that it is working.

If depressing the switch doesn't cause the switch shaft to come in contact with both plates then get a pair of plyers and bend the copper plates down so that contact can be readily be made.

Retest to confirm the fix works then reassemble, using tape, glue or whatever and then -- it's coffee time!!

Noise


The top of the unit that covers the coffee beans has a plastic point that must depress a button on the main body of the unit when it closes to show the unit that the lid is closed properly. If this is broken (as was mine) I inserted the end of a piece of tooth pick replacing the plastic point in the lid and this now depresses the recessed button on the main unit. The beeper goes off and the on light comes on.

I had the same problem, took it all apart, separated the two halves, and looked into the guts of the machine, not an easy task. Fiddled with this and that, and looked at the back of the switch mechanism, and heard it making a 'click' when depressed, so put it all back together, to no avail...It turns out the grinder needs to have two limit switches engaged, one between the lid of the ground coffee hopper and the underside of the grinder hopper housing, and the other between the grinder lid and the base of the unit. This last limit switch was my problem, it seems the lid wasn't making contact with the limit switch, so the unit didn't run. I cleaned out the narrow gap that the grinder lid sits within, pressed the lid down until I heard a small 'click' , pressed the on switch, and presto! it works. You can see this very tiny switch if you take off the grinder lid, and look in the narrow gap it sits in at a position of about three o'clock ( the back of the machine when viewed from the top being 12 o'clock. Hope this helps anyone else who can't find their receipt within the one year warranty period. This is the best burr grinder I've found for the money, and I'm glad mine's still o.k.

Take apart


My grinder went from bad to worse and finally stopped grinding (with the motor still buzzing but absolutely no grinding). Knowing I had to do something or throw it away, I pulled the clear plastic bean reservoir upward and separated it from the grinder body. I looked down the hole where beans go down to the grinder and found packed coffee ground blocking the hole. I cleaned the whole thing, put the reservoir back, and my grinder now works like new :-)
