Baratza.com sells the timer switch for $10 plus $10.58 shipping and handling. I initially called Starbucks and they gave me the old " we don't sell parts but we will sell you a new one".

I just had the same problem. It's the knob itself. You have to extract the knob by pulling, gently, and squeezing it out. The plastic housing over the metal thing is cracked. I took some super glue and duct tape and wound it tightly around it and pushed it back it and it works.

    I had same problem - twice!! My coffeee grinder is a Dualit EL60, with the Faucigny Instrument type Mi3 timer.
    To set the timer, you turn knob clockwise - if you turn other way, it jams in the 'on' position. I found ron t6's info helpful; when I took machine apart, plastic housing was fine, but the timer switch was jammed. It does come apart with gentle encouragement from a small flat blade screwdiver ;-) It is quite fiddly to put it all back together, but possible!!
    Try not to lose the tiny flat piece of metal that falls out when you first take the timer knob out!!!
    The second time I repaired it (tonight) I took some pix which I intend to post on my website.

How can I fix / remove the timer knob?


The timer probably was damaged.

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 conical burr coffee grinder has started to turn it's self on every few hours


Electronic failure. If you like the grinder, plug it into a plug-in timer that only allows it to run when YOU want it to run. I have a timer like that on my coffeemaker so we don't forget to turn it off & let it run empty all day long. There are cheap timers available that will turn on for three hours if you push a little button, then shut off until next time you push the button. VERY handy, and they give you a selection of one hour, three hours, or six hours. For your purpose, one hour sounds fine. Or a wind-up type timer that stays on for only fifteen minutes, just long enough to grind coffee. Or unplug it when you're done. Or put it on a power strip with a switch.

My grinder just stopped grinding... turned it on, heard a "Chunk" sort of sound and it stopped grinding. Timer works and light comes on but no grinding. I also cannot unscrew the top portion to look and...


  • DIAGNOSIS

  • it can be too tight stringed at burrs
  • some stone or metal part with coffee went between burs
  • IF IT IS AUTOMATIC, it can be one of 2 micro-switches or main relay, in this case you have power but only to middle of way.
SOLUTIONS

  1. Release the burrs, grind one amount coffee with bigger granulation than go back again carefully.
  2. Disassemble the upper burr holder and clean carefully, all coffee and remains put in one plate, inspect with magnet, hand and than put all that in water. (heavy parts fell down fast in water)
  3. Check the switches and relay:
  • Upper micro-switch has an plate and one box where it is( box might be full of coffee or the plate blocked and giving the signal of full doser every time)
  • Lower micro-switch should activate every 6th pull of doser(he is below in mechanism of doser)
  • Relay gets power from micro-switches when they command. even we switch on if the commandsof micro-switch says off than relay will not obey us.

Grind is like powder


There are 3 springs in the holes around the top neck of the machine, the top part which sits under the collar adjustment knob.

Motor stopped working


Hi
There is a thermal fuse on the side of the motor to prevent the motor from burning up. You can replace the fuse (it is a 103c thermal fuse, crimp it on ) and you should be in for more grinding.
It could also be you timer switch, or bean hopper switch, or a broken tab on your adjustment collar.

The two small little guides you refer to are a pair of switches that get depressed when the top is pressed down. In the top is supposed to be a plastic pin in the top of each one of the grooves. When both pins push both of the switches down (look like black dots) the grinder wil operate. The proper solution would be to replace the top.

Open the grinder by removing both knobs.
The front knob is held in place by friction. Use two flat head screwdrivers to pry it off.
The side knob is held in by tabs you have to push. Pry forward to expose the tab, and use another screwdriver to press the tab, and use the other screwdriver to press the tab on the other side.
Now look at the bottom of the grinder. There are four tabs on the outer shell, use screwdriver s to pry the tabs to separate the bottom of the grinder from the shell, and pull off the shell. Your fuse should be attached to the motor wiring coil.
