Remove the screws on the knob with the grind setting, that pulls out and gives you access to the burrs.

I have a Grindmaster model 805 coffee grinder. It worked flawlessly for many years, then suddenly stopped. I took it in to a repair facility and was told the switch had died. I had another machine at...


Most grinders, especially the larger professional models will eventually need to have the grinding wheels (set of 2) changed out. They do wear down. The grinder will struggle as the burrs on the wheel dull out. This increases the time it takes to grind coffee and puts a heavy electrical load. Burnt out switches, tripping breaker, overheating, and burnt coffee grounds on espresso size are all symptoms of a worn burr set.
It's common to find; stones, nails, jewelry, and small loose things found around coffee counters in the grinding wheels or burrs. Have a qualified operator remove all beans and hopper to check and brush out burr set. This should be done every day. Talk to your vendor if you find nails as they can easily correct this with a magnetic pick up.
Another cause is very oily beans. Sometimes poorly roasted beans come out extremely oily which will gum up everything from the burrs, Moving parts, and electrical components. Disassembly of entire machines may be necessary.
.Final note; since you mentioned a switch swap. It's possible the switch is underrated for use in this machine. Most will work in a pinch but like a 'spare' tire in a car, they are only ment to get you to a service center for replacement.

Coffee grinder wont start


Its been a while since i worked on a grind master so have a little patience with me. First, if the breaker went then there might be something blocking the burr chamber like a rock or screw or other obstruction. Second I would check the micro switch for the bag holder if there is one on your model using an ohms meter.

Whatever the setting is at the grind is always fine. What can I do to re-calibrate the grinder?


Grind Adjustment Tools required: Large blade and medium Phillips head screwdrivers In order to adjust the grind, follow these steps (Refer to figure A): 1. Remove all coffee from the hopper. 2. Set selector knob to the finest setting (Espresso or Turkish) depending on the model. 3. Loosen both knob retainer screws in selector knob one turn only. 4. While pressing the bag switch, located behind the spout, press the START button so that the grinder will run during adjustment. 810 model - Press the ON or START button so that the grinder will run during adjustment. 5. With the grinder still running, turn the adjusting screw in the center of the selector knob slowly to the right until a slight clicking noise is heard. Immediately turn the adjusting screw to the left one grind setting. This is the finest grind obtainable. 6. Tighten both of the knob retainer screws. Once the ESPRESSO grind has been set (Turkish for Model 835, 875, 890), the other grind settings will automatically set correctly. 7. Press the STOP or OFF button. IMPORTANT: Always be sure the grinding burrs are not touching while the machine is running on the ESPRESSO/TURKISH setting. Otherwise serious damage to the motor may result. dr_buckhead.png

With the dial turned to "Turkish" I still get a very course grind. How to adjust/fix?


On the adjusting knob there are 2 set screws (outside of the center) and an adjustment screw (the one in the middle). First make sure the LARGE screws on the side of the SELECTOR plate are tight. Start with the selector on Turkish, with the grinder OFF loosen the set screws about one full turn each. Leaving the selector on Turkish turn the grinder on and gradually VERY SLOWLY turn the center screw clockwise. Eventually you will hear the burrs inside touching. After they touch back of the center screw about 1/8 of a turn. Tighten the SET SCREWS tight as they may allow the grinder to go out of adjustment if not tight. Test the grind with very little coffee and throw those grounds out. Then grind and brew! If these grinders are adjusted too fine you may have problems with the grinds not falling and may back up.

Replacement part (exit chute)


I have not heard of a solution yet.... but I did download the manuals for the machine and have the parts numbers from different models which MIGHT be interchangeable.... I only paid $150 for the machine, so I am loath to spend too much more to solve my problem.
Might go on ebay...

Any three-pole momentary switch with the correct rating would work. Try Radioshack or the like.
Good luck.

Love your 'handle'!

I'm thinking that there is something in the burr in the unit. Empty the unit and remove the burr. Usually, this is done with a counterclockwise turn. Note how hard it may be to turn...you'll have to reverse this when you put it together. Now, clean out any coffee debris you find. Then, turn the unit over and tap it on a firm surface covered with newspaper. Reassemble and return to service.
