Safety Information
Please read all safety instructions carefully before using the appliance. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Always unplug the coffee grinder before cleaning it. This prevents accidental activation and potential injury.
- Ensure the coffee grinder, the power cord, and the plug remain dry. Do not immerse the appliance in water or other liquids.
- Do not use harsh detergents or abrasive scouring pads to clean the appliance. These can damage the surfaces and internal components.
- The lid-activated safety mechanism ensures that the blades only spin when the lid is securely in place. Do not attempt to bypass this safety feature.
- Keep out of reach of children.
- Do not operate the appliance with a damaged cord or plug.
Setup
Before first use, unpack all components and ensure all packaging materials are removed. Wipe down the exterior of the grinder with a damp cloth. Ensure the grinding chamber is clean and dry.
- Place the grinder on a stable, flat, and dry surface.
- Ensure the power cord is not tangled and is within reach of a suitable power outlet.
- Verify that the grinding chamber is empty and clean before adding ingredients.
Operating Instructions
The KRUPS Precision Electric Coffee Grinder features simple one-touch operation for efficient grinding.
- Fill the Grinding Chamber: Open the clear lid and add your desired amount of coffee beans, spices, herbs, or nuts into the grinding chamber. The grinder has a 3 oz (85g) capacity, sufficient for up to 12 cups of coffee.
- Secure the Lid: Place the clear lid firmly onto the grinder. The lid-activated safety mechanism ensures the grinder will not operate unless the lid is properly secured.
- Begin Grinding: Plug the grinder into a power outlet. Press and hold the button on the lid to start grinding. The blades will begin to rotate, processing the ingredients.
- Achieve Desired Consistency: The grinding time determines the fineness of the grind.
- For a coarse grind (e.g., for French press or cold brew), grind for a shorter duration (e.g., 5-10 seconds).
- For a medium grind (e.g., for drip coffee makers), grind for a moderate duration (e.g., 10-15 seconds).
- For a fine grind (e.g., for espresso), grind for a longer duration (e.g., 15-20 seconds).
- Empty the Grinder: Once the desired consistency is reached, release the button and unplug the grinder. Carefully remove the lid and pour out the ground ingredients.

Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the life of your grinder.
- Unplug the Grinder: Always ensure the grinder is unplugged from the power outlet before cleaning.
- Clean the Grinding Chamber: Use a small brush (often included with grinders) or a dry cloth to remove any remaining ground particles from the grinding chamber and around the blades. For stubborn residue, a slightly damp cloth can be used, but ensure the chamber is completely dry before next use.
- Clean the Lid: The clear lid can be wiped clean with a damp cloth. Ensure it is thoroughly dried before reattaching.
- Clean the Exterior: Wipe the exterior of the grinder with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
- Cord Storage: The compact design allows for easy storage. Wrap the cord neatly around the base if a cord wrap feature is present.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Grinder does not turn on. | Not plugged in, lid not properly secured, power outage. | Ensure the grinder is securely plugged into a working outlet. Check that the lid is fully and correctly seated on the base. Verify power supply. |
| Inconsistent grind. | Insufficient grinding time, too many ingredients, not pulsing. | Increase grinding time for finer results. Do not overfill the chamber. Use short pulses rather than continuous grinding for more uniform results. |
| Grinder overheats or stops during operation. | Continuous operation for too long, grinding excessively hard ingredients. | Allow the grinder to cool down for several minutes before resuming use. Avoid grinding extremely hard items that are not recommended for this appliance. |
| Excessive noise during operation. | Loose lid, foreign object in grinding chamber. | Ensure the lid is securely fastened. Unplug the grinder and carefully check for any foreign objects before restarting. |
