Troubleshooting Impact Grain Mill

If your NutriMill Impact Grain Mill is not performing as expected, use this troubleshooting guide to identify and resolve common issues. Proper maintenance and operation will help ensure the best milling results.

1. The Mill Won’t Turn On

Ensure the power cord is securely plugged in. Try a different outlet to confirm the power source is working.
Check if the motor has overheated. If the mill was running for an extended period, let it cool for at least 30 minutes before trying again.
Verify that the hopper is properly locked into place. The mill will not start if the hopper is not fully secured.

2. The Mill is Running, But No Grain is Milling

Ensure grain is flowing freely into the milling chamber. If grains are stuck in the hopper, stir them slightly to help them feed.
Check for clogs in the flour outlet. Turn off and unplug the mill, then use a brush or compressed air to clear any blockages.
Adjust the feed rate. If the mill is set too fine, grain may not enter the chamber properly. Turn the feed rate knob to a higher feed rate number and try again.

3. Flour is Too Coarse or Too Fine

Adjust the feed rate knob.
- Turn to a lower feed rate number for finer flour.
- Turn to a higher feed rate number for coarser flour.
Some grains naturally mill finer than others. If flour is coming out too fine, try a coarser setting or a different type of grain.

4. The Mill is Making Unusual Noises

Stop the mill immediately.
Check for foreign objects. Small stones or debris in grain can cause loud grinding sounds and damage the milling heads. Always use clean, inspected grain.
If the noise continues, inspect the flour outlet. A clogged outlet can create excessive strain on the motor.

5. The Mill is Overheating or Shutting Off Mid-Use

Let the mill cool for 30–60 minutes before restarting. Overheating can trigger an automatic shutoff to protect the motor.
Adjust the grind setting to a slightly coarser texture. Extremely fine milling can cause the motor to work harder and generate more heat.
Ensure the flour outlet is clear. A blockage can cause flour to back up, putting additional strain on the motor.

6. Flour Output is Slow or Uneven

Ensure grain is flowing smoothly from the hopper. Stir the grain slightly to prevent clumping.
Mill ¼ cup of white rice on a coarse setting. This helps clean the milling heads and remove residue buildup.
Check that the grains are fully dry. Moist grains can slow milling and cause buildup on the milling heads.

7. Flour is Leaking from the Canister

Ensure the canister lid is tightly secured. Make sure the filter and Cyclo Cup are properly in place.
Check for cracks or worn parts. If the canister lid or filter is damaged, replacement parts can be purchased from NutriMill Replacement Parts.
Clean the flour outlet regularly. A clogged outlet can cause excess flour dust to escape.

8. The Canister Lid is Hard to Remove

Unlatch the tab on the canister lid then pull up on the lid. A tight seal is normal but should not be excessively difficult to remove.
Tap the lid gently before removing. This helps release any vacuum seal caused by fine flour particles.

9. The Milling Chamber Appears Clogged

Mill ¼ cup of white rice on a coarse setting. This helps clean out residual flour buildup.
Turn off and unplug the mill. Use a dry brush to clean inside the milling chamber if needed.
Do not use water or liquid cleaners. Moisture can damage the milling components.
