Troubleshooting Impact Grain MillUpdated 13 days ago

If your NutriMill Impact Grain Mill is not working as expected, try the steps below. Always turn the mill off and unplug it before clearing a clog, inspecting parts, or cleaning.

The mill will not turn on

1. Confirm the power cord is plugged in and the outlet works.
2. Check whether the motor has overheated. If so, unplug the mill and let it cool for at least 30 minutes.
3. Confirm that the hopper is fully locked into place.

The mill runs but does not mill grain

1. Confirm that dry grain is flowing freely from the hopper.
2. Check the flour outlet for clogs. Turn the mill off and unplug it before clearing the outlet with a dry brush or compressed air.
3. Adjust the feed rate if the setting is too fine for the grain to enter the milling chamber.

Flour is too coarse or too fine

• Adjust the feed-rate knob lower for finer flour.
• Adjust it higher for coarser flour.
• Remember that different grains naturally produce different textures.

The mill is making unusual noises

1. Stop the mill immediately and unplug it.
2. Check the grain for rocks, metal, or other foreign objects.
3. Check the flour outlet for a blockage.
4. If the stones are rubbing, adjust the texture setting slightly coarser.

A slight scraping sound at the finest setting may be normal, but loud grinding or persistent unusual noise is not. Contact NutriMill Support if the noise continues.

The mill overheats or shuts off

1. Let the motor cool for 30–60 minutes before restarting.
2. Try a slightly coarser grind setting.
3. Confirm that the flour outlet is clear.
4. Use dry, clean grain and avoid oily or high-moisture ingredients.

Flour output is slow or uneven

1. Confirm that grain is flowing smoothly from the hopper.
2. Stir grain gently if it is clumped.
3. Mill 1/4 cup of white rice on a medium-coarse setting to help remove residue.
4. Confirm that the grain is completely dry.

Flour is leaking from the canister

1. Confirm that the canister lid is secured.
2. Check that the filter and Cyclo Cup are correctly installed.
3. Clean the flour outlet and remove buildup.
4. Replace cracked or worn parts rather than continuing to use them.

Regular maintenance

• Run the mill for a few extra seconds after milling to clear remaining flour.
• Tap excess flour from the canister filter.
• Brush the flour outlet and canister with a dry cloth or soft brush.
• Do not submerge or wash the milling unit with water.
• Store the mill in a dry location.

If these steps do not resolve the problem, contact NutriMill Support with your product model, a description of the issue, and photos or video when useful.
