Troubleshooting Classic Grain MillUpdated 13 days ago

If your NutriMill Classic 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. Turn the lower Grain Feed Rate Knob slightly to the right if it is fully turned left in the off position.
3. Press the red Circuit Reset Button on the bottom of the milling module.
4. If the mill still will not start, stop troubleshooting and contact NutriMill Support.

The mill runs but does not mill grain

1. Confirm that dry, clean grain is in the hopper.
2. Open the lower Grain Feed Rate Knob enough to allow grain to flow.
3. Turn the mill off and unplug it before checking the grain inlet for a clog.
4. Gently shake the mill to loosen stuck grain. Do not use water or liquid cleaners.

Flour is too coarse or too fine

• For finer flour, turn the upper Motor Speed Control Knob to the left.
• For coarser flour, turn it to the right.
• For finer flour, set the lower feed-rate knob around 11:00–12:00.
• For bread flour, start around 12:00–1:00.
• Different grains naturally produce different textures, so adjust gradually.

Flour is leaking from the bowl or lid

1. Confirm that the separator cup is securely attached.
2. Make sure the air filter is installed, dry, and not clogged.
3. Confirm that the flour bowl lid is sealed correctly.
4. Check the gasket and clean away flour buildup.
5. If the leak continues, check whether the lid, gasket, separator cup, or filter needs replacement.

The mill is clogging or making unusual noise

1. Stop the mill immediately and unplug it.
2. Check the grain for rocks, metal, or other foreign objects.
3. Confirm that the separator cup and flour bowl lid are assembled correctly.
4. Use only dry grains. Moist or oily ingredients can cause buildup and clogs.
5. After clearing the issue, mill three cups of white rice on a coarse setting to remove residue.

If loud grinding, burning odor, or unusual noise continues, stop using the mill and contact NutriMill Support.

The mill overheats or shuts off

1. Turn the mill off and let the motor cool before restarting.
2. Reduce the grain feed rate slightly.
3. Use completely dry grain and confirm that the flour outlet and filter are clear.
4. Do not re-mill flour that has already been milled.

Regular maintenance

• Empty the flour bowl and separator cup after each use.
• Tap excess flour from the air filter and brush away residue.
• Mill three cups of white rice on a coarse setting periodically to clean the milling heads.
• Store grain in a dry place and never use water on the milling module or milling heads.

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.
