Troubleshooting Harvest Grain MillUpdated a month ago

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

1. The Mill Won’t Turn On

✔ Ensure the power cord is plugged in securely – 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 secured – If the hopper is not locked in place, the mill may not function.

2. The Mill is Running but No Grain is Milling

✔ Confirm the hopper contains grain – Sometimes grain may not flow if it is clumped or packed too tightly. Stir the grain to loosen it.
✔ Adjust the texture control knob – If the stones are too close together, grain may not enter the milling chamber properly. Turn the knob counterclockwise slightly and try again.
✔ Inspect for clogs – Turn off the mill, unplug it, and check the flour spout for blockages. Use a dry brush or compressed air to clear any obstructions.

3. Flour is Coming Out Too Coarse or Too Fine

✔ Adjust the texture control knob –

• For finer flour, turn the knob clockwise.
• For coarser flour, turn the knob counterclockwise.
  ✔ Different grains may produce different textures – Some grains naturally mill finer than others. Experiment with settings for the best results.
  ✔ If the flour is too fine and causing overheating, mill at a slightly coarser setting.

4. The Mill is Making Unusual Noises

✔ Turn off and unplug the mill immediately.
✔ Check for foreign objects in the grain – Rocks or debris can cause loud grinding noises and damage the millstones. Always use clean, inspected grain.
✔ If the stones are rubbing against each other, adjust the texture control knob slightly counterclockwise. A slight scraping noise at the finest setting is normal, but a loud grinding sound is not.

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

✔ Allow the motor to cool – If the mill shuts off due to overheating, let it rest for 30–60 minutes before restarting.
✔ Adjust the grind setting – Very fine flour requires more motor power. Try a slightly coarser setting to reduce strain.
✔ Ensure the flour spout is not clogged – Blockages can cause flour to back up, straining the motor. Clean out the spout using a brush or compressed air.

6. Flour Output is Slow or Uneven

✔ Check the grain flow – If the hopper is too full, grain may not flow evenly. Stir the grain to prevent clumping.
✔ Mill 1 cup of white rice on a coarse setting – This helps clean the milling stones and remove any residue buildup.
✔ Ensure grains are completely dry – Moist or oily grains can slow milling and cause buildup on the stones.

7. Excess Flour Buildup Around the Mill

✔ Clean the flour spout – Excess flour may indicate a clogged spout. Use a brush or compressed air to remove blockages.
✔ Ensure the hopper lid is secure – This helps contain flour dust during milling.

8. The Millstones Appear Glazed or Clogged

✔ Mill 1–2 cups of white rice on a coarse setting to clear residue from the stones.
✔ Do not use water or liquid cleaners – Moisture can damage the milling stones.
✔ Use a dry brush to clean the milling area if residue remains after milling rice.

By following these troubleshooting steps, you can resolve most common issues with your NutriMill Harvest Grain Mill.
