Troubleshooting
If you encounter issues with your MHW-3BOMBER Race M1 grinder, consider the following common solutions:
- Grinder is difficult to turn:
- Check if the grind setting is too fine. A very fine setting can increase resistance. Adjust to a coarser setting.
- Ensure no foreign objects are in the bean hopper.
- Clean the burrs thoroughly, as accumulated coffee oils and fines can cause resistance.
- Inconsistent grind:
- Verify that the grind adjustment dial is securely tightened to your desired setting.
- Ensure the burr is clean and free of obstructions.
- Check for any loose components after reassembly.
- No coffee grounds collecting:
- Confirm that coffee beans are loaded into the hopper.
