Frequently Asked Questions - MHG Bunn
How do I adjust the grind setting on the Bunn MHG?
Turn the adjustment dial located on the front of the grinder. For finer grind, turn clockwise; for coarser, turn counterclockwise. Adjust while the grinder is running for best results.
Can I grind flavored coffee beans in the MHG?
Yes, but it is not recommended as the oils and flavorings can build up on the burrs and affect the taste of subsequent grinds. If you do, clean the burrs thoroughly after each use.
How often should I clean the Bunn MHG grinder?
Clean daily by brushing the burrs and removing the hopper for washing. Deep clean monthly using grinder cleaning tablets or a mixture of rice and cleaning solution.
What should I do if the grinder stops working?
Check the power cord and circuit breaker. Ensure the hopper is properly seated. If the motor runs but no coffee comes out, the burrs may be jammed. Unplug and remove the burrs to clear any blockages.
How do I replace the burrs on the MHG?
Unplug the grinder. Remove the hopper and grounds container. Use a hex key to loosen the burr retaining screws. Replace with new Bunn burrs and tighten securely. Reassemble in reverse order.
What type of coffee beans are best for the Bunn MHG?
Any high-quality whole bean coffee. Oily or dark-roast beans may require more frequent cleaning. Use a medium grind for drip coffee and fine for espresso.
Is the Bunn MHG suitable for espresso grinding?
Yes, it can produce a fine grind suitable for espresso, but it is a bulk grinder and may not offer the precise adjustments needed for specialty espresso. For consistent espresso, consider a dedicated espresso grinder.
How do I calibrate the timer on the MHG?
Access the timer board inside the grinder. Use the potentiometer to adjust the grind time. Refer to the manual for specific instructions. Typically, turn clockwise to increase time.
What is the typical lifespan of the Bunn MHG?
With proper maintenance, 10-15 years. Regular cleaning and burr replacement every 2-3 years extend the life.
Where can I find replacement parts for my Bunn MHG?
Authorized Bunn dealers or online retailers. Common parts include burrs, hopper, gaskets, and switches. Use genuine Bunn parts for best performance.
