Step 2: Access the Grinder
- Remove the bean hopper by lifting it straight up.
- Carefully take out the burr chamber, following the user manual instructions for your model.
This step exposes the burrs and internal components for inspection and cleaning.
Step 3: Clean the Burrs and Grinder Components
- Use a soft brush or a dedicated grinder cleaning brush to remove coffee grounds, dust, and debris from the burrs.
- Wipe the surrounding area with a damp cloth, avoiding water contact with motor parts.
Regular cleaning prevents buildup that causes noise and inconsistent grinding performance.
Step 4: Check for Bean Jams or Misalignment
Inspect the burrs for stuck beans or debris. Clear any jams carefully, ensuring beans are not forcing the burrs out of alignment. If burrs are misaligned, gently reposition or tighten them according to the manual.
Step 5: Reassemble and Test
Reassemble all parts securely, replace the bean hopper, plug in the machine, and run a test grind. Listen for any irregular noises and observe if the grinding is smooth and quiet.
