Understanding the Causes of Grinder Clogs
Grinder clogs in your Breville Bambino Plus often result from a combination of factors. One common cause is using coffee beans that are too oily or moist, which can cause grounds to stick and accumulate inside the grinder mechanism. Additionally, grinding at an inconsistent or very fine setting can increase resistance, leading to jams. Over time, residual coffee oils and buildup can harden, obstructing the burrs and grinding chamber. Regular maintenance and mindful bean selection can help prevent these issues.
Another factor is infrequent cleaning, which allows oils and coffee particles to accumulate, eventually causing blockages that reduce grinding efficiency or stop the process altogether. Understanding these causes allows you to take proactive steps to maintain your machine’s performance.

Step-by-Step Guide to Clearing a Grinder Clog
- Unplug the machine: Always disconnect your Breville Bambino Plus from the power outlet before working on it to ensure safety.
- Remove the bean hopper: Gently lift the hopper off the grinder, taking care not to spill beans or grounds inside.
- Empty and clean the hopper: Wash the hopper with warm, soapy water and dry thoroughly to prevent moisture from entering the grinder.
- Disassemble the grind chamber: Carefully remove the upper burr and any accessible parts. Consult your user manual for specific instructions, as disassembly varies.
- Inspect for jams or blockages: Look for stuck coffee grounds, oil buildup, or damaged burrs. Use a brush or compressed air to clear debris.
- Clean all parts: Use a soft brush or a dedicated grinder cleaning brush to remove residual grounds. For stubborn buildup, consider using cleaning tablets designed for espresso grinders.
- Reassemble and test: Carefully put the grinder back together, fill the hopper, and run a test grind to ensure smooth operation.
Tips for Preventing Future Clogs
- Use the right beans: Opt for fresh, dry, and medium-roast beans to reduce oiliness and stickiness.
- Adjust grind size: Avoid grinding too fine; a slightly coarser setting can ease strain on the burrs.
- Clean regularly: Schedule monthly cleaning with grinder-specific tablets or brushes to prevent buildup.
- Store beans properly: Keep beans in an airtight container away from moisture and heat.
- Monitor machine performance: If you notice grinding slowdowns or unusual noises, perform a quick cleaning before it worsens.
