How to Troubleshoot a Breville Bambino Coffee Machine

The Breville Bambino is a compact and user-friendly espresso machine, but like any appliance, it may occasionally run into issues. Here’s a quick troubleshooting guide to help you resolve common problems and keep your machine running smoothly.

1. Machine Not Turning On

  • Ensure the power cord is securely plugged in.
  • Check if the outlet is working by testing another appliance.
  • Press and hold the power button for a few seconds to see if it responds.

2. No Water Coming Out

  • Make sure the water tank is filled and properly seated.
  • Run a water-only cycle (without coffee) to clear any blockages.
  • Check the steam wand and group head for clogs and clean them if necessary.

3. Espresso is Weak or Watery

  • Use freshly ground coffee with a fine, even grind.
  • Ensure you are tamping with consistent pressure (about 30 lbs of force).
  • Clean the portafilter and filter basket to remove old coffee grounds.

4. Espresso is Too Bitter or Over-Extracted

  • Use a coarser grind to allow water to flow through more easily.
  • Ensure you are using the correct dose of coffee (usually 18–20g for a double shot).
  • Avoid brewing for too long—ideally, espresso should extract in 25-30 seconds.

5. Steam Wand Not Producing Steam

  • Ensure the steam wand is not clogged; clean it by running hot water through it.
  • Purge the steam wand before and after each use.
  • If the machine is in standby mode, turn it off and on again to reset the steam function.

6. Leaking Water

  • Check that the water tank is properly placed and not cracked.
  • Inspect the portafilter for a secure fit—tighten it if necessary.
  • Ensure the drip tray is not overflowing.

7. Descale Warning or Slow Performance

  • Regularly descale the machine using a Breville-approved descaling solution.
  • Clean the group head, portafilter, and steam wand after every use.
  • If the machine is still slow, backflush it using a cleaning tablet.

By following these steps, you can keep your Breville Bambino in top condition and enjoy consistently great espresso. If issues persist, consider reaching out to Breville customer support for further assistance.
