The blinking filter size light on your Breville machine is not just a random signal; it is an important indicator. This light typically starts to blink when the machine detects an inconsistency in the filter size or when there is a need for adjustment in the brewing process.

Common Reasons For Blinking

  • Improperly Attached Bean Hopper – The filter size light may also blink if the bean hopper is not correctly locked into position, a detail that is easy to overlook but crucial for proper machine function.
  • Incorrect Filter Size – If you have accidentally used a single-wall filter when the machine is set for a double-wall filter, or vice versa, the machine will alert you.
  • Clogged Filter Basket – Over time, coffee residue can build up, causing blockages.
  • Sensor Issues – Occasionally, the machine’s sensors might misread the filter size.

How To Fix The Issue: Simple Steps To Follow

Experiencing the blinking filter size light on your Breville espresso machine can be a minor hiccup in your coffee routine. Luckily, as you will see it is pretty easy to fix it.

Make Sure The Bean Hopper Is Attached Properly

The Breville machine’s filter size light may also blink if the bean hopper is not properly locked into position. This is an often overlooked aspect that can be confusing.

Make sure that the bean hopper is correctly inserted and securely locked on top of the machine.

How To Do This

  • Place the bean hopper onto the top of the machine.
  • Turn the dial to lock the hopper in place securely.
  • Make sure that the hopper is firmly attached. If it is loose, the filter light might start blinking, indicating an issue.

Note: The filter light may alternate between blinking for the single and double basket sizes if the hopper is not properly secured.

Verify The Correct Filter Size

Your Breville machine is designed to work with specific filter sizes. Using the wrong size can trigger the blinking light.

Check your machine’s manual to confirm the correct filter size for your model. Breville typically provides both single and double-wall filter baskets.

How To Check This

  • Open the group head and remove the existing filter basket.
  • Compare it with the images or descriptions in the manual to make sure it matches the recommended type for your desired brew.
  • If you have identified a mismatch, switch to the correct filter basket as per your brewing preference.

Clean The Filter Basket Thoroughly

Coffee oils and residues can clog the filter basket, affecting the machine’s functionality.

Regular cleaning of the filter basket is essential to maintain the machine’s performance and prevent the light from blinking.

How To Clean The Filter Basket

  • Knock out any remaining coffee grounds from the basket.
  • Soak the basket in warm, soapy water for a few minutes. Afterward, use a soft brush or sponge to gently clean it, and make sure not to use abrasive materials.
  • Rinse the basket thoroughly under running water and let it dry completely before reinserting it into the machine.

Restart The Machine

Sometimes, the machine may need a simple reset to recalibrate its sensors and clear any minor glitches.

A basic power cycle can often resolve sensor-related issues.

How To Restart Your Breville Coffee Machine

  • Power off your Breville espresso machine using the main switch.
  • Leave the machine off for a minute or two. Then, turn it back on to reset the system.
  • After rebooting, observe if the blinking light has stopped. This indicates that the issue has been resolved.

Contact Breville Support

If all else fails, the issue might be more complex, requiring professional intervention.

Contacting Breville’s customer support can provide more targeted solutions.

  • Have your machine’s model number and purchase details ready.
