What Causes Drip Tray Full Error?

Breville/Sage machines offer precise temperature control and pressure gauges for dial-in brewing.

Step-by-Step Fix

Follow these steps specifically for Breville Sage machines:

  1. Empty the Breville Sage drip tray. Wipe the metal contacts with isopropyl alcohol.
  2. Reinsert firmly until you hear a click. A loose tray triggers the full sensor.
  3. Check the microswitch. On Breville Sage machines, it can corrode from moisture.
