Machine shows B2 and the used capsule drawer icon flashes; brewing is disabled.

Safety first: Turn OFF and unplug the machine before reaching into the capsule area.

Step 1 – Empty and clean the drawer

• Remove the used capsule drawer and empty all capsules.
• Rinse the drawer with warm water and dry thoroughly.
• Check for deformation or cracks that might prevent proper insertion.
• Reinsert the drawer fully until it seats correctly.

Step 2 – Check for obstructions

• Inspect the drawer cavity for stray capsules or debris.
• Remove any obstruction that could prevent the drawer from closing fully.

Step 3 – Sensor inspection (advanced)

• Unplug and remove the cover to access the drawer sensor area.
• Locate the drawer microswitch or magnetic sensor.
• Check that the actuator (tab on the drawer) properly engages the switch when inserted.
• Adjust or replace the switch if it does not click or change state when pressed.

When to seek service

• If B2 remains after confirming the drawer and sensor are mechanically sound, the sensor wiring or control board input may be faulty and should be checked by a technician.
