Machine displays 'Empty grounds container' even when it is empty and reinserted.

Step 1 – Properly reset the container:

• With the machine on, remove the drip tray and grounds container.
• Wait 10 seconds, then reinsert both fully until they click into place.

Step 2 – Clean the sensor area:

• Clean the area where the container slides in; remove any coffee residues.

Step 3 – Power cycle:

• Turn the machine off and unplug it for 5 minutes, then restart.

Step 4 – Inspect the container and sensor (advanced):

• Check the container for a broken plastic tab that actuates the sensor; replace the container if damaged.
• With the housing removed (unplug the machine first), test the sensor or microswitch and replace it if faulty.
