Machine displays 'Clean' or 'Service' indicating the brew unit cleaning program is due.

Safety first: Unplug the machine before removing the brew group.

Steps:

• Run cleaning program: Insert a Melitta cleaning tablet into the designated chute (often the pre-ground coffee chute) and start the cleaning program from the menu.
• Clean brew group: Remove the brew unit, rinse thoroughly under warm water, and let it dry. Lubricate moving parts with food-safe silicone grease.
• Clean coffee spouts: Use a small brush to clean the coffee outlet and spouts.

After the program completes, the indicator should clear. If not, consult the manual for manual reset steps.
