• Verify the power cord is fully inserted into a working 120V outlet and try a different outlet to rule out electrical issues
• Power off the machine completely and wait 60 seconds, then power back on to reset the system
• Remove and inspect the water tank—ensure it is clean, free of debris, and properly seated into the machine until you hear a click
• Fill the water tank with fresh, filtered water to the maximum fill line
• Check that the water inlet line on the back of the machine is not kinked, pinched, or disconnected
• Empty the drip tray and bean hopper; inspect for water pooling or blockages
• Remove the brew unit (if accessible) and rinse it thoroughly under running water, then reinstall securely
• Run a full descaling cycle using Miele-approved descaling solution per your user manual instructions to clear mineral deposits
• Inspect the inlet water filter (if your model has one) and replace it if clogged or discolored
• Ensure the machine is on a level, stable surface and not tilted
• Check the user manual for your specific USA model number to confirm water tank compatibility and proper installation
• If error persists after these steps, contact Miele USA customer service or a certified technician, as internal component failure may require professional repair
