• Verify the machine is plugged into a functioning USA 120V outlet and power indicator light is on
• Unplug the machine and wait 60 seconds, then plug back in to perform a complete system reset
• Remove and inspect the water tank—ensure it is completely filled with fresh, filtered water and properly seated until it clicks into place
• Check that the water tank inlet port and machine connection point are clean and free of debris
• Empty and rinse the drip tray thoroughly, then reinstall to ensure proper drainage
• Open the brew unit access door and visually inspect for any visible blockages, coffee grounds, or debris
• Remove the bean container and check for blockages or jams in the bean hopper and grinding chute
• Run the cleaning cycle if available on your model, using Miele-approved cleaning tablets to flush the system
• Perform a descaling cycle using Miele descaling solution following your user manual instructions, as mineral buildup is common in many USA water supplies
• Ensure all external hoses and water connections are not kinked, pinched, or disconnected
• If error persists after these steps, contact Miele Customer Service at 1-800-999-1360 or visit the USA Miele website for warranty service
