Miele Coffee System Error Code F10

• Machine fails to start brewing cycle
• Coffee is not dispensed or only partial amounts are dispensed
• Error code F10 displays on the control panel
• Machine may make unusual sounds or no sounds during brew attempt
• Water drips slowly or not at all from the brew group
• Machine stops mid-brew and halts operation

• Water tank is empty, not properly seated, or the fill level is below the minimum line
• Clogged water inlet valve or distribution tubes due to mineral deposits from hard tap water common in USA regions
• Kinked, disconnected, or blocked water supply hose connection
• 120V power supply issue preventing proper pump operation
• Faulty pressure sensor malfunction
• Brew unit filter basket is clogged with coffee grounds or mineral buildup
• Water pump failure or inability to generate adequate pressure
• Internal water line obstruction requiring descaling

• Verify the power cord is firmly connected to a working 120V outlet and try a different outlet to rule out electrical issues
• Check that the water tank is filled above the minimum line and is clicked completely into place
• Remove the water tank, rinse it thoroughly, and reinstall it ensuring it seats properly
• Open the service door and visually inspect the brew unit area for standing water or visible blockages
• Empty and clean the drip tray, as overflow can trigger pressure sensors
• Remove the bean container and check for coffee beans blocking the bean chute or grinder
• Perform a complete descaling cycle using Miele-approved descaling solution and filtered water to remove mineral buildup
• Turn off the machine by switching the power button to OFF, wait 60 seconds, then switch back ON to perform a full system reset
• Run several brew cycles with just water (no coffee) to test water flow without obstruction
• If error persists after these checks, contact a USA-based Miele service center for warranty service
