Symptoms
• Machine fails to dispense water or coffee into the cup
• Water flows weakly or intermittently during brewing
• Error code E02 displays on the machine's control panel
• Machine halts mid-brew cycle and stops responding
• Water may leak from underneath the machine or into the drip tray
• Grinding function works but no water reaches the brew group
• Machine beeps repeatedly and locks out all brewing functions
Possible Causes
• Mineral scale buildup in water lines due to hard water common in many USA regions
• Water tank not properly seated or inserted into its housing
• Clogged or partially blocked water inlet filter or supply tube
• Low water pressure from the home water line or empty water tank
• Faulty water level sensor or pressure switch malfunction
• Air trapped in the water system preventing proper flow
• Defective water pump unable to generate adequate 120V/60Hz operation pressure
• Brew group positioning sensor issue or misaligned brew unit
• Internal water line disconnected or cracked inside the machine
Safety Checks You Can Do
• Power off the machine completely and check your home circuit breaker to ensure the outlet is functioning properly
• Unplug the machine for 60 seconds, then plug it back in to perform a hard reset
• Remove and reinseat the water tank, ensuring it clicks fully into place and is filled with fresh filtered water
• Empty the drip tray and grounds container to check for overflow or blockages
• Run a full descaling cycle using a commercial descaling solution designed for coffee machines to remove mineral buildup from USA hard water
• Inspect the water inlet area on the back of the machine for any visible damage or disconnected tubes
• Open the brew unit door and verify the brew group is fully inserted, locked in place, and free of coffee grounds or debris
• Check the bean hopper for empty beans or jammed beans that may prevent the machine from operating
• Allow the machine to sit for 10 minutes after descaling to ensure water lines are fully flushed
• Run a test brew cycle with just water to confirm water flows normally before making coffee
