Symptoms
• Machine stops mid-brew cycle and displays E14 on the digital display
• No water flows from the group head or brew outlet during coffee extraction
• Weak or no coffee output despite beans being ground and loaded
• Hissing or unusual sounds from the water pump area
• Machine may power on but refuse to start a brewing cycle
• Water tank appears full but machine indicates a water problem
• Error message remains even after attempting to brew again
Possible Causes
• Mineral scale and calcium buildup in the water lines from hard water common in many USA regions blocking water flow
• Water tank not fully seated or inserted properly in its cradle
• Water inlet valve or filter blocked by debris or sediment from tap water
• Faulty water pump unable to generate sufficient pressure on 120V/60Hz electrical system
• Kinked, cracked, or disconnected water supply tube inside the machine
• Brew unit not correctly installed or seated in its position
• Pressure sensor malfunction preventing the machine from detecting adequate brewing pressure
• Empty water tank not triggering the fill sensor correctly
Safety Checks You Can Do
• Check that your home circuit breaker for the outlet is in the ON position and the outlet itself is providing power by testing with another appliance
• Remove the water tank completely, rinse it thoroughly with fresh tap water, and refill with cold filtered or bottled water to the MAX line
• Reinsert the water tank firmly into the machine cradle ensuring it clicks or locks into position
• Run a full descaling cycle using a commercial descaling solution designed for coffee machines to remove mineral buildup from 120V heating elements and water lines
• Power off the machine, wait 60 seconds, then power it back on to perform a hard reset and clear any temporary sensor errors
• Open the brew unit access door and verify the brew unit is fully inserted and locked in place with no gaps
• Inspect the drip tray and grounds container for overflow or blockage and empty them if full
• Check the bean hopper to ensure beans are not jammed, the hopper is properly seated, and fresh beans are loaded
• Visually inspect any visible water tubes inside the machine access areas for kinks, cracks, or disconnection and gently straighten any kinked tubing
• Attempt a test brew with water only (no beans or grounds) to isolate whether the issue is with water delivery or the grinding/brewing process
Safety First
Always disconnect the appliance from power before performing any checks. If you are unsure about any step, please contact a qualified technician.
