Symptoms
• Machine displays E07 error code on the control panel and stops brewing
• No water flows through the coffee outlet or only weak water flow
• Machine beeps or makes unusual grinding sounds before displaying the error
• Steam wand produces little or no steam when attempting to froth milk
• Machine may power off unexpectedly or freeze during operation
• Water drips slowly from the brew outlet or not at all
• Display screen may show the error repeatedly even after machine restart
Possible Causes
• Mineral scale and hard water deposits blocking water lines (common in USA regions with high mineral content)
• Clogged or blocked water pump due to accumulated sediment or mineral buildup
• Faulty water pressure sensor failing to register proper system pressure
• Kinked or disconnected internal water tubing
• Water pump motor malfunction or electrical connection failure
• Brew unit not properly seated, preventing water flow through the coffee outlet
• Malfunctioning inlet valve restricting water entry into the system
• Air lock in the water system preventing proper water circulation
• Defective pressure switch or relief valve in the brewing circuit
Safety Checks You Can Do
• Unplug the machine from the wall outlet and wait 60 seconds, then plug it back in to perform a hard reset
• Check that your home circuit breaker has not tripped; if it has, reset it and try the machine again
• Verify the water tank is completely filled with fresh, cold filtered or bottled water and is properly seated in its position
• Remove and reinsert the water tank firmly to ensure proper connection and water line engagement
• Run a full descaling cycle using a commercial descaling solution designed for USA coffee machines to remove mineral deposits common in hard water areas
• Inspect the drip tray and grounds container for overflow or blockage; empty and clean both thoroughly
• Check that the brew unit (if removable) is clean and properly inserted all the way into the machine until it clicks or locks into place
• Look into the bean hopper to ensure beans are present and not jammed; shake the hopper gently if beans appear stuck
• Examine the water outlet and steam wand openings for visible mineral buildup or blockages; if you see white crusty deposits, descaling is needed
• Ensure the machine is placed on a level, stable surface and not tilted or leaning
• Try running a test shot of hot water only (without coffee) to isolate whether the issue is with water flow or the brewing mechanism
• Check that all external water connections and hoses (if your model has them) are not pinched, kinked, or disconnected
Safety First
Always disconnect the appliance from power before performing any checks. If you are unsure about any step, please contact a qualified technician.
