Display shows E7; unit may not fill with water or may overfill the ice-making tray.

Safety first: Unplug the unit and shut off the water supply (for plumbed-in Galanz ice makers) before servicing.

Steps to address E7:

• Check water supply: Verify that the water supply valve to the ice maker is fully open and that household water pressure is adequate.
• Inspect supply line: Look for kinks, sharp bends, or leaks in the water line. Straighten or replace as needed.
• Clean inlet screen: Remove the water inlet valve from the back of the unit and clean any debris from the inlet screen using a small brush.
• Test valve operation: With a multimeter, check the coil resistance of the inlet valve. An open coil indicates a failed valve that must be replaced.
• Flow sensor (if present): Some Galanz models use a flow sensor. Inspect it for mineral buildup and clean or replace if it is stuck.
• Reassemble and test: Restore water and power, then run a cycle to confirm proper filling.

When to call a technician: If the valve receives power but does not open, or if the control board is not sending power to the valve, professional diagnosis is recommended.
