Display shows E9; unit may not fill with water or may overfill the reservoir.

Safety: Turn off power and close the water supply shutoff valve before servicing the inlet valve.

Steps:

• Pull the unit out enough to access the rear where the water line connects to the Marvel ice maker.
• Disconnect the water supply line and inspect the inlet screen on the valve for sediment or debris. Clean or replace the screen as needed.
• Verify that household water pressure to the unit is adequate (typically 20–120 psi). Correct any supply issues.
• Remove the access panel to expose the water inlet valve. Inspect for signs of leakage or corrosion.
• With power disconnected, test the valve coil resistance with a multimeter. Compare to Marvel specifications. Replace the valve if the coil is open or shorted.
• Restore power and, using caution, check that the valve receives proper voltage when the unit calls for fill. If it has voltage but does not open, replace the valve.
• After installing a new Marvel water inlet valve, reconnect the water line, check for leaks, and run a test cycle to confirm proper filling and that E9 clears.
