GE Washer Not Filling With Water: Error 18, Valve Screen, and SmartDispense

Quick Answer

GE washer not filling displays Error 18 (water fill timeout). GE Profile with SmartDispense: the auto-dispensing system needs water to function - if the washer won't fill, SmartDispense also fails. Check both supply valves and inlet screens. GE-specific: Error 18 can also trigger from very low water pressure (below 15 PSI). GE front-loaders with UltraFresh: the inlet valve is behind the rear panel.

GE front-loaders with UltraFresh: the inlet valve is behind the rear panel. GE top-loaders: the valve is at the top rear. GE uses a single-piece valve with multiple solenoids - if one solenoid fails, the valve assembly must be replaced ($25-50).
