The water inlet valve solenoid coils open to admit water from the household supply. A failed coil or clogged screen prevents water from entering the tub, triggering the IE (Inlet Error) fault code on LG top-load washers.
Mineral deposits inside the valve body or inlet screen restrict flow, causing the tub to fill far more slowly than the programmed cycle expects, leading to extended cycle times or mid-cycle stops.
A solenoid coil stuck in the open position allows water to flow continuously even when the control board is not requesting fill, causing the tub to overflow onto the floor.
Cracked valve body plastic or deteriorated internal seals allow pressurised water to drip or spray from the valve housing at the back of the machine, visually identifiable as pooling water behind the unit.
The multi-coil valve assembly also controls the bleach and fabric softener dispenser solenoids. A failed sub-coil within the assembly means additives are never flushed into the wash drum at the correct cycle stage.
💡 Pro Tip: Diagnosing a Faulty Washer Water Inlet Valve
Your part is likely the culprit if you notice any of the following:
⚠️ Washer displays IE error code (insufficient water fill)
⚠️ Tub fills very slowly or not at all despite good water pressure at the hose bib
⚠️ Washer overflows — valve solenoid stuck open and won't shut off
⚠️ Water leaking from the back of the machine near the valve housing
Quick test: Shut off the water supply and remove the inlet hoses. Inspect the internal mesh screens for heavy mineral deposits — a clogged screen mimics a failed valve. If screens are clear and the washer still won't fill, measure solenoid coil resistance with a multimeter (expected: 200–500 Ω per coil at room temperature). An open or shorted coil confirms valve replacement is needed.
