This Part Fixes These Problems

Dishwasher Won't Fill

The dishwasher starts a cycle but no water enters the tub. A failed solenoid coil in the inlet valve prevents it from opening, starving the wash system of water.

Dishwasher Underfills

The tub fills partially but not to the correct level, resulting in poor wash performance and food residue left on dishes after a full cycle.

Water Leaking Under Dishwasher

A cracked valve body or failed internal seal allows water to drip or pool beneath the appliance even when the unit is off — a clear sign the valve must be replaced.

Dishwasher Hums But No Water

The fill solenoid is receiving power and humming, but a stuck or seized valve stem prevents water from flowing into the tub.

IE or 4E Error Code Displayed

Samsung dishwashers throw an IE (or 4E) water inlet error when insufficient water is detected during the fill stage, often caused by a faulty inlet valve rather than water supply pressure.

💧
Precise Water Flow ControlSingle solenoid coil design controls water intake with consistent pressure, ensuring proper fill levels every cycle and preventing both overfill and underfill conditions.

⚖️
Lightweight & CompactWeighs only 0.19 lbs (3.98" × 3.07" × 2.20") — identical form factor to the Samsung OEM unit, fitting into the original mounting bracket without any trimming or adapter required.
🔩

💡 Pro Tip: How to Confirm Your Water Inlet Valve Has Failed

Your part is likely the culprit if you notice any of the following:

⚠️ Dishwasher does not fill with water at the start of a cycle (IE error code on Samsung models)

⚠️ Dishwasher underfills — dishes come out with dried food residue despite completing a full wash cycle

⚠️ Water drips or pools under the dishwasher when the unit is not running — valve body seal has failed

⚠️ Dishwasher hums at fill stage but no water enters the tub — solenoid coil is energized but valve is stuck closed

🛠 Diagnostic tip: With the dishwasher unplugged and water supply shut off, disconnect the inlet hose and check the valve screen filter for mineral buildup. If the screen is clear but the valve still fails to open during a cycle, the solenoid coil has failed — replace the valve assembly. A multimeter test across the solenoid terminals should read approximately 200–500 Ω on a healthy coil; an open or shorted reading confirms failure.
