Restore rapid filling cycles, precise automatic water levels, and peak washing performance with this Genuine OEM LG Washer Water Inlet Valve Assembly. This factory-certified dual solenoids module (Part # 5221ER1003S, which officially replaces older or alternative distribution codes like 1327189, AP4437731, AH3522941, and PS3522941) serves as a primary fluid controller managing household water entering your appliance.

This specialized dual-valve manifold layout features two independent, electronically controlled solenoids mounted to a unified thermoplastic body. When your washer’s main control board advances to specific stages of a laundry cycle—such as the initial wash fill or the rinse phase—it routes a 120-volt electrical signal to the targeted solenoid coil. The resulting magnetic field lifts an internal rubber diaphragm piston, allowing pressurized tap water to rush through that specific port and directly into the tub.

If mineral scaling, rustic pipe sediment, or fine sand flakes choke the internal mesh filters, or if an unexpected winter freeze splits the plastic housing, the module will fail. This triggers immediate system faults, including a washing machine that stops mid-wash and flashes the “iE” or “1E” (Inlet Error / No Fill) code, long and slow filling cycles, or a slow, continuous trickle of water that leaks into the drum and pools overnight while the machine is turned completely off.

Quick Info:

• Compatibility: Precision engineered for modern, high-efficiency (HE) front-loading and top-loading LG and Kenmore (796-Series) washing machines.

• Component Design: Dual-solenoid configuration containing a single threaded utility male hose intake, dual barbed plastic outlet distribution nozzles, and standard two-pin male spade electrical terminals.

• Fixes Common Issues: Resolves “iE” or “1E” water fill error codes; long, slow filling cycles; failure to pass water during specific rinse or wash phases; and internal weeping leaks that cause the washer tub to slowly fill with water when idle.

• Difficulty: Novice to Intermediate. A highly accessible DIY repair situated directly at the back corner of the upper chassis frame, requiring basic hand tools.

⚠️ Frontline Diagnostic Step: Check the Mesh Screen First!

Before unboxing and swapping out your entire inlet valve assembly, perform a quick 5-minute inspection to confirm that it isn’t simply choked with local plumbing sediment:

1. Turn your household utility wall faucets completely off and unscrew your fill hoses from the back of the washer.

2. Look directly inside the plastic threaded intake of the valve. You will see a fine blue or white mesh cone filter seated inside the opening.

3. If this screen is blanketed in brown rust scale, sand, or hard calcium pebbles, the water cannot physically pass through. Use needle-nose pliers to gently pull the screen out, scrub it completely clean under a tap with an old toothbrush, snap it back in, and test the machine. If the “iE” code persists or the solenoids hum loudly without letting water through, the valve is internally defective and must be replaced.

Step-by-Step Replacement Guidelines:

1. Absolute Safety Isolation: You must completely unplug the washing machine’s electrical power cord from the wall outlet to eliminate all high-voltage shock hazards. Turn both household water utility faucets tightly clockwise to completely shut off the water supply lines.

2. Disconnect the Supply Hoses: Place a small bucket or old towel underneath the hose connections at the back of the machine. Use slip-joint pliers to unscrew the water fill hose from the threaded intake port.

3. Remove the Main Panel Cover: Unthread the two Phillips head retaining screws holding the rear edge of the washer’s top flat sheet-metal plate. Slide the top cover panel backward about an inch, lift it up, and set it aside to expose the internal valve layout at the upper rear corner of the chassis.

4. Disconnect Wiring and Internal Hoses: Take a picture of the wiring arrangement with your phone for clear reference. Use your fingers or a flat tool to unclip the wire harness plug connectors from each solenoid terminal block. Use pliers to squeeze and slide back the tension wire clamps on the rubber outlet hoses attached to the inner nozzles, then twist the hoses firmly off the valve body.

5. Unbolt and Swap the Valve: From the outside rear cabinet wall, unthread the mounting screws securing the plastic valve body mounting ears directly to the metal panel structure. Slide the failed valve assembly inward and pull it completely clear. Position your fresh new genuine factory valve assembly in its place, anchor it from the back panel with your mounting screws, slide the interior rubber distribution hoses back onto their matching nozzles, slide the wire clamps securely back into position, and snap the color-coded electrical terminals firmly back onto their corresponding solenoids.
