This valve sits underneath the top panel, at the point where the cold water supply hose connects, and it's the gatekeeper for cold water entering the tub. When the control calls for a cold fill, it energizes the valve's solenoid to open, admitting water; once the correct level is reached, it closes again. This part controls the cold water side specifically — hot fills on these washers are governed by a separate valve.\u003c\/p\u003e\n\u003cp\u003eRated 12V and terminated with small male spade connectors, this valve measures approximately 4.75\"H x 3.25\"W x 2.25\"L, with a gray plastic and metal housing. Over time, rust and mineral buildup inside the valve body — a documented failure point on this platform — can prevent it from sealing fully, which lets water continue flowing even after the valve is told to close. A washer that keeps filling even while draining, or that leaks steadily at the cold connection, is a strong sign of exactly this kind of stuck-open valve failure. Other failure modes include a burned-out solenoid coil and general wear from age. It directly replaces 4869496, AP6798394, PS12587936, and EAP12587936, and is also cross-referenced to the related 5221ER1003A part number.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-qa\"\u003e\n\u003cp class=\"pom-qa-label\"\u003eQuick Answer\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eXPARTCO 5221ER1003S Washer Water Valve\u003c\/strong\u003e fixes LG and select Kenmore front-load washers where cold water won't fill, fills slowly, keeps filling continuously (even while draining), or leaks at the water connection. 12V cold water inlet valve, small male spade terminals, 4.75\"H x 3.25\"W x 2.25\"L.

Wear work gloves. Pull the washer away from the wall for access. Unthread the cold water supply line from the back of the valve first — have a towel ready, since residual water will spill out. Unthread the two screws securing the top panel, then slide the panel back and lift it off to access the valve assembly underneath. Photograph the wiring connections before disconnecting anything. Disconnect the spade terminal wire connectors from the old valve, remove its mounting screw or bracket, and pull the valve free. While it's out, inspect the area for rust or mineral scale, and clean the connection point if needed before installing the new valve. Install the new 5221ER1003S in the same position, reconnect the spade terminals, and secure the mounting hardware. Rethread the cold water supply line onto the new valve, tightening securely. Reinstall the top panel and its two screws. Restore the water supply and power, then run a short cycle and confirm the tub fills at the normal rate with no leaking underneath or behind the washer. Tools needed: channellock pliers, flathead screwdriver, pliers, drill\/driver with a Phillips bit, towel, work gloves.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-card\"\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eMy washer keeps filling even while it's draining. Is that this valve?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eYes, this is a well-documented failure mode on this platform. Rust and mineral buildup inside the valve body can prevent it from sealing fully closed, so water keeps trickling or flowing into the tub even after the fill portion of the cycle has ended — sometimes enough to keep pace with draining, making it look like the washer is filling and draining simultaneously.

Rust and mineral buildup on this valve is a known precursor to it sticking partially open, which can lead to continuous filling, water waste, and potential water damage if it isn't caught.
