Whirlpool Washer Water Inlet Valve Parts — Models & Compatibility

Your Whirlpool washer won't fill with water, or maybe it's filling too slowly and your wash cycles are taking forever. The water inlet valve controls the flow of both hot and cold water into your machine — and when it fails, you're stuck with a washer that can't do its job. This hub covers the W11210459 water inlet valve replacement for Whirlpool top-load washers, including compatible models across Whirlpool, Maytag, Kenmore, and Amana brands.

Is This the Right Part for Your Model?

The W11210459 valve fits most Whirlpool top-load washers manufactured from 2010 onward, particularly the WTW4600, WTW4800, and WTW4900 series. You'll find your model number on a sticker inside the washer lid or on the back panel near the top. Cross-reference it with the compatibility list below — this valve also replaces older part numbers AP6329217, W10701459, W10838319, W10869799, and W11025984, so if you're holding an old invoice or parts list, those are all the same valve.

About This Replacement Part

The water inlet valve is an electrically-controlled solenoid valve that opens when the washer's control board sends power to it during the fill cycle. It connects directly to your home's hot and cold water supply lines and has internal screens that filter debris. Over time, mineral deposits from hard water can clog these screens or the solenoid coils can burn out, causing slow fills, no fills, or continuous water flow even when the washer's off. The W11210459 is a direct OEM-equivalent replacement with the same mounting bracket, electrical connector, and hose fittings as your original valve. You'll need to shut off the water supply, disconnect the inlet hoses (keep a towel handy — there's always residual water), remove two screws holding the old valve, swap the electrical connector, and reverse the process. Most repairs take 20-30 minutes once you've got the back panel off.

Compatible Whirlpool Washer Models

This valve works across multiple Whirlpool series and related brands. The list below shows the most common models, but the actual compatibility extends to over 100 model variations:

• WTW4616FW0, WTW4616FW1, WTW4616FW2
• WTW4715EW2
• WTW4810EW1, WTW4810EW2
• WTW4815EW1, WTW4815EW2
• WTW4816FW0, WTW4816FW1, WTW4816FW2
• WTW4850HW0
• WTW4855HW0, WTW4855HW1

If your model starts with WTW46, WTW47, WTW48, or WTW49, there's a strong chance this valve will fit. Always verify the part number match before ordering.

Why Whirlpool Inlet Valves Fail

Hard water is the main culprit. Calcium and lime buildup gradually restricts water flow through the valve's internal screens and passages. You'll notice this as longer fill times first — what used to take three minutes now takes eight or ten. Eventually, the valve may not open fully or might stick partially open, causing leaks when the washer's supposedly off. The solenoid coils can also fail electrically, especially if you've had power surges or voltage fluctuations in your home. A failed valve won't click when the washer tries to fill, and you won't hear the familiar rush of water entering the tub.

Ordering the W11210459 Valve

The replacement valve costs $63.99 and ships with the mounting bracket and electrical connector pre-installed. Make sure you've got your model number handy when ordering — while this valve fits dozens of models, Whirlpool made running changes during production years, and confirming compatibility saves you a return trip. If you're in a hard-water area, consider installing an inline water filter on your supply lines to extend the life of your new valve.
