How to Replace W11130743 Dishwasher Water Inlet Valve on Whirlpool KitchenAid — Step-by-Step

You load the dishwasher, hit start, and... nothing. No water rushing in, just silence. That's exactly what happened to a KitchenAid owner who replaced their W11130743 water inlet valve — only to discover a fork wedged under the float valve blocking water flow. Before you order parts, check that float first. But if your valve's actually failed (leaking connections, weak water flow, or complete silence), here's how to swap it in under 15 minutes.

What You Need Before Starting

This is one of the easier dishwasher repairs. The valve sits right in front, usually behind the lower kickplate. You'll need:

• Phillips screwdriver
• Pliers (for hose clamps)
• Towel (for water drips)
• Small bucket or pan

Repair Time: Less than 15 minutes
Difficulty: Easy

Safety First

Turn off water supply to the dishwasher at the shut-off valve under your sink. Unplug the dishwasher or flip its breaker — you'll be working near electrical connections. Water and electricity don't mix. Even with power off, expect some water to spill from the lines when you disconnect them, so keep that towel handy.

Step 1: Access the Water Inlet Valve

Remove the lower kickplate at the bottom front of your dishwasher. Most models use two or three screws. With the plate off, you'll see the valve on the left side where the water line enters. It's got two hoses attached and one wire harness. On models like the WDT750SAHZ or KDFE104DBL, it's immediately visible.

Step 2: Disconnect Water Supply and Wiring

Use pliers to loosen the compression fitting where the supply line connects to the valve. Water will drip — that's normal. Next, disconnect the wire harness by pressing the release tab and pulling straight out. Finally, use pliers to squeeze the spring clamps on the two internal hoses and slide them back. Pull the hoses off the valve nipples. More water will drip here.

Step 3: Remove the Mounting Screw

One Phillips screw holds the valve bracket to the dishwasher frame. Remove it and the entire valve assembly lifts out. That's it. On a MDB4949SDM or WDF520PADM7, this screw is obvious once the hoses are clear.

Step 4: Install the New W11130743 Valve

Position the new valve in the same orientation as the old one. Install the mounting screw finger-tight, then snug it with your screwdriver — don't overtighten. Slide the two internal hoses back onto the valve nipples until they seat fully, then reposition the spring clamps over the connections. Reconnect the supply line and tighten with pliers. Finally, plug in the wire harness until it clicks.

Step 5: Check for Leaks Before Reassembly

Turn the water supply back on slowly. Check all three connections for drips. If you see water, tighten the compression fitting or reposition the hose clamps. Once everything's dry, restore power and run a short test cycle. You should hear water rushing in within 30 seconds.

Testing After Installation

Run a rinse cycle and listen. The valve should open with a distinct click, followed by water flow. Check underneath during the first few minutes for any leaks. If water fills normally and you don't see drips, you're done. Replace the kickplate and you're back in business.

Frequently Asked Questions

My dishwasher still won't fill after replacing the valve — what else could it be?

Check the float assembly in the tub bottom. One user found a fork wedged under theirs, preventing water from entering even with a new valve. Also verify your water supply valve under the sink is fully open. If the valve hums but no water flows, you might have a clogged inlet screen where the supply line connects.

Can I use this valve on Maytag and Kenmore dishwashers too?

Yes. The W11130743 replaces WPW10327249, W10327249, and W10316814 across Whirlpool, KitchenAid, Maytag, Kenmore, and Amana models. It fits MDB4949SDM Maytag units and dozens of Whirlpool models like the WDT710PAYM. Check your model number against the compatibility list to confirm.

How do I know if the valve is bad or if it's a different problem?

If you hear clicking but no water enters, the valve's likely failed closed. Leaking around the valve connections means internal seals are shot. If the dishwasher fills slowly or stops mid-cycle, the valve solenoid might be weak. No sound at all when starting suggests either no power to the valve or a control board issue — test the valve with a multimeter for continuity first.
