What This Part Is and Where It Goes

Part number 721580R010C0 is a door latch assembly used in Whirlpool and Maytag washing machines. It's the mechanism that holds the washer door closed during the wash cycle and releases when the cycle ends. When this part fails, your door either won't latch at all, won't unlatch, or latches intermittently — which stops the machine from running or traps wet clothes inside.

This assembly sits on the inside edge of the door frame, typically on the right side if you're facing the machine. It's one of the most commonly replaced parts on top-load washers because it takes the mechanical stress of repeated opening and closing over years of use.

Replacing it yourself takes about 30 to 45 minutes and requires only basic hand tools. The part itself costs between $40 and $80 depending on where you order it. A service call to have someone else replace it typically runs $150 to $250 plus the part cost.

Key Takeaways

  • You must unplug the washer and turn off the water supply before starting any work to avoid electrical shock or water damage.
  • The door latch assembly bolts to the inside of the door frame from behind the front panel, so you'll need to remove the front panel first to access it.
  • The part connects to the door strike (the catch on the door itself) and to the lid switch, so you need to disconnect both before removing the old assembly.
  • The new part comes with mounting hardware, but you should keep the old bolts if they're in good condition since they're often reusable.

Tools and Materials You'll Need

Gather these items before you start. You don't need anything specialized — most people have these already.

Tools: A Phillips head screwdriver, a flathead screwdriver (for prying), an adjustable wrench or socket set, and a flashlight or headlamp. A small container or bag to hold screws as you remove them prevents losing parts.

Materials: The replacement part 721580R010C0 itself. Have a towel or small bucket nearby in case water drips from the hoses when you move the machine slightly. You may also want a camera or phone to photograph the wire connections before you disconnect them — this makes reassembly much faster.

Disconnect Power and Water Before Opening the Machine

Unplug the washer from the electrical outlet. This is non-negotiable — the lid switch and door latch circuit carry current, and touching live wires can cause serious injury. Don't rely on turning the machine off; physically remove the plug from the wall.

Turn off the water supply valves behind the washer. There are usually two valves (one for hot water, one for cold) with handles you turn clockwise. This prevents water from spraying out if you accidentally bump a hose while working.

Open the washer door and let it sit open for a minute. This releases any pressure inside the tub and allows any residual water to drain slightly.

Remove the Front Panel to Access the Latch Assembly

The front panel is the plastic or metal trim piece that runs along the bottom front of the washer. On most Whirlpool and Maytag top-loaders, it's held on by three to five screws — usually Phillips head — along the bottom edge and sometimes one or two at the top corners.

Use your Phillips screwdriver to remove all visible screws holding the front panel. Keep these screws in your container. Gently pull the panel straight toward you; it may have clips or tabs on the sides, so don't force it. If it doesn't come free easily, check for screws you may have missed, particularly near the corners or under the lip of the panel.

Once the panel is off, you'll see the door latch assembly mounted on the right side of the door frame (when facing the machine). It's a rectangular metal or plastic housing with bolts going through it into the frame. You'll also see wires connected to it — these go to the lid switch and the door strike.

Disconnect the Wires and Remove the Old Assembly

Before you remove any bolts, photograph or sketch the wire connections. Most assemblies have two or three wires: one or two going to the lid switch (which tells the machine the door is closed) and one going to the door strike solenoid (which releases the latch). The connectors are usually straightforward push-on terminals that pull straight off.

Gently pull each wire connector away from the assembly. Don't yank on the wire itself — grip the connector and wiggle it side to side as you pull. If a connector is stuck, a small flathead screwdriver can help you pry it gently.

Now remove the bolts holding the assembly to the door frame. There are usually two or three bolts, each about 3/8 inch or 10 millimeters. Use your wrench or socket to turn them counterclockwise. As you loosen the last bolt, support the assembly with your other hand so it doesn't drop. Slide the assembly straight out toward you and set it aside.

Install the New Assembly and Reconnect Everything

Take the new part 721580R010C0 and position it in the same location where the old one sat. The bolt holes should align with the holes in the door frame. If they don't line up perfectly, the frame holes may need slight adjustment — this is rare, but if it happens, loosen the bolts slightly and wiggle the assembly until the holes align.

Insert the bolts through the assembly and into the frame. Tighten them by hand first, then use your wrench to snug them down. They should be tight enough that the assembly doesn't move, but you don't need to crank them hard — hand-tight plus a quarter turn is usually right. Over-tightening can crack the plastic housing.

Reconnect the wires in the same order they came off. Push each connector straight onto its terminal until you hear or feel a click. If you took a photo, use it to verify each connection is in the right place. Incorrect wire connections will prevent the door from latching or the machine from starting.

Reinstall the Front Panel and Test

Slide the front panel back into place, making sure any tabs or clips on the sides seat properly. Replace all the screws you removed and tighten them snugly — they don't need to be extremely tight, just find enough that the panel doesn't rattle.

Plug the washer back in and turn the water supply valves back on (turn counterclockwise). Open and close the door several times to make sure the latch engages smoothly and the door opens freely when you pull the handle. The latch should make a clear clicking sound when it catches.

Run a short test cycle (like a rinse and spin) without any clothes inside. Listen for any unusual sounds and watch to make sure the door stays latched throughout the cycle. If the door pops open, the latch didn't seat properly — unplug the machine and check that all wires are fully connected and all bolts are tight.

Frequently Asked Questions

Can I replace just the strike or solenoid instead of the whole assembly?

On some older models, yes — the strike (the catch on the door) and solenoid (the electromagnet that releases it) are separate parts. However, on most modern Whirlpool and Maytag machines, 721580R010C0 is a complete assembly and those components aren't sold separately. Replacing the whole assembly is usually the only option.

What if the door still won't latch after I install the new part?

First, check that all wire connectors are fully seated — a loose connection to the solenoid will prevent the latch from engaging. Second, verify the door strike on the door itself isn't bent or misaligned. If the strike is damaged, it may need replacement too. If both the latch and strike look fine, the lid switch wiring may have an issue — this requires a multimeter to test.

Do I need to replace the door strike at the same time?

Not unless it's visibly cracked, bent, or worn. The strike is a straightforward metal or plastic piece that the latch catches onto. If the new latch assembly doesn't engage smoothly, inspect the strike for damage. Most of the time a new latch assembly alone solves the problem.

How long does this repair take if I've never done it before?

Plan for 45 minutes to an hour your first time. Once you've done it once, you can repeat it in 20 to 30 minutes. The longest part is usually photographing the wire connections and carefully disconnecting them — take your time there and you'll avoid mistakes during reassembly.

What should I do with the old latch assembly?

If it's still mechanically sound but just worn out, some appliance repair shops will take it as a core exchange and credit you a few dollars. Otherwise, it can go in the trash. Don't try to repair it — the solenoid and strike mechanism inside can't be fixed if they've failed.
