Whirlpool Duet Washer Door Locked Humming – Troubleshoot And Diagnosis

Whirlpool Duet Washer Door Locked Humming

There are several potential reasons that a Whirlpool Duet washer might have a locked door and make a humming sound. Let’s discuss each one by one.

1. Check Door Latch

One of the most common causes of a Whirlpool Duet washer with a locked door and humming sound is a faulty door latch. The door latch is responsible for holding the door closed during the wash cycle, and if it is damaged or not functioning properly, it can cause the door to lock and the machine to make a humming sound.

 The most likely explanation for this sound is the door latch being stuck in an open position, meaning it doesn’t close properly and consequently causes humming from its motor as it attempts to spin.

This can be caused by a broken part or an item that may have gotten stuck in the latch. It’s important to check for any debris or objects that may be blocking it from engaging correctly before attempting to repair it yourself.

If there is nothing obstructing the latch, then it could be due to a damaged internal component such as a worn-out gasket or spring, or even corrosion building up on some parts inside the washer door.

To solve this, you should check if the door latch has become misaligned or jammed due to overuse, dirt buildup or any other issue. If all else fails then you may need to replace the entire unit with a new one as parts of these types of washers are usually not sold separately at stores.

Proper maintenance and repairs can help prevent future occurrences but if symptoms persist even after replacement then consider contacting your local appliance repair service provider for further assistance.

2. Clogged Drain Line

A Whirlpool Duet Washer humming with a locked door can be an indication of a clogged drain line. If your washer is making loud, persistent sounds while the door won’t open, this could mean your drain line needs to be cleared.

Clogs in the drainage system are often caused by lint or dirt buildup over time and will eventually become severe enough to block water flow completely.

To avoid further damage, it’s best to take action as soon as you suspect there may be an issue. Start by unplugging your washer from its power source for safety reasons before accessing the back panel where you can inspect and clear any clogs that have accumulated within the unit’s drainage pipe.

Once all blockages have been removed, plug in your machine again and attempt to run another load; if everything works correctly then congratulations on fixing what could’ve been a costly repair!

3. Control Panel Issue

The first step is to check the wiring harness. Make sure all the wires are connected properly and that there are no loose or damaged wires. If the wiring harness looks good, then you’ll need to reset the control panel.

You can do this by pressing and holding the “start/stop” button for three seconds. If the door still won’t open and the humming continues, then you’ll need to replace the control panel.

Replacing the control panel isn’t as hard as it sounds. You’ll need to disconnect the power first. Then, you’ll need to remove the screws that hold the control panel in place and carefully pull the panel away from the wall.

After that, you can replace the panel with a new one, making sure to connect all the wires before powering it back on.

4. Actuator Motor

The Whirlpool Duet Washer Door Locked Humming noise is a common issue and usually occurs due to an Actuator Motor problem.

The Actuator Motor is responsible for locking and unlocking the washer door, as well as controlling cold and hot water supply during the wash cycle.

A malfunctioning Actuator Motor can cause the washer to produce a loud humming noise when you try to open the door.

In most cases, this issue can be resolved by checking if there are any loose or damaged wires connected to the Actuator Motor. If everything looks okay, then it’s possible that your Actuator Motor has become faulty and needs replacing.

To determine if this is indeed the case, you should refer to your user manual and consult a qualified technician.

5. Drain Pump Issue

If you own a Whirlpool Duet Washer and it has suddenly stopped working, then you might be experiencing a drain pump issue. This issue is characterized by the washer door being locked with a humming sound coming from the machine.

The cause of this problem is usually blocked drainage or an overload of debris that clogs up the pump.

Fortunately, there are some simple steps to diagnose and fix this issue on your own.

The first thing to do if your Whirlpool Duet Washer isn’t draining properly is to check if there’s any debris in the drain hose or filter screen. If debris is present, remove it as soon as possible before continuing on with other troubleshooting steps.

Afterward, unplug the machine from power and inspect for any loose wiring connections or corroded parts within the washer’s motor housing. If you’re still having issues, try cleaning the pump filter screen, which is located on the back of your washer, as it could be clogged with lint or other debris.

If you’re still having an issue and the washer is no longer under warranty, you can contact Whirlpool customer service for assistance.


A Whirlpool Duet Washer Door Locked Humming issue can be both irritating and concerning. While it may seem like an intimidating problem to tackle, taking the time for troubleshooting steps can save you a call to a professional.

Simply checking the drain hose, resetting the washer, removing any foreign objects blocking the door latch mechanism or using external power source can usually get your washing machine back up and running in no time at all!
