So the first thing you want to do is unplug the washer for 60 seconds and plug it back in to see if the latch will reset. If that doesn't work, listen closely and if you hear a motor running/humming--just leave the washer plugged in for 20 minutes and the washer should reset on it's own and unlock.
The most likely cause is an inoperative drain pump, or a clogged debris filter. If your washer has water inside the Drum, the door will not open to prevent a flood. If you are using to sanitize the cycle and the water is extremely hot, the door will not open to prevent injury.
Power Off/On: Turning off the machine and unplugging it for a few minutes, then plugging it back in and restarting it, could reset the machine and unlock the door.
Perform a Reset: Turn off the washing machine and unplug it from the power source. Wait for about 10 minutes, then plug it back in and turn it on. This can sometimes reset the machine and release the door lock. Manually Drain the Machine: If there is water remaining in the drum, you may need to manually drain it.
To remove a lock washer, use a wrench or a similar tool to remove the nut or threaded fastener that holds the lock washer in place. Next, use a flathead screwdriver to pry the lock washer loose. If you remove a split washer, place the screwdriver head under the washer or inside the split.
To fix a stuck key, apply a lubricant such as graphite powder or a silicone-based spray to the keyhole. Gently wiggle the key while pulling it out. If this doesn't work, use a pair of needle-nose pliers to grip the key and carefully work it out.
Washer Control Reset
To reset the electronic controls on your washer, shut off the circuit breaker or fuse to the washer or unplug the washer for 2 minutes. For models that have a timer control knob, turn the knob around and back to any position other than final spin for the interrupted cycle. Then, restore power.
Water left in the machine is also a common cause of a locked washing machine door. Running a spin/drain cycle can often fix this issue, but if it fails, the machine may need to be drained manually. The door catch, handle, or some part of the door catch mechanism may be broken, preventing the door from opening.
Normally waiting for the cycle to end is all you need to do to unlock the door, or turn your washer on if it's off. If you get stuck, though, you can drain the water from front load washers using the emergency drain hose; once the water is gone, the door will unlock.
You should just need to press and hold the "Control Lock" button for 5 seconds to remove the control lock. If that doesn't work, unplug the washer for 5 minutes and plug it back in. The electronics get glitchy sometimes and won't reset. After reapplying power, try to hold the "Control Lock" button again for 5 seconds.
Some common fixes for washing machines that won't drain include performing a master reset, testing the lid switch assembly, and clearing clogged drain hoses and pumps.
Press the “Control Lock” button on your Whirlpool washer for three seconds. After three seconds, you should be able to open the door. If the door still doesn't open, press the “End of Cycle” button (if your washing machine has one) for five seconds.
To reset the washer control panel, it needs to be disconnected from the power source for one minute. If your washer is plugged into an outlet, simply unplug the unit for one minute and then plug the unit back in.
Use a can of compressed air or a small brush to clean the keyhole thoroughly. Lubricate the lock: Sticky locks are often due to a lack of lubrication. Apply a graphite-based or silicone-based lubricant specifically designed for locks. Avoid using oil-based lubricants as they can attract more dust and grime.
First, try keeping the machine turned off for five minutes, then try opening the door again. If this doesn't fix the issue, you can gently strike the door over the area where the lock is with the palm of your hand. This can sometimes activate and release the lock.
Unplug the machine and wait a few minutes. Most doors will open once the power is off and the temperature cools off. Try knocking gently on the handle or pressing the pause/start button. Loop fishing line around the locked door and pull away from the door to manually unlock the locking mechanism.
Turning off the machine at the mains should allow the door lock to cool down, and after a few minutes, you'll be able to open the washing machine door. The interlocks can take some time to release at the end of the cycle, so be patient. The most common cause is water left in the machine. Try running a spin/drain cycle.
Detach the drain hose from the back of your washing machine. Use a funnel to pour about a quarter of a cup of baking soda into the pipe. Next, empty a baster full of vinegar into the drain hose. Top tip: If the blockage is not completely gone, you can repeat the above process.
If the machine gets stuck mid-cycle, try stopping it, draining the water and rearranging the laundry. The problem could be that the drum is overloaded. As a rule, you should fill it no more than three quarters. If the items are really heavy, it's best to fill it less.
