Household appliances generally don’t make noise unless it’s trying to bring your attention to a problem. The same is true with an LG dishwasher that stops mid-cycle and starts beeping. If that’s happening to you, you’ve come to the right place.

Generally, your LG dishwasher will stop mid-cycle and beep if the door has been opened. The same will happen if the dishwasher thinks the door is open, like when the door latch or catch is faulty. However, suppose the door and its components are alright. In that case, the mid-cycle stopping and beeping are likely because the main control board has failed.

Check out the guide below to understand more about why this problem is happening and what you can do to get it sorted out quickly.

Why Does My LG Dishwasher Stop Mid-Cycle And Beep?

Generally, your LG dishwasher will stop mid-cycle and start beeping because something has happened with the door. More specifically, the door has either been opened, or the appliance mistakenly thinks that the door is open.

The machine stops to prevent injury or damage caused by the spinning wash arms inside. Plus, it also prevents water from spraying all over your kitchen floor.

As for the beeping, that’s the dishwasher’s way of catching your attention to let you know there’s a problem.

Here’s what you’ll want to consider while troubleshooting this problem:

Someone Opened The Dishwasher Door

What’s happening: A complete troubleshooting process can take time and effort. So, it’s best to rule out the simplest causes first.

In this case, the first thing to check is whether or not you or someone in your household opened the dishwasher door. This might have been done on purpose (e.g. by someone wanting to check the contents inside), or it might have happened by accident (e.g. you accidentally pulled the door open).

Whatever the reason, pulling your LG dishwasher door open will stop it mid-cycle and cause it to start beeping.

How to solve it: When you open the dishwasher door mid-cycle causing it to stop and beep, the appliance behaves precisely as it was programmed to. 

You don’t have to do anything to fix the issue except close the door and allow your dishwasher to finish its current cycle.

Defective Door Latch

About this: The door latch is a crucial component for your LG dishwasher’s door. It’s a component that sits above where the door closes.

The door latch has switches in it that sense when the dishwasher door is closed. So, when you close the door, the switches will send electrical signals to let the appliance know that it’s safe to begin the dishwashing cycle.

Opening the door for any reason will cause the door latch to do the opposite: to tell the dishwasher to stop mid-cycle and trigger the beeping noise you hear.

What’s happening: Opening your dishwasher door will release the switch inside the door latch. As you saw in the previous section, that’ll cause the appliance to stop mid-cycle and start beeping.

However, the same can happen even if you didn’t open the dishwasher door. That’s because the door latch and the switches inside have become defective.

A defective door latch will cause your LG dishwasher to mistakenly sense that the door is open. Then, the dishwasher will stop in the middle of whatever it’s doing and beep to warn you of the problem.

How to solve it: The door latch and the switches inside can’t be repaired if they are defective. So before you spend money on replacements, you should test the door latch for electrical continuity.

You can do that using a standard multimeter.

Once you confirm that one or more of the switches in the door latch is defective, you’ll then have to purchase a new door latch entirely.

Then, you can disconnect the existing one and install the replacement.

Faulty Door Catch

About this: The catch is another critical component in your LG dishwasher’s door. That part is attached to the dishwasher’s door. 

So, when you close that door, the catch will meet with the latch, and your dishwasher can sense that it’s safe to proceed with the dishwashing cycle.

Unlike the dishwasher door latch, the catch isn’t an electrical component. It doesn’t have switches or wiring and doesn’t send electrical signals to the dishwasher.

What’s happening: The dishwasher door catch can cause the machine to stop mid-cycle and beep if it fails to keep the door shut. In other words, this part isn’t catching onto the door latch correctly, so the door isn’t shut during the wash cycle.

That can happen for several reasons. For example, the door catch could be dirty with food stains and grease buildup. Besides, it could have suffered damage that caused it to become misaligned.

Lastly, check to see if the dishwasher racks are fully pushed in. They could be sticking out, preventing the door from closing fully. As a result, the door latch and catch don’t come into complete contact as they should.

How to solve it: Firstly, check that your dishwasher racks are pushed all the way in. That will ensure that the door can be fully closed.

Then, inspect the door catch to ensure it’s free from any damage or stains. Stains can be cleaned quickly, but you will likely have to replace a damaged door catch.

Faulty Main Control Board

About this: Your LG dishwasher’s brain is the main control board. It’s a printed circuit board which controls the dishwasher’s many components.

What’s happening: Although least likely, your dishwasher may be stopping and beeping mid-cycle because the main control board has become faulty. That typically occurs due to an electrical fault like a power surge or short circuit.

A faulty main control board can cause your dishwasher to behave erratically. That includes failing to complete an entire cycle and beeping for no apparent reason.

You can confirm that the main control board is faulty by inspecting it closely. For example, you might see or smell burns on the board. A multimeter will also show that the board’s components have no electrical continuity, even though they should.

How to solve it: Unfortunately, the main control board cannot be repaired once it suffers any fault or damage. So, you’ll have to purchase a new one.

A replacement main control board can be pretty pricey. That’s why you should only consider it last in your troubleshooting process and double-check to be sure it’s no longer working correctly.
