11 Reasons Why LG Dishwasher Not Turning On [Solution]

If the dishwasher is not turning on first, you should identify the issue causing this problem.

This section will look into different issues that can escalate the dishwasher not turning on the problem in LG dishwasher. Here is the list of issues you can check on your LG dishwasher.

Power supply issue

The power supply issue is the first and foremost thing that I recommend you check on your dishwasher.

If your dishwasher is not starting, there must be a power supply or electrical problem on your dishwasher.

A dishwasher requires a stable power supply in order to operate smoothly; therefore, make sure that you are receiving stable voltage. 


If you have checked the voltage and there is no issue. I recommend you check the dishwasher power cord to see if it is properly functioning or not.

Sometimes the dishwasher power cord can be torn up, which can create a power supply issue in the dishwasher.

If you have used an extension cord, make sure it is properly plugged. You should replace the power cord with a new one if it is damaged. 

Besides this, I also recommend checking the power switch where you plug the dishwasher cable. Check if it is passing current or not.

You can test it using a mobile phone charger or any electronics accessories. If the power switch is working fine, there must be an internal electrical issue with your dishwasher. 

Damaged door latch and switches

If there is no problem with the dishwasher power supply, you should check the dishwasher door latch.

A damaged door latch can stop the dishwasher from running. The dishwasher door latch is equipped with special types of sensors that prevent the dishwasher from starting the cycle when the dishwasher door is open.

In this case, you can start the cycle, and all you see is an error code in your dishwasher. 


If your dishwasher door latch is damaged, you can’t lock the dishwasher door. You should replace it with a new latch or switch.

Otherwise, you can’t start the cycle on your dishwasher. Here is the step-wise instruction to inspect dishwasher latch assembly. 

  1. Turn off the dishwasher power supply. 
  2. Open the dishwasher door and locate the latch. It must be secure inside the metal panel. 
  3. Remove the screw securing the door latch on your LG dishwasher.
  4. Once you remove the door latch, you can now see the dishwasher switch just beside the door latch. 
  5. Remove the wire connected to the switch and remove the switch from the dishwasher. 
  6. Now turn on the multimeter and test the switch using two positive and negative probes. If the switch is working fine, you will see a reading in your multimeter. 
  7. If the multimeter does not show any kind of reading, you need to replace your dishwasher door switch. 

This is how you can test the LG dishwasher door switch. If you want to replace the dishwasher door latch, you should remove the screw securing the dishwasher door latch.

Once you have to remove the door latch, remove the wire connected to the door latch and remove the door latch from the dishwasher. Now place a new door latch and connect the latch to the switch. 

Child lock mode is ON

LG dishwasher comes with tons of features that make it different from other dishwashers. However, if you don’t know to use these features, it can become trouble.

Child lock is a mode that disables all the functioning of the dishwasher when it is turned on. 

If you have children in your home, this mode can save your dishwasher from your child. If this mode is turned on, you can’t start your dishwasher.

Therefore, I recommend you to check if this mode is activated on your dishwasher or not. 


If child lock mode is turned on, you can’t start the wash cycle or literally any functioning of your dishwasher.

First, you need to turn off child lock mode; then, you can’t start the wash cycle on your dishwasher. If you don’t know how to Turn Off child lock mode, don’t worry. 

You can find this information in the dishwasher manual. If you don’t have child lock mode, don’t worry;

there must be a child lock button on your dishwasher. Press that button and hold for two seconds it will turn off child lock mode on your dishwasher. 

Setting issues

If you have played with a dishwasher setting, it can also prevent the user from starting or turning on the dishwasher.

As mentioned earlier, there are various types of setting for each of the features in the dishwasher.

If you have used any of these settings while configuring, recheck the dishwasher setting and undo whatever you have changed. 


If you don’t have any idea what you have done with dishwasher settings, don’t worry. There are mainly four settings that can prevent the dishwasher from turning on. Here is the list of settings. 

Delay start (Delay)

This function in the LG dishwasher lets you start your dishwasher at a certain time.

As the name mentioned itself, these features start the dishwasher at a specified time set by the user.

If you have a bit more time, you will need to wait to run the cycle in the dishwasher.

Delay Wash (DLY)

Delay wash is another setting that prevents the dishwasher from starting a wash cycle. If you have selected a pre-scheduled cycle in this mode, you will have to wait sometime to start the wash cycle. 

Control lock

The control lock function in the LG dishwasher prevents the dishwasher from accidental activation. There is some condition under which this function automatically gets activated.

If activated in your dishwasher, Turn off the Control Lock, then try to start the dishwasher.

Low rinse aid

Low rinse aid is also similar to a delayed wash cycle. If you have selected a pre-scheduled cycle, your dishwasher won’t start until the rinse aid is low. 

Water supply 

Water is very important in the dishwasher if your dishwasher doesn’t have enough water. You can’t start the wash cycle on your dishwasher.

I recommend you to check the water supply pipe and see if the water is properly flowing inside the dishwasher or not.

Besides this, check the incoming water pipe to see if there is a presence of mineral or clogged builds. A faulty water inlet valve can also prevent the dishwasher from turning on. 


The solution to this problem is to check for minerals build up inside the pipe and clean the mineral or clog build if necessary.

If this doesn’t fix your problem, the water inlet valve must be an issue. The water inlet valve plays an important role in the dishwasher. 

It prevents over flooding in the dishwasher. When the water reaches a certain level, it stops loading water inside dishwasher tanks.

If it is faulty, it could stop loading water inside the dishwasher and stop you from starting the cycle. 

Defective timer

The main function of the dishwasher timer is to control the cycle length. Sometimes the timer can get faulty, which can prevent you from starting a new cycle.

In most case, resetting the dishwasher fix this issue. However, if resetting doesn’t work, you should replace the existing dishwasher timer with a new timer.

This would help you start your LG dishwasher without any problem if there was a defect on a timer.   

Faulty Motor

A faulty motor could also stop the functioning of the dishwasher. The motor plays an important role in the dishwasher as it circulates water all around the dishwasher.

If the motor is not working in the dishwasher it can’t load and drain water from the dishwasher.

The dishwasher motor is located at the bottom of the dishwasher you can check by removing the bottom access panel of the dishwasher.

Should I call LG customer support?

If the above-discussed method didn’t work on your dishwasher, then there must be a technical problem with your dishwasher.

In this case, I recommend you to contact dishwasher technicians or LG Customer support. 

You should contact LG customer support if you have a valid warranty period. They will guide you to fix almost any problem in the dishwasher.

You can check the warranty period from the warranty card you got while buying a dishwasher.
