If you are reading this article, then it is likely that your LG dishwasher won’t start. Don’t worry! You are not alone, and there are a number of things you can do to troubleshoot the issue before calling for professional help. Below, we have compiled a list of tips on how to troubleshoot an LG dishwasher that won’t start.

Why LG Dishwasher Won’t Start? Troubleshoot and Diagnosis

It can be frustrating when your LG dishwasher is not starting, and you are left with dirty dishes. Not to worry, there are a number of reasons that this can happen, and below we will list the most common LG dishwasher problems.

LG Dishwasher Won't Start

Below you will find possible solutions for LG dishwashers that don’t work. Take your time as they require patience and persistence if you want them to be successful. If these tips do not work, it might be time to call a professional.

Dishwasher Not Getting Power

If the LG Dishwasher won’t start, you can check to see if there is an electrical connection by unplugging and then plugging in the dishwasher. If it does not start up after doing this, try flipping over a nearby circuit breaker or resetting your home’s main fuse.

Make sure your dishwasher is plugged in: Check the power cord that goes from your dishwasher to the outlet.

If there is a break in it, you will need to replace it or repair it. If you have an extension cord plugged into another plug and then on top of that has another wire going from this extension cord to your dishwasher, make sure nothing else was using electricity at the time when it stopped working. 

This could mean unplugging everything before checking for other problems with your LG Dishwashers! Do not forget about outside sources such as lightning or even electrical surges protecting against storms! You do want to consider all possibilities if they are possible causes of LG dishwasher issues.

Dishwasher breaker tripped: If the breaker trips, you will need to reset it. This is usually a quick fix that can only take up to 15 minutes to complete. There are two ways of fixing it when this happens- by turning off and then back on or simply flipping the switch for the appropriate breaker in your electrical panel.

Blown Thermal Fuse: A thermal fuse acts as a circuit breaker to protect the dishwasher from overheating. If your LG Dishwasher is not functioning normally and has blown its thermal fuse, you can replace it with one of these two methods: reconnecting wires and clipping leads or installing new fuses.

Check Door Latches and Switches

If your dishwasher doesn’t start, you may need to replace the door latch or the switch for the door latch. The door latch assembly is designed to hold the door closed during a cycle. It also houses switches that provide electricity to controls inside the dishwasher. If the door cannot close, or if the switches are defective, then your dishwasher will not start. Inspect the latch assembly for function and damage.

A broken latch assembly can also prevent your machine from starting. Inspect for damage or loose connections in the switch mechanism at the top of your dishwasher.

Locate the door switch at the top of the dishwasher and make sure that it is activated when you close the machine. A continuity test with a multimeter will also work, but be sure your power to the dishwasher is turned off first.

Child Lock is ON

There are many different features that dishwasher brands can offer. One of the most helpful is a child lock feature to prevent little ones from accidentally starting the machine while they’re exploring and playing in your kitchen! If you are not sure how to Turn OFF the child lock, you can check the owner’s manual for the solution.

To Turn OFF the child lock on the LG dishwasher, press and hold the child lock button for a second or two.

A dash will appear on the display screen, confirming that the child lock is now OFF.

Check Selector Switch

A dishwasher selector switch is usually used to select the particular settings for a wash cycle, such as heated dry and heated wash cycles. The dishwasher may not work properly if the switch is defective or if you fail to press down on the buttons fully.

Make sure you press the switch down and use a multimeter to double-check if it’s working. The contacts of the selector switch should be checked for continuity with a schematic guide in mind.

If the selector switch on the control panel is stuck between settings, unstick it and then push the “start” button. If more than one button is pressed at the same time, this will create a no continuity situation for your switch and bring no power to these controls.

Incorrect Dishwasher Cycle Settings

If your dishwasher does not start, first check to make sure the appropriate cycle setting is selected. If you have accidentally selected a wash and dry or heated-dry cycle in place of a regular cycling option, this may be your problem.

Do your dishwasher’s lights seem to be on but not flashing? Does the timer seem to show that it is running, but nothing seems to be happening on the machine? Maybe your machine has entered “Hang Mode.” If the dishwasher becomes stuck and won’t start a new cycle, it can be fixed by turning off power to the machine completely. From there, pressing the reset button for the required time and then starting the machine again should fix it.

The following LG dishwasher functions can cause a dishwasher not to start:

  • Delay Start (DELAY): If you have enabled Delay Start, the dishwasher will not start until that time has elapsed.
  • Delay Wash (DLY): If you have selected a pre-scheduled cycle using this option, it will be delayed by the amount of time specified from when water starts flowing or if the delay feature is already on.
  • Time Dry (DRY): If you have selected a pre-scheduled cycle using this option, the dishwasher will dry dishes.
  • Delay Wash/Time Dry (DLY+DRY): Dishwasher with delay wash and time the dry function is programmed to start the sequence for washing after the specified number of hours has elapsed from when water starts flowing or if delay feature is already on.
  • Control Lock: The control lock prevents accidental activation of the dishwasher.
  • Low Rinse Aid: You have selected a pre-scheduled cycle using this option, and it will not start until the rinse aid is low enough to trigger the sensor.

Check Water Supply

If you are not sure if the water supply is working, turn off and unplug the dishwasher. Check both hot and cold water supplies for leaks. If there are no leaks on the dishwasher inside, check that all connections to the faucet or house piping below the sink are tight.

Make sure that the water valves are turned on, and check the hose for any kinks or ruptures. Straightening a hose will work, but it needs to be changed if there is a leak in the hose.

If your dishwasher won’t start, it may be because the water inlet valve is faulty. If this part does not work correctly during wash cycles, only some of your dishes will be cleaned properly. We recommend seeing a professional about getting repairs or replacing the defective component as soon as possible!

Defective Timer

The timer may be defective if the Dishwasher is not completing one or more wash cycles. Resetting a timer will work, but it needs to be replaced if there are any other problems with the device.

The timer on your Dishwasher keeps track of how long each cycle should last so as to provide optimum cleaning without wasting electricity through overuse; however, like many other appliances, timers are often misdiagnosed – make sure before replacing any parts always check for signs such as faulty wiring or low voltage supply.

Faulty Drive Motor

If your dishwasher doesn’t start at all, it may be because the motor inside has malfunctioned in some way. One of the most common causes for this problem is a faulty drive motive, as these motors often use up and wear out over time or are damaged by water.

A dishwasher’s drive motor is responsible for circulating the water to clean all of your dirty dishes. The power comes from a timer or electronic control in conjunction with a start relay. If your dishwasher won’t start after the start relay sends power to the motor, it may be because you have a defective drive motor. You might also hear loud humming sounds coming from it – this could mean that there’s something wrong with your current one and should be replaced for optimal performance.
