If your LG dishwasher turns off constantly, you need to find a solution to the problem as soon as possible so it doesn't get worse. Here are what to do if your LG dishwasher continues turning off:

Check The Door Latch

The door latch is the first place to check if your dishwasher keeps turning off. Always make sure it is shut. If your door latch is broken, then your dishwasher will keep turning off. 

To get your dishwasher running again, you need to replace the latch. Replacing it is very simple as the only tool needed is a screwdriver. 

Check For Blown Fuse 

Another reason why your dishwasher keeps turning off is if you have blown a fuse. Aside from turning off, your dishwasher won't resume its cycle if there's a blown fuse. 

You can find out if you are dealing with a blown fuse by checking the control panel to see if there are any blinking lights. If the control panel is dark, it means the dishwasher is not getting any power. 

Examine The Thermal Fuse

You can also check the thermal fuse,. It can be seen at the back of the control panel. Before you disassemble your panel, ensure you have disconnected the power. 

A bad thermal fuse can cause the dishwasher to keep turning off. The thermal fuse helps to protect the dishwasher from overheating. When the thermal fuse notices that the heat is too much, it turns off automatically in order to prevent consequent motor damage. 

If the thermal fuse is blown, you will need to replace it. So you should find out whether it is blown before deciding it is the reason why your dishwasher keeps turning off.

Aside from overheating, a blown thermal fuse can also be caused by water leaks, faulty dishwasher components, and worn-out internal wiring. 

Check The Control Panel 

Without the control panel, your dishwasher cannot run its cycle. A faulty control panel will make your dishwasher short circuit.

To know that the issue is coming from the control panel you have to see blinking lights on it. If all looks normal but your dishwasher keeps turning off, then you need to reset the panel. 

Check For Tripped Fuse 

The circuit breaker of your home will trip automatically if a unit is consuming too much energy. If the dishwasher has not been shutting off before and your door is in perfect working condition, the issue might be because of a tripped fuse.

To be sure whether your dishwasher keeps turning off because of a tripped fuse, you can take a look at the indicator lights to see if they are on. Make sure to fix the fuse if it is tripped.

Inspect The Motor Or Pump 

If you have thoroughly checked all the mentioned areas and no source has been found, then you should check if your motor or pump is faulty. A dishwasher requires enough water and pressure in order to wash your dishes.

When the motor of your dishwasher is damaged, it won't produce enough water pressure, thereby causing the dishwasher to keep turning off. Faulty motors are mostly caused by issues with the circulation pump or excess build-up of soap. 

If it is not attended to, it will deteriorate over time and this may damage the seal, thereby causing water leaks. The most efficient way to solve this problem is by replacing it. 

Replace The Vent And Fan 

During the drying process, what keeps your dishwasher running at its peak is the vent and fan. They work by forcing out the hot air

When the fan does not work, there is an accumulation of air which prevents dishes from drying and causing your appliance to turn off. The recommended fix for this is a replacement.

If you can't handle fuse boxes or circuit breakers, seek the help of a professional. 

What Size Power Cord Do I Need For A Dishwasher?

The size of the power cord used for a dishwasher varies. If your dishwasher is 15 amp, you will need to get a #14 or #12 wire. But if you want to wire a dishwasher of 20 amp, you will need a wire of 12 gauge

Note that your breaker will determine the size of the wire. Most times, the circuit breaker will turn off in the case of power surge. Make sure to use a dedicated circuit of at least 20 amps when installing a dishwasher. 

Can You Pull Out A Dishwasher Without Disconnecting It?

No, you cannot pull out your dishwasher without disconnecting it. Here is how to safely remove a dishwasher:

  1. Disconnect the water supply: Detach the two pipes that connect the dishwasher to the plumbing system. 
  2. Detach the drain line: The dishwasher is also linked to the plumbing system through a drain line. Find the rubber hose and disconnect it.
  3. Loosen the mounting brackets: Usually, the dishwasher is held by some metal brackets located under the kitchen's cabinet lip. Find it and loosen it. 
  4. Unscrew the dishwasher's legs: You need to unscrew the leg of the dishwasher before you can move it out of its location, and you need to lower it as well.
  5. Pull out the dishwasher: Carefully pull the dishwasher out of the cabinet.

Does An LG Dishwasher Have To Be On Its Own Circuit?

The LG dishwasher needs to be on its own circuit, and this dedicated circuit cannot supply any other device. This circuit supplying the dishwasher should also have a circuit breaker of at least 15 amps

The reason for this is that connecting more than one electrical appliance to a circuit can lead to power overload which can cause fire or other electrical damage.

Other home appliances like garbage disposals, ovens, and refrigerators need their own circuit. Some modern kitchens have not less than seven 20-amp circuits so that potential disasters can be prevented. These circuits can accommodate all common household appliances.
