LG is known for its innovation, top quality, and stylish products. For example, their dishwasher lineup is a popular choice among consumers. LG makes great dishwashers, but they also tend to have a few common problems here and there. The LG dishwasher Keeps Turning Off is a common issue that’s luckily rather easy to diagnose and fix.
LG dishwashers have a number of different electrical issues that can result in the machine turning off before finishing a load. The problem may be related to the power supply, water getting into the control panel or an electrical overload — but it’s almost certainly user error. Don’t start and stop cycles manually to clear them out: let the dishwasher run through its regular cycle without any changes, as doing so can cause additional problems.
Don’t you hate when your dishwasher stops mid-cycle and you have to start the process all over again? No matter how many times you call, the repairman comes, and he still doesn’t fix it.
LG Dishwasher Keeps Turning Off – Troubleshoot And Diagnosis
LG dishwashers are set to start automatically when power is restored following a power outage. This means that a machine that keeps turning off may be experiencing a reoccurring and random power supply issue, such as an electrical spike, or it may be linked to one of the other possible causes below:
1. Check The Door Latch
The door latch is responsible for keeping the door closed during the dishwashing cycle. If the door latch is not functioning properly, the dishwasher will turn off automatically.
There are a few things you can do to troubleshoot this issue:
- First, make sure that the door is properly latched. If the latch is not engaged, the dishwasher will turn off.
- Second, check the strike plate on the door. If the strike plate is damaged or misaligned, it can prevent the door from latching properly.
- Third, inspect the door seal for any cracks or damage. A damaged door seal can also cause the dishwasher to turn off.
If you have tried these troubleshooting steps and your LG dishwasher still keeps turning off, you may need to replace the door latch assembly. This is a relatively simple repair that can be done yourself with a few tools.
2. Start Button Issue
The LG dishwasher has a very simple and effective start button — press once to begin your desired cycle. After setting everything up, pressing the start button is the last thing you must do to complete your wash.
The LG dishwasher will turn off after starting if the Start button is held instead of pressed.
If you want your new clothes and bedding to be washed, you should quickly press the button and then release it.
One downside to this machine is that, if you hold that button for longer than a few seconds, it’ll end the current wash cycle. But in general, when you’re done using it, the machine will run for a couple minutes and then stop automatically.
To you, it’ll seem as if the machine started on its own, before stopping all on its own.
The LG dishwasher’s Start button can save you a bunch of time and help ensure a successful wash cycle. You may think that pressing the Start button once will start your dishwasher’s cycle — but, it won’t!
Holding that button for too long will kick off other features within the machine like TurboWash or stopping the dishwasher.
Fortunately, you can tap into these benefits by simply pressing and releasing on the Start button quickly.
3. Blown Thermal Fuse
The thermal fuse is a safety device that cuts power to the dishwasher if it gets too hot.
If your dishwasher’s thermal fuse has blown, you’ll need to replace it before the dishwasher will work again.
If the dishwasher overheats, the thermal fuse will blow and the dishwasher will turn off. The most common cause of the dishwasher overheating is a clogged vent. The vent allows air to flow into the dishwasher and cools the motor. If the vent is blocked, the air can not circulate and the dishwasher will overheat. Another common cause of the dishwasher overheating is a failing heating element. The heating element heats the water in the dishwasher and if it fails, the water will not be heated properly. This can also cause the dishwasher to overheat.
Thermal fuses are found in the control panel of most dishwashers. To access the control panel, first remove the screws that hold the panel in place. With the screws removed, you should be able to lift the panel off of the dishwasher.
Once you have access to the control panel, locate the thermal fuse. The fuse will be mounted on a small circuit board and will likely be labeled “T” or “Thermal Fuse.” Using a multimeter, check to see if the fuse is blown. If it is, replace it with a new one of the same type and rating.
With the new fuse in place, reattach the control panel and screw it into place.
Turn on the dishwasher and check to see if it works properly. If it does, then you’re all set! If not, there may be another issue causing your dishwasher to turn off.
3. Power Supply Issue
If you have an LG dishwasher that keeps turning off, it’s likely due to an unstable power supply. This can be caused by a number of things, including a weak electrical connection, a damaged power cord, or a tripped circuit breaker.
To fix this problem, start by checking the electrical connection to the dishwasher. Make sure the cord is firmly plugged into the outlet and that the outlet itself is not loose. If the cord is damaged, you’ll need to replace it.
Power supply disruptions are a common problem in homes, and they can easily affect even the most reliable of appliances. LG dishwashers may be affected by power interruption issues, which can cause sudden shutdowns and unexpected silence when washing. To keep your machine operating as you want it to, make sure that you always have a backup power source at home.
If the electrical connection seems tight and secure, check your circuit breaker. If it has tripped, simply reset it and see if that fixes the problem. If not, you may need to call an electrician to investigate further.
4. Water Getting Into The Dishwasher Control Panel
The control panel isn’t meant to be taken for granted — it’s your gateway to the dishwasher! The aforementioned buttons transmit information and directives from you, the user, to the dishwasher all day long.
They tell it when to start a wash cycle and how hot or cold you want that water to be. And they also let you know exactly how much time is left on said cycle while simultaneously providing an indication as to where that cycle currently stands in total progress.
There’s been a known issue with LG dishwashers. Several models have experienced moisture infiltration problems, due to issues with the moisture barrier inside the machine. That means water can get into the control panel and affect parts inside.
LG dishwashers with faulty control panels may stop working or turn off suddenly, even when the buttons weren’t pressed by users.
LG recently announced that several of their dishwasher models have been affected by water seeping into the control panel. That water has caused components to rust over time, leading to lagging performance and scratches on the stainless steel tub.
Thankfully, LG are offering customers with affected machines a replacement part for their existing dishwashers. With a new controller installed, you can continue using your dishwasher without any problems. The process is fairly simple: first, contact LG customer service to receive your replacement part from the retailer you purchased the unit from.
5. Electrical Circuit Is Overloaded
Though dishwashers are useful appliances, they’re also power-hungry and use a lot of electricity. That’s because the appliance typically draws plenty of power when operating to power both the water valves and pumps inside, as well as the heating element that heats up the water.
When the dishwasher is in use, there should be plenty of juice. This means that you need to install a dedicated power circuit for it. That way, it doesn’t get tripped up by other things like a hair dryer or an oven being used at the same time and causing a power overload problem.
You need to investigate whether or not your dishwasher is sharing a circuit with other appliances. Basically, it needs to be on its own circuit so that it can work at peak performance without having the risk of tripping the circuit breaker.
When your dishwasher stops drying, your first step should be a quick check of the circuit. This will ensure that it’s not just your dishwasher shutting down because other appliances are drawing too much energy from it.
After tracing the electrical circuit, you can troubleshoot poor cycle performance by reviewing whether or not the wiring connections are tight and both the inlet water valve and outlet water valve are open.
Before you relocate your dishwasher, check whether it’s already connected to a dedicated circuit. That means no other appliances draw power from the same supply, so there’s always enough juice for your appliance — and nothing that could cause it to stop working.
But not all homes come with a dedicated circuit, so you may have to consult a qualified electrician who can advise on any work that needs done to install one.
6. Motor Or Pump Issue
If your dishwasher is shutting off mid-cycle, it’s likely due to an issue with the motor or pump. Both of these components are essential for keeping the dishwasher running, so if one isn’t working properly, the whole cycle will be interrupted.
There are a few things you can do to try and troubleshoot the problem yourself.
First, check to make sure that there is nothing blocking the path of the motor or pump. If there is something stuck in there, it could be causing the dishwasher to turn off.
Next, take a look at the motor itself. If it seems like it’s not getting power, you may need to replace it. However, if the motor looks fine but the dishwasher still won’t run, the problem is likely with the pump.
To check the pump, first make sure that there is no water leaking into it. If there is water leaking, that could be causing the pump to overheat and shut down. Once you’ve ruled out a leak, try running the dishwasher without any water in it. If the pump still doesn’t work, you’ll need to replace it.
7. Vent And Fan Problem
If your LG dishwasher keeps turning off, it’s likely due to a vent or fan issue. The most common cause of this problem is a clogged vent. A clogged vent can cause the dishwasher to overheat and turn off. Another possible cause is a faulty fan. A faulty fan can also cause the dishwasher to overheat and turn off. If you’re having this problem, we recommend checking the vent and fan for any problems.
After reading this article, you should now be aware of some of the reasons why your LG dishwasher may keep turning off. While there could be a more serious issue at play, such as a faulty wiring or dishwasher model, it is more likely that a simple fix like cleaning the filters or resetting the machine can solve the problem.
If your dishwasher continues to turn off, we recommend checking these two issues first and then contacting an appliance repair technician if necessary.
