Alright, so you’re just about to do your laundry when, BAM—your LG top load washer decides to showcase the dreaded “PE error code” on its display.

Washing machine errors are the absolute worst, right? This particular error is all about the water level sensor acting up.

Whether it’s faulty electronics or just a dirty sensor, it needs sorting out. 

Not quite sure what to do? Don’t worry, I’ve got your back! From simple repairs like cleaning the sensor or checking the plug, to knowing when to contact a technician, we’ll get your appliance up and running in no time. 

What Is a PE Error on an LG Washing Machine?

When my LG washing machine shows a PE error, it means there’s a problem with the water level sensor. This sensor checks the water level during the wash. If it’s broken or the wires connecting it to the control board are damaged, you’ll see the PE error code on the display.

Can You Continue Using the Washing Machine with a PE Error?

just so you know, it’s usually not a good idea to keep using your washing machine if you’re getting a PE error. That PE error on an LG washer means there’s something wrong with the water level sensor. This can mess up the water levels during washing.

What Causes the PE Error on an LG Washing Machine?

1. Power Supply Issues

Power supply issues with LG top-load washers can be a real headache.

Here’s what you can do to troubleshoot and hopefully fix the problem:

  1. Check the Power Cord: First things first, make sure the power cord is snugly plugged into both the washer and the wall outlet. Sometimes just unplugging and plugging it back in can do the trick.
  2. Test the Outlet: Grab a small appliance, like a lamp, and plug it into the same outlet. If it works, your outlet’s fine. If not, you might need to check your circuit breaker and reset it if it’s tripped.
  3. Power Outage Check: If you recently had a power outage, just restart your wash cycle once the power’s back on.
  4. Inspect the Wiring: Take a good look at the wiring connecting your washer to the outlet. If you spot any damage or wear and tear, you might need to get those wires replaced.

2. Faulty Pressure Sensor

I’ve found that a faulty pressure sensor often causes that annoying PE error on LG washing machines.

This sensor’s job is to detect the water level in the tub and send a signal to the main control board.

When it’s acting up, it messes things up by making the machine either underfill or overfill, and that’s what triggers the PE error.

3. Clogged Water Inlet Filters

Real deal on that pesky PE error you might be seeing on your LG washing machine. Now, I might sound smooth as silk, but I ain’t afraid to get a little gritty with the deets, ya dig?

Here’s the skinny – that PE error is usually caused by the water inlet filters getting all clogged up. And why’s that, you ask? Well, let me break it down for ya:

First up, we got sediment and debris – that nasty stuff from the water supply can build up in the filter, slowing down that water flow and bam! PE error city, baby.

Next, we got hard water. Now, I ain’t talking about them fancy-schmancy mineral waters you pay an arm and a leg for.

Nah, I’m talking about the mineral deposits that can cake up in that filter over time, causing them water flow issues and triggering that PE error like it’s nobody’s business.

But wait, there’s more! If you ain’t been keeping up with your maintenance game, that filter’s gonna get clogged up faster than you can say “spin cycle.” Ain’t nobody got time for that, am I right?

And let’s not forget about that low water pressure situation. If the pressure in your household pipes ain’t up to snuff, that filter’s gonna get clogged up quicker than a kid in a candy store.

Last but not least, we got them clogged water supply lines. If their lines ain’t flowing like they should, that water ain’t gonna make it to the machine, and bam! PE error, just like that.

4. Malfunctioning Control Board

That pesky PE error on your LG washer usually means the control board is acting up. Now, this could be for a few reasons, so listen up:

  1. Wiring Gone Wrong: Yo, the wires connecting that water level thingy to the main control board might be damaged, loose, or just not working right, ya feel me?
  2. Burnt-Out Bits: Some of the little components on the control board itself could be fried or faulty, making your machine act all crazy.
  3. Software Shenanigans: Sometimes the software or firmware on that control board can get glitchy or outdated, causing it to go haywire and throw that PE error.
  4. Physical Pain: If that control board took a tumble or got wet, that physical damage could mess with its ability to function properly.

How to Fix the PE Error on an LG Washing Machine?

You’re chilling and suddenly your washing machine starts flashing the PE error – super frustrating, right?

The PE error in LG washing machines is a common issue, and it usually revolves around the water level pressure sensor being on the fritz.

If the PE error is displayed on your LG washing machine, don’t panic!

First, try to reset your LG washing machine by unplugging it. This easy trick sometimes clears the error code on an LG washer.

Just disconnect the power and wait for a minute or so before plugging it back in. If the reset doesn’t do the trick, let’s dig a bit deeper.

Next, it’s time to check the wiring around the pressure switch. Make sure everything is snug and there are no loose connections.

Sometimes, the LG washing machine error code pops up because of a loose wire or two.

If you’ve ensured that everything’s tight and the PE code is still there, the error in LG washing machines often suggests that the water level pressure sensor might be malfunctioning.

Replacing this part will typically solve the problem and stop the annoying PE error in its tracks.

You can grab a new sensor from an appliance parts store or the LG site.

If you’re unsure whether you can tackle it yourself, it might be best to call a pro or use the Help Library on the LG site for some guidance.

Sometimes though, these washing machine error codes can indicate bigger issues.

If your washer is relatively new, check if the warranty still covers it. This could save you some bucks.

Meanwhile, if your laundry area is humid, the extra moisture can cause electrical issues which might also trigger the LG washing machine PE error.

Improving ventilation could be an easy fix. 

If you do end up consulting the owner’s manual, you’ll find detailed steps showing how this code indicates specific faults and how to properly address them.

Whether you’re a seasoned DIYer or someone who wants to throw their hands up and call customer service, the important thing is to stay cool-headed and methodical.

Any error code on an LG washer can be annoying, but it’s usually manageable. 


What does the PE error code indicate on my LG washing machine?

PE error code indicates an issue with the water level pressure sensor. This sensor communicates with the washing machine to ensure it fills with the correct amount of water.

How can I reset my LG washing machine to clear the PE error?

To reset your LG washing machine, unplug the washer for about 10 minutes. This will allow the system to reset. Plug it back in and see if the PE error code disappears.

What should I do if my LG washing machine keeps showing the PE error code?

First, check the wiring of the water level pressure sensor. There could be a loose wire harness or a defective pressure switch. If everything looks fine, the sensor itself might be faulty and may need replacing.

How do I inspect the water level pressure sensor for faults?

To inspect the water level pressure sensor, you will need to open the washing machine’s top panel. Look for the hose that connects the water level pressure sensor to the washer. Check for any kinks, blockages, or damage to the hose.

Can a PE error occur due to a water leak?

Yes, a water leak can affect the pressure sensor and prompt a PE error code. If you suspect a leak in your washer, inspect all hoses and connections carefully.

How can I determine if the pressure sensor needs to be replaced?

If resetting the machine and checking the wiring doesn’t resolve the issue, use a multimeter to check for continuity in the pressure sensor. If it doesn’t have continuity, the sensor is likely defective and needs a new one.

Can a blocked hose cause a PE error code on my LG washing machine?

Yes, a blockage in the hose that connects the water level pressure sensor can cause the PE error code. Inspect the hose for any obstructions that might prevent it from correctly reading the water level.

Should I contact LG support for a persistent PE error code?
