Why My LG Washing Machine Showing PE Error: Troubleshooting Guide

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?

So that 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?

To address the PE error, users can follow these detailed steps, which are supported by multiple sources:

Reset the Machine:

• Unplug the washing machine from the power outlet for approximately 1 minute. This can reset the system and clear temporary errors.
• Plug it back in and attempt to start a cycle. This step is recommended in Coolblue and Domex Ltd.

Check the Water Supply:

• Ensure the water supply valve is fully open to allow adequate water flow.
• Inspect the supply hose for kinks, blockages, or damage. Clean the filter if dirty and reconnect. This is advised in LG USA Support.

Inspect Wiring (Advanced Users):

• If you are comfortable with appliance repair, check the wiring harness connecting the water level sensor to the main control board.
• Look for loose connections, damaged wires, or signs of burning. Use a multimeter to test for continuity if possible.

Address Environmental Factors:

If the machine is installed in a humid area, disconnect the power plug, wait 5 minutes, and reconnect. This can resolve moisture-related issues, as noted in LG Jordan.
