LG Washer Vibration Sensor Replacement: Fixing the uE Error

Quick Answer

If your LG washer won't spin and keeps showing a uE code even when empty, the vibration sensor is likely faulty. You should first check the wiring harness on top of the tub for loose connections before replacing the sensor itself.

I've seen guys get quoted $600 for a new control board when all it was was this little sensor. When the vibration sensor dies, your washer basically loses its balance detector and refuses to spin to protect itself. Ignore it long enough and you're pulling soaking wet clothes out every single load. Fix it now and you're looking at a $50 part and a couple hours of your Saturday.

What Does the VIBRATION-FAULT Code Mean?

So here's the deal. This repair usually runs $40-70 in parts and it's honestly one of the better DIY fixes on an LG front-loader. These sensors don't last forever. After 5-7 years of regular use, especially in a humid laundry room, the MEMS sensor just gives out. Way cheaper than buying a new washer, and honestly not that hard to get to if you've got basic tool skills.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Internal failure of the MEMS vibration sensor55%

Worn out tub suspension shocks20%

Corroded or loose wiring harness connectors15%

Main control board fault10%

Symptoms You May Notice

The uE or UE code keeps coming back no matter how many times you stop the cycle and redistribute the load.
Your cycle gets completely stuck at the spin portion, the drum barely moves, and then the machine just gives up and stops.
Clothes coming out soaking wet at the end, like you could wring a full cup of water out of a t-shirt that should be damp at worst.
The washer starts spinning up but immediately slows back down like it hit an invisible speed limiter, over and over.
Excessive shaking at the very start of spin even with a light, well-balanced load that would never cause a problem on a healthy machine.

Can you reset a Lg washer to clear the VIBRATION-FAULT code?

Unplug the washer and wait a full 60 seconds, don't rush it. While it's unplugged, hold the Start/Pause button down for about 5 seconds to bleed off any residual charge sitting in the board. Plug it back in and run a Rinse and Spin cycle with a small load. The new sensor needs a cycle or two to calibrate, so don't panic if the first spin feels a little tentative or slow to ramp up.

Service / Diagnostic Mode

With the washer on, press and hold 'Spin Speed' and 'Soil Level' simultaneously, then press 'Power'. Press 'Start/Pause' repeatedly to cycle through component tests.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

ComponentComponent Under Test

Expected Range5–12 VDC

ConditionIf Open (OL) or infinite, replace component.

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Can I bypass the LG washer vibration sensor?

Honestly, no, and you don't want to try. The control board looks for a specific signal from that sensor before it'll authorize high-speed spin. Without it, the board just refuses to go fast. Some people have tried cutting the sensor out of the circuit, but then you either get a washer that never spins past 400 RPM or one that shakes itself off the pad with no governor on it. It's a $50 part. Just replace it.

Why does my LG washer say uE when it's empty?

When your LG throws uE on an empty drum, that's almost always the sensor going bad. A properly balanced, empty tub should never trigger an unbalance code. What's happening is the sensor is sending bad data, basically telling the board 'hey it's shaking really bad in here' when the drum is sitting perfectly still. Sometimes it's corrosion on the connector, sometimes the sensor itself is toast. Start with the wiring check in step 3 before you order anything.

Is the vibration sensor the same as the Hall sensor?

Two totally different parts. The Hall sensor, LG calls it the RPS sensor, sits on the motor at the bottom rear of the machine and tracks motor rotation speed and position. The vibration sensor is up top on the outer tub and measures physical shaking. One's about motor speed, one's about balance. They fail for different reasons and they're definitely not interchangeable. Make sure you're ordering the right one or you'll be returning a part.

How much does it cost to have a pro replace the vibration sensor?

Most shops are going to charge you $150-250 all in. That's typically a $75-100 service call, an hour of labor, and the part. Doing it yourself you're looking at maybe $45 for the sensor and two hours of your Saturday. If you've got basic tool skills and you're not afraid to pull a panel off, this is genuinely one of the better DIY repairs on an LG washer.

How long does this repair take?

For someone who's done it once, 45 minutes start to finish. First time? Budget 90 minutes to 2 hours. Most of that time is just getting comfortable finding stuff and not rushing the wire connector. The actual sensor swap is fast once you've got the top off. Don't rush the wiring harness clip. That's the part people break and then they're waiting on another part.

What's the part number for the LG vibration sensor?

The most common ones are EBG61106803 and EBG61106804, but it depends on your exact model year because LG changed the design a few times. Pull your model number off the sticker on the door jamb, not the back of the machine, and cross-reference it on the LG parts site or Repair Clinic. Don't just order by model series. I've seen people get the wrong one that way and it's a waste of time.
