How to Fix the LG Washer IE Code Issue: Experienced Appliance Technician Advises

Let’s get real:

An LG Washer flashing the IE code can turn a smooth laundry day into a frustrating ordeal. Been there, done that—more times than I can count in my years as an appliance technician.

Listen up:

I’ve wrestled with this specific IE code on LG washers for various clients. And yes, I’ve cracked the code—pun intended.

So, are you ready to make that annoying IE code a thing of the past? Let’s get to it.

LG Washer IE Code

What Does the LG Washer’s IE Error Code Mean?

When your LG washer flashes that dreaded IE code, it’s telling you it can’t fill with water. The culprits? Usually, it’s your water supply, hoses, or inlet filter screen. But don’t forget, a faulty inlet valve or pressure switch can also be to blame.

So, here’s the deal:

I’ve teamed up with Dave Benson, a seasoned appliance technician from Winnipeg, to give you a bulletproof guide to kick this IE code to the curb.

Grab your toolbox. It’s game time.

7 Common Causes & Solutions

RepairableNo – once damaged, the faucets must be replaced


If your water faucets aren’t fully open, your washer will struggle to fill up and flash that dreaded IE code.

Identification and Solution:

Just last week, Jenna from our online community pinged me. Her LG WT1101CW was showing this exact code. And the tub? It was filling slower than a snail on a joyride.

So here’s what I did:

I made a beeline for those water faucets. Turned out, they were half-open. Half-open faucets are basically an invitation for that IE code to show up.

I cranked those faucets wide open and voila! No more IE code.

Dave chimes in: “Nine times out of ten, people panic and call me in to fix an IE error without first checking the obvious: Are the faucets open? Save yourself some time and a service call fee. Check those faucets first”.

So, before you dive into a parts catalog or hit the speed dial for your local technician, make sure those faucets are open, will you?

2. Kinked Water Supply Hoses

Alright, faucets checked. Still got that IE error, huh? Time to move down the line—literally.

Here’s the deal:

Your washer needs a smooth flow of water to work right. Kinked hoses? That’s like putting a speed bump in a racetrack. You’re just asking for that IE error.


Dave’s been in the game a long time. He’ll tell you the same thing I will: “Check those hoses at the back. One’s for hot water, the other’s for cold”.

Real quick:

Last month, I had a call from Sarah. Her washer had that same IE code. I pull out the machine, and what do I find? A hose twisted like a pretzel.

Dave puts it this way: “Before you spend a cent on repairs, do a hose check. A kink can mess up the whole operation.”


So, here’s your fix:

Straighten out those hoses. Get that water flowing nice and easy, and you can kiss that IE code goodbye.

Dave agrees: “A straight hose is a happy hose, and a happy hose means no more IE errors. It’s that simple”.

3. Using Floodsafe Hoses

RepairableNo – floodsafe hoses shouldn’t be used on your LG washer


You’d think floodsafe hoses are your LG washer’s best buddy, right? They’ve got this neat shut-off feature to prevent Noah’s Ark 2.0 in your laundry room.

But here’s the kicker:

Your LG washer might not be a fan. These hoses can sometimes choke the water flow, prompting that IE error.


Just last month, Jeffrey from our community had a mini Niagara Falls behind his LG WM2455HG washer. Why? His cold water hose decided to play the fountain.

His solution?

Switch to flood safe hoses. Seemed smart, until his washer started flashing the IE signal.

My point?

If you’ve hooked up flood-safe hoses to your LG washer, they might just be the culprits behind that relentless IE alarm.


Do flood-safe hoses? Here’s your game plan: swap ’em out.

Dave offers a pro tip: “Before diving in, remember – power off, water off. It’s Appliance Repair 101.”

Grab that adjustable wrench, and let’s tackle this:

  • Step 1: Detach the old hoses from the faucet.
  • Step 2: Unhook the other end from the washer’s rear.
  • Step 3: Transfer the rubber seals from the old hoses to the shiny new ones.
  • Step 4: Connect one end to the faucet.
  • Step 5: Attach the other end to your washer.
  • Step 6: Tighten those hoses. But ease up on the muscle – too tight and you might have another issue on hand.

Finally, do a test run:

Water on, power on. Keep an eye out for any leaks. If all’s dry, you’ve cracked the code!

4. Clogged Water Inlet Filter Screen

RepairableYes – if clogged but not damaged


Listen, your water isn’t as clean as you think. Tiny particles can wreak havoc on your washer. That’s why we have inlet filter screens.

And guess what?

These screens get clogged. When they do, your washer throws a fit—cue the dreaded IE error code.


First things first, inspect those filter screens.

Dave weighs in: “Head to the back of your washer. Disconnect the hot and cold hoses. Pull out those filters. You’re looking for debris, grit—anything that shouldn’t be there”.


Just last month, a Reddit user vented about this exact issue on his LG WT7150C. He had done everything right—open water supply, correct hoses. Still, he got the IE code.

Then came the lightbulb moment.

He cleaned the inlet filter screens, and boom—problem solved.

So, let’s get to work:

  • Unplug your washer. Turn off the water.
  • Disconnect the hot and cold hoses.


  • Step 1: Grab pliers and yank those filter screens out.
  • Step 2: Use a soft brush to get rid of any gunk.
  • Step 3: Rinse the screens until they’re spotless.
  • Last thing:

Put everything back where it belongs. Fire up your washer. No more IE error.

5. Misplaced Drain Hose

RepairableYes – provided the hose is not punctured or damaged


The drain hose helps your washer drain the water in the tub after it completes a cycle. Usually, it’s the first suspect when your LG washer is not draining.

Here’s the kicker:

It’s all about how deep you stick that hose into the standpipe or drain.


Last month, Greg from our Facebook group was frazzled. His LG WM2077CW was mocking him with that IE error. He’d done all the basics: checked the inlet hoses, even cleaned the filter screens. Still no luck.

So, I asked him a simple question: “How deep is your drain hose in that standpipe?”

Turns out, he’d jammed it in nine inches deep. Bingo. There was our culprit.

Get this:

Stick more than four inches of that hose into your drain or standpipe, and you’re asking for trouble. Why? Because the water gets siphoned off, messing with the machine’s ability to fill up.

Washer Drain Hose 4 Inches


Dave lays it out: “Just pull that hose back so it’s only four inches deep in the drain. That’s all it takes”.

That’s right. Four inches. No more, no less. It’s that simple.

6. Faulty Water Inlet Valve

IE code is a red flag your washer’s water inlet valve might be shot.

Here’s the scoop:

If this valve messes up, either mechanically or electrically, it chokes the water supply. Hence, “IE” blinks on your screen.


How to spot a dying water inlet valve? Easy. Your washer overflows, or maybe it’s shy and doesn’t fill at all. Listen, if your water’s full of minerals, that valve’s living on borrowed time.

Case in point:

I remember the Reddit guy complaining about constant IE errors on his LG washer. He had to clean filters and reboot his machine like it was some sort of ancient computer. Dave read the post and nodded, “Yup, classic faulty valve.”

The proof:

To be certain, grab a multimeter. Cut off your washer’s power and water, and then yank that suspect valve.

Follow the steps below to test it:

  • Step 1: Take off the rear control panel screws.
  • Step 2: Slide out the control housing.
  • Step 3: Detach hoses from the back.
  • Step 4: Unplug the valve’s wire connectors.
  • Step 5: Remove hoses from the valve.
  • Step 6: Unscrew the valve from the washer.
  • Step 7: Take out the valve.
  • Step 8: Set your multimeter to low ohms.
  • Step 9: Test those valve terminals.

Here’s the kicker:

A good valve reads between 500 and 1500 ohms.


If the reading’s lower, or there’s no continuity, that valve’s toast. Replace it.

To install a new valve:

  • Step 10: Slide the new valve into the dispenser assembly.
  • Step 11: Bolt it in place.
  • Step 12: Reattach hoses.
  • Step 13: Hook up the wires.
  • Step 14: Resecure the control panel.
  • Step 15: Reconnect the water hoses.

Last step:

Fire up your washer for a test run. If all’s good, you’ve slayed the IE code.

7. Broken Pressure Switch

RepairableNo – once faulty, it must be replaced


The pressure switch in your washer is vital for regulating water flow. If your washer flashes the IE error, the pressure switch could malfunction, especially if you’ve already ruled out issues with the water inlet valve.

Consider this:

After confirming the water inlet valve’s ohms range between 500 to 1500, it’s prudent to inspect the pressure switch.

Recently, I encountered a Reddit post highlighting a similar situation. The user identified the pressure switch as the root cause of their IE error.


There are two primary indications of a malfunctioning pressure switch – your washer struggling to fill or the machine unexpectedly overflowing.

Dave’s insight is crucial here: “To ascertain the condition of the switch, use a multimeter”.

First things first: ensure safety by unplugging the washer and turning off the water.

To access the switch:

  • Step 1: Disconnect the hot and cold water hoses at the back.
  • Step 2: Detach the rear control panel by removing its screws.
  • Step 3: Carefully lift and set aside the control panel.
  • Step 4: Remove the rear access panel, being cautious of sharp edges.
  • Step 5: Detach the hose clamp linked to the pressure switch.
  • Step 6: Disconnect the wire connector.
  • Step 7: Remove the malfunctioning pressure switch.

For testing:

  • Step 8: Prep your multimeter to a low resistance setting.
  • Step 9: Conduct a continuity test on the switch while blowing air into its hose.

The result should be clear:

If the switch shows no continuity either before or after the air is blown, it’s faulty and requires replacement.


Proceed with the replacement:

  • Step 10: Transfer the clamp from the old switch to the new one.
  • Step 11: Secure the new switch.
  • Step 12: Connect the hose to the tub.


Restore power and run a cycle to validate the efficiency of the new pressure switch. If done correctly, the persistent IE error should be resolved.

Most Affected Models

Although most LG washers would display the IE error code from time to time, some models display this code more frequently than others. Let’s explore them.
