LG IE
Water Inlet Error
Low severityVerified Diagnostic Guide
SeverityLow
What Your Machine Is Actually Telling You
IE means the washer didn't detect water filling within 8 minutes. LG's pressure sensor didn't register the expected water level rise within the time limit.
LG's inlet system: Two solenoid valves (hot and cold) open when the board commands fill. Water passes through mesh filter screens at each inlet port before entering the machine.
Common causes:
1. Water taps closed (30%) — someone turned them off.
2. Inlet filter screens clogged (25%) — mineral/sediment deposits.
3. Kinked inlet hoses (15%) — hose crimped behind machine.
4. Low water pressure (10%) — house-wide issue.
5. Inlet valve failure (10%) — solenoid won't open.
6. Frozen pipes (5%) — cold installation.
7. Main board (5%) — not sending signal to valves.

What You're Probably Seeing Right Now
- IE appeared right after pressing Start.
- Drum is completely empty — no water entered.
- You can hear valve clicking but no water flow.
- Other fixtures in house have normal water pressure.
- IE started happening in cold weather.
DIY Fix — From Easiest to Hardest
1
Check Water Taps (30 seconds — Fixes 30%)
1. Find hot and cold taps behind washer.
2. Turn both fully counterclockwise (open).
3. Restart cycle.

3. Restart cycle.
2
Clean Inlet Filter Screens (10 minutes — Fixes 25%)
1. Turn off both taps.
2. Unscrew hoses from washer.
3. Find the small mesh screens in each inlet port.
4. Pull out with needle-nose pliers.
5. Rinse under running water.
6. Reinstall, reconnect hoses.
7. Turn on taps — check for leaks.
**Clean every 6 months** in hard water areas.

3
Check Hoses for Kinks (2 minutes)
1. Pull machine forward.
2. Inspect both inlet hoses.
3. Straighten any bends or kinks.
4. Replace if cracked or bulging ($15-30 pair).

Test Water Pressure (2 minutes)
1. Disconnect a hose from the washer, point into bucket.
2. Turn on that tap.
3. Strong flow (fills bucket in 10 seconds) = adequate.
4. Trickle = water supply issue.
5. LG needs minimum **14 psi (1 bar).**

5
Test the Inlet Valve (10 minutes)
If water supply is fine:
1. Unplug.
2. Access valve (back panel, top).
3. Disconnect one solenoid.
4. Measure: **800-1500Ω** = good. OL = dead.
5. Replace valve assembly: $25-60.

Frequently Asked Questions: Error IE
What does error code IE mean on a LG washing machine?
The washer is not filling with water properly.
What usually causes the LG IE error?
The primary cause is: Closed water taps, kinked inlet hoses, or clogged inlet filters.. It may also be caused by temporary sensor misreadings or wiring connection issues.
How do I reset and clear error IE?
Fully open water taps, check hoses for kinks, and clean the inlet mesh filters. If the error persists, unplug the washer from electrical power for 10 minutes to perform a complete logic board reset.
Is it safe to continue using the machine with error IE?
This code has a Low severity level. While the machine might run, resolving the issue early prevents long-term wear on internal parts.
