Your LG washing machine has stopped mid-cycle with a two-letter code on the display. Before you start worrying, it's worth knowing that LG's system is more readable than most -- the letters usually abbreviate the fault. OE is outlet error. IE is inlet error. UE is unbalanced error. The pattern holds across the range, which means a quick read of the code often tells you roughly what's wrong before you've done anything else.
Some of these you can fix in five minutes. Others… you’ll need to call one of our technicians at National Appliance Repairs. The difference matters, so this guide covers each code -- what it means, what's likely causing it, and what to do next.
How the Error Code System Works
LG washers run sensors throughout the machine monitoring water intake, water levels, drum balance, door lock status, motor speed, and temperature. When a reading falls outside expected parameters for long enough, the control board stops the cycle and shows a code. The machine isn't broken in all cases -- sometimes it's flagging a temporary condition. But the code won't clear until the condition is resolved.
LG Washing Machine Error Code Reference Table
| Error Code | What It Means | Usually DIY? |
|---|---|---|
| OE | Drainage problem -- water not draining | Sometimes |
| IE (or 1E) | Water inlet problem -- machine not filling | Sometimes |
| UE | Unbalanced load | Usually yes |
| LE | Motor or rotor position sensor fault | No |
| dE | Door not properly closed or latch faulty | Sometimes |
| tE | Temperature sensor (thermistor) fault | No |
| FE | Overfill -- too much water in drum | Sometimes |
| PE | Water level pressure sensor fault | No |
| CE | Motor overcurrent error | No |
| PF | Power failure mid-cycle | Usually yes |
| CL | Child lock active (not a fault) | Yes -- deactivate it |
OE -- Drainage Error
The most commonly reported LG error in Australia. OE means water isn't draining within the timeframe the machine expects, so it stops to prevent overflow.
Start here:
- Clean the drain pump filter. On most LG front-loaders it's behind a small access panel at the bottom front of the machine. Lay a towel down, unscrew the filter cap slowly, let the residual water drain out, and clear any lint, coins, or debris from the filter housing.
- Check the drain hose at the back for kinks or sharp bends that restrict flow.
- Check that the drain hose isn't inserted too far into the standpipe -- this can create a siphon effect that interferes with drainage.
LG's own support documentation recommends cleaning the drain filter monthly. Most OE errors clear after a filter clean. If the code returns with a clean filter and clear hose, the drain pump motor has likely failed and needs replacement by a technician.
IE -- Water Inlet Error
IE (shown as 1E on some older models) means the tub isn't filling with water within the allocated time. Usually a supply issue rather than anything wrong with the machine itself.
Check these first:
- The tap at the back of the machine -- make sure it's fully open, not just partially turned
- The inlet hose for kinks or bends
- The mesh filter screens where the hose connects to the machine -- sediment and mineral deposits clog these over time, particularly in harder-water areas like regional Western Australia and parts of regional Queensland
- Water pressure at the mains -- low pressure can trigger IE even with everything else correct
The Australian Drinking Water Guidelines note considerable variation in water mineral content across Australian states. In hard-water areas, inlet filter screens need cleaning more frequently than manufacturers typically suggest.
If supply and pressure check out fine, the inlet valve itself has likely failed. That's a parts replacement job.
UE -- Unbalanced Error
UE means the drum's load is distributed unevenly and the machine won't spin at full speed because of the vibration risk.
A lowercase "uE" means the machine is still trying to self-correct -- it'll add a small amount of water, agitate to redistribute the clothes, drain, and attempt spin again. Let it work through this before intervening. An uppercase "UE" means it failed three times and needs your help.
Open the door, redistribute the clothes evenly around the drum, and restart. Check the machine is level -- use a spirit level across the top and adjust the leg height with a spanner if needed.
If UE keeps appearing with well-distributed loads and a level machine, worn shock absorbers (front-loaders) or suspension rods (top-loaders) are the likely culprit. That's a mechanical repair. See our dedicated LG Washing Machine UE Error guide for a full walkthrough.
LE -- Motor Error
LE points to a problem with the rotor position sensor or the motor assembly. The sensor tells the control board the exact speed and position of the drum motor so it can fire the right induction coils in sequence. When the reading is missing or wrong, the machine stops rather than run the motor blind.
Not a DIY repair. Diagnosing LE involves testing the stator, rotor, and position sensor with a multimeter, and replacing whichever component has failed.
dE -- Door Error
The door interlock is a hard safety requirement -- the machine won't run with the door open or unlatched. A dE code means the control board hasn't received confirmation that the door is properly closed.
Try these:
- Open the door and close it again firmly
- Check for laundry caught in the door seal stopping it from closing fully
- Inspect the door seal for damage
- Look at the latch mechanism for wear or breakage
A worn or broken latch is a single-visit repair for a technician.
tE -- Temperature Sensor Fault
The thermistor monitors water temperature throughout the cycle. A tE code means it's reading outside the expected range -- or not reading at all. Without reliable temperature data, the machine won't heat water correctly, which matters most for cycles that rely on heat to sanitise -- towels, bed linen, nappies. This is a component replacement job.
FE -- Overfill Error
FE means the machine has detected water above the expected level in the drum. The usual cause is an inlet valve that isn't closing fully, allowing water to keep entering after the fill phase ends. A faulty water level pressure sensor can also produce FE. Turn the machine off at the power point if water looks visibly high in the drum, and call a technician before running another cycle.
PF -- Power Failure
PF records that the machine lost power mid-cycle -- a brief outage, a tripped breaker, or an accidental unplug. It's a record, not a fault. Press Power, restart the cycle, and it should run normally.
CL -- Child Lock
Not an error. CL means the child lock feature is active and the buttons are disabled. To turn it off, hold the temperature and eco/rapid buttons simultaneously for about three to four seconds. The exact combination varies by model -- check your manual if this doesn't work.
FAQ
How do I reset an LG washing machine error code?
Turn the machine off at the power point, wait 30 seconds, and turn it back on. If the error reappears straight away, the fault is still present and a reset won't help.
Why does my LG washing machine keep showing OE?
A blocked drain pump filter is the cause in most cases. Clean it first. If OE returns with a clean filter and clear drain hose, the pump motor has likely failed.
Can I use my LG washing machine with a dE error showing?
No. The machine won't start a cycle with the door unconfirmed closed -- it's a safety interlock. Fix the latch or seal before running a cycle.
What's the difference between tE and LE on an LG washer?
tE is a temperature sensor fault; LE is a motor or rotor position sensor fault. Both require a technician.
My LG washer shows CL -- is something wrong?
No. Child lock is active. Hold the relevant buttons for three to four seconds to turn it off.
Conclusion
LG's error code system rewards a quick read before reaching for the phone. OE, IE, and UE cover the majority of call-outs and most have a user-level fix to try first -- clean the drain filter, check the supply tap, redistribute the load. Motor faults (LE), sensor faults (tE, PE), and overfill errors (FE) are different -- those need a technician before the machine is run again. Wherever you are in Australia, National Appliance Repairs has LG-experienced technicians available across all major cities, with same-day bookings and a 12-month warranty on every part.
