LG Appliance Error Codes: What Supers Should Know
LG washer, dryer and refrigerator codes from LG's US Help Library, with the resets and checks LG recommends and the fridge codes that always need service.
On LG washers, IE means water isn't coming in, OE means it isn't draining, UE means an unbalanced load and dE means the door or lid isn't locking, and all four usually clear with a check at the machine. On LG dryers, d80, d90 and d95 mean the exhaust vent is badly restricted. On LG refrigerators, almost every code is a part fault, and LG's advice is to request service.
The tables below come from LG's US Help Library. LG notes that codes vary by model, so match the code to the right appliance and keep the model number from the tag handy.
LG washer codes
Most of these appear on LG front-load washers. Where LG gives a different meaning on top-load washers, the row says so.
| Code | What it means | What the tenant or super can safely check | Send a work order? |
|---|---|---|---|
| IE | Not enough water coming in | Supply taps fully open, hoses not kinked, inlet filters clean | If supply is fine and it returns |
| OE | Water can't drain | Drain hose not kinked, clogged or frozen; on front-loaders, clean the drain filter | If those are clear |
| UE, Ub | Unbalanced load | Rearrange the laundry; add an item or two to a very small load | Only if it happens on normal loads |
| dE, dE1, dE2 | Door (or top-load lid) not closed or not locking | Close it firmly; unplug 10 seconds and restart | If it persists |
| LE | Motor overloaded and locked | Let it rest 30 minutes, then restart the cycle | If it returns |
| FE | Overfilling, usually a faulty water valve | Close both taps, drain the washer, unplug until it's repaired | Yes |
| PE | Water level sensor malfunction | Unplug 10 seconds and restart | If it returns |
| tE | Heating error, usually a faulty thermistor | Unplug 10 seconds, drain, restart | If it persists |
| CE | Motor over-current or drum not reaching speed | Unplug 10 seconds and try a cycle | If it persists |
| FF | Washer is frozen | Check hoses and drain filter; warm water in the drum | If it doesn't run once thawed |
| SUD | Too many suds; a suds-reducing routine adds about 2 hours | Use less detergent | No |
| PF | Power failed during a cycle | Restart the cycle | No |
| CL | Child lock is on | Hold the Child Lock button 3 seconds | No |
| tCL | Tub clean reminder | Run the Tub Clean cycle | No |
| uE (small u, top-load) | Washer is rebalancing on its own, up to three tries | Nothing | No |
LG dryer codes
| Code | What it means | What the tenant or super can safely check | Send a work order? |
|---|---|---|---|
| d75, d80, d90, d95 (or Flow Sense bars) | Exhaust vent about 75%, 80%, 90% or 95% blocked; on gas dryers, d80 can mean no gas | Clean the lint filter; use smaller loads; check the hose behind the dryer for crushing or kinks; outside flapper opens fully | If it persists: the duct run needs inspection and cleaning |
| dE | Door not fully closed | Lint filter fully seated, nothing caught in the door; unplug 5 seconds and restart | If it returns |
| F0 or flashing Insert Filter | Lint filter not seated, so the dryer stops | Remove and reinsert the lint filter | If it continues |
| tE1, tE3 | Thermistor (temperature sensor) problem | Unplug, hold Start/Pause 5 seconds, plug back in, run a cycle | If it returns |
| TE4 | Thermistor reads out of range | Nothing | Yes |
| HS | Humidity sensor error; the dryer runs about 2.5 hours | Wipe the sensor bars under the lint filter with a damp cloth, let them dry | If it persists |
| nP | No current at the heater (home wiring) | Cord fully plugged in; breaker off 10 seconds, back on | Yes if it still won't heat; the outlet needs an electrician |
| PS | Improper voltage in the power cord | Breaker off 10 seconds, back on | Yes if it persists |
| Gas (9A5) | Dryer isn't getting gas | Don't touch the gas line | Yes |
| PF | Power outage interrupted it | Same reset as tE1 | If it persists |
| nE, nF | Wi-Fi module problem | Nothing | Only if the Wi-Fi features matter |
| CL | Child lock on | Hold Child Lock 3 seconds | No |
Pass one thing on to tenants: LG treats d90 and d95 as needing immediate attention and advises not using the dryer until the exhaust system is cleaned and repaired.
LG refrigerator codes
LG fridge codes usually start with E, r or Er (for example Er FF), depending on the model.
| Code | What it means | What the tenant or super can safely check | Send a work order? |
|---|---|---|---|
| FF | Freezer fan fault; frost around the fan often stops it | Nothing; LG says request service | Yes |
| rF | Refrigerator fan fault | Nothing; LG says request service | Yes |
| CF | Condenser fan fault; the compressor overworks | Nothing | Yes |
| IF | Ice maker fan fault | Check for an obstruction | Yes |
| dH (FdH, dHF) | Defrost not working; the evaporator may be iced over | Nothing | Yes |
| FS, rS, r2, dS, rT | Temperature or defrost sensor fault | Nothing | Yes |
| CO, C1 | Communication error between boards or display | Nothing | Yes |
| CH, CL | Refrigerant leak, high or low side | Nothing | Yes |
| FU | Freezer not getting cold enough | Unplug 60 seconds; plug into a wall outlet, not a power strip; check door seals and vents | If it continues |
| gF | Water flow sensor fault | Unplug 60 seconds; water tap fully open, hose not kinked | If it continues |
| tt | Water tank missing or not seated | Reseat the tank | If it persists |
| Demo mode (no code, no cooling) | Display mode for stores; cooling off | Hold Fridge and press Express Frz 3 times (or hold both 3 seconds) | No |
To see the current code on many models, press Freezer Temperature and Express Frz together for at least 3 seconds.
What a super can try first
These come from LG's own steps. None involve opening the appliance or touching gas.
- Washer reset. For dE, PE, tE and CE, LG's first step is unplugging for 10 seconds and restarting.
- Dryer reset. Unplug or trip the breaker, hold Start/Pause for 5 seconds with the power off, restore power and run a cycle.
- Water supply. For IE, open both taps fully, straighten the hoses and clean the inlet filters.
- Drain. For OE, check the drain hose, then clean the drain filter on a front-loader. Have towels ready.
- Lint and vent. For d-codes, clean the lint filter, wash it with warm water and a soft brush, check the hose behind the dryer, and make sure the outside flapper opens.
- Fridge power. For FU and gF only, unplug 60 seconds and plug straight into a wall outlet.
When to send a work order
Send one right away for:
- FE on a washer. Close both taps first.
- Any LG refrigerator fan, sensor, defrost, communication or refrigerant code (FF, rF, CF, IF, dH, the sensor codes, CO, CH, CL). LG's step for each is to request service.
- Gas (9A5) on a gas dryer.
- TE4, or nP that still won't heat.
Send one after a single reset and recheck for:
- IE, OE, dE, LE, PE, tE or CE that come back.
- d80 that persists after the lint filter and connector hose are cleared. The duct run likely needs cleaning.
- d90 or d95 right away if the lint filter and hose are already clean. LG says not to use the dryer until the exhaust is fixed.
- tE1 or HS that return.
- FU or gF after the 60-second power-off.
Include the exact code, the model and serial number, and what you tried.
Next step
If an LG code is still showing after these checks, request service for the unit. Our pages on refrigerator repair and washer and dryer repair cover what we work on.
