The LG WashCombo is a front-load washer and a heat-pump dryer in one drum. Its codes are the LG washer's — IE, OE, dE, UE, CL — with the drying side's dHE and tE family on top. No duct means no d80 / d90 airflow code; the dry side's trouble is the filters behind the door and the lower panel, the drain and the room's air. Find the code, work the checks, reset.
Covers: WashCombo all-in-one ventless washer-dryers (WM6998HBA, WM6998HVA, WM6998 and the 2024-and-newer WashCombo models) and the older WM3998 combos.
The code as the display prints it; an older spelling sits under it on the card.
LG prints two-letter codes (OE, IE, dE, UE). A lower-case letter is the display's own shape, not a different code.
LG prints an E where a Samsung prints a C: IE is the fill, OE the drain, dE the door, UE the balance, CL the child lock. The display's 0 and O read the same.
The reset: Power off, unplug (or the breaker off) for one full minute, plug back in, run a Rinse + Spin. A code that comes straight back is real.
Two filters: the lint filter in the door rim after every dry, and the drain-pump / condenser filter behind the lower front panel on the manual's schedule.
The plate decides the plug — most WashCombo models run on 120V on their own outlet; a 240V combo follows the dryer's cord and terminal-block rules.
The ThinQ app and Smart Diagnosis read the code and the cycle history; the model and serial plate is inside the door rim.

Fix at homeThe fill did not reach the level in time; the water is not getting to the valve.
Open the taps, clean the screens, straighten the hoses, reset. With everything open and clean, the inlet valve is the part.
Also printed as 0E
Fix at homeThe pump ran and the water did not leave in time. On a combo the drain carries the dry cycle's condensate too, so a long dry can be this code's cousin.
Clean the pump filter, set the hose, clear the drain, reset and run a Spin. A pump that hums with a clean filter is the pump.

Fix at homeFoam filled the drum; the control pauses to let it settle.
Let the cycle finish, run a Rinse + Spin empty, use less detergent.
The water kept rising after the valve should have closed.
A valve that lets water in with the machine off is the inlet valve — close the taps and call it in.
Water rising with the combo off is a stuck inlet valve — close both taps and make the warranty call with the model and serial.

Check, then callThe latch did not report closed or the lock did not engage.
Close firmly and restart. A shut, clean door that still reports open is the lock assembly.
A door that is firmly shut and clean and still reports open is the door lock assembly — a warranty call.

Fix at homeThe drum could not balance the load for the spin.
Bolts out, feet level and locked, load balanced. Unbalance that stays on a level, balanced machine is the suspension — a warranty call.
Not a fault: the control panel is locked and ignores every button.
Nothing to fix — it is a setting.
Also printed as LE1
Check, then callThe motor could not turn the drum — an overloaded drum or a motor fault.
Lighten the load and reset. An LE on an empty drum after the reset is the motor or its sensor — a warranty call.
An LE on an empty drum after one full reset is the drive motor or the hall sensor — a warranty call with the model and serial.
A heat-pump dryer has no vent and no d80 / d90 airflow code — its trouble is the filters, the drain and the room's air.
Also printed as dHF
Check, then callThe dry side could not reach or hold its temperature — the heat pump's air is blocked or a heating part failed.
Clean both filters, give it air, reset. A dHE that returns with clean filters in a cool room is the heat-pump circuit — a warranty call.
A dHE that returns with both filters clean, the grilles clear and the room cool is the drying side's heater or compressor circuit — a warranty call with the model and serial.
Also printed as tE2 · tE3 · tE4
Service callA temperature sensor on the wash or the dry side read open or shorted.
Clean the filters and reset. A tE that stays is the thermistor — a part under warranty.
A tE that returns after the reset with clean filters is the thermistor or its wiring — a warranty call with the model and serial.
The leak sensor in the base saw water — on a combo, often the condensate path.
Fix the hose or the detergent, dry the base, reset. Water in the base with every hose and the drain dry is an internal leak — a warranty call.
Water in the base with every hose and the drain dry is an internal hose or the tub seal — a warranty call with the model and serial.
The power dropped mid-cycle; the control remembers.
Restart the cycle. A PF that repeats on a dedicated, correct circuit is the board.
Every unit leaves with the manufacturer's full factory warranty. The codes below name a part inside the machine — once the checks have ruled out the install, the power and the hoses, call LG's line with the model and serial, and text us if you want a hand with the claim.
All units are surplus inventory (open box, cancelled order, customer return, overstock, or minor scratch & dent). Every unit includes the manufacturer's full factory warranty. Please inspect thoroughly in person before purchasing — cosmetic imperfections or missing accessories are possible.
A fix, a part, or a warranty call — the plate's model and serial plus one line about the symptom is all it takes to tell which.
These pages are educational. Every appliance is a little different — follow the manufacturer's manual and local code, and leave gas, water heater and 240V work to a licensed installer.
