LG Washing Machine OPn & Ed1–Ed5 Codes (ezDispense)
Applies only to LG washers with the ezDispense automatic dispensing system. If your washer has a plain manual dispenser drawer, these codes do not apply to it.
What to check first
- OPn: push the detergent drawer fully in until it is completely inserted — and leave it closed during operation.
- Ed1–Ed4: check the detergent and softener types are correct, and clear any residue blocking flow in the tray. (Liquid softener only in the softener dispenser — powder softener goes directly in the drum.)
- Ed5: unplug the washer, wait 60 seconds, and restart.
- If any of these codes persist after its check, LG directs you to service.
ezDispense models dose detergent and softener automatically from reservoirs in the drawer, which gives them a fault family no other LG washer has: codes for the drawer itself (OPn), for the two dosing pumps and their circuits (Ed1 to Ed4), for board communication (Ed5), and a maintenance display (dcL) that is not a fault at all. LG documents all of them in one block on its front-load list, and this page follows that grouping.
Read the entry that matches your display. Most of these codes have one physical check attached — the drawer, the tray, the liquids — before LG's service ending, and the checks are cheap to do properly.
Safety first
- Unplug the washer before removing the dispenser drawer fully or cleaning deep in the dispenser housing.
- Detergent and softener residue is slippery and an eye irritant: rinse hands after handling the tray, and keep spilled liquid off the floor where it is a slip hazard near a machine you are leaning into.
- Stop condition: stop using the machine and unplug it — and do not run it again until it has been checked — if you smell burning, see smoke, find damaged electrics (a scorched plug, a melted or cut cable), or water is leaking in quantity.
What each code means
OPn — drawer not fully inserted
The washer was operated without the detergent drawer completely inserted, or the drawer was opened during operation. LG's resolution is mechanical: ensure the drawer is completely inserted. A persistent OPn after that goes to service.
Ed1 — detergent pump fault detected
The liquid detergent amount did not decrease as expected, and the machine detected a faulty detergent pump. Check the detergent type is right for the reservoir and that residue is not blocking the tray's flow path.
Ed2 — detergent pump open circuit
The same “amount did not decrease” symptom as Ed1, with the cause named electrically: an open circuit in the detergent pump. Tray checks first; a wiring/circuit fault is service.
Ed3 — softener pump fault detected
The softener amount did not decrease; a faulty softener pump was detected. LG's checks: only liquid softener in the dispenser (powder softener goes manually in the drum), and residue cleared from the tray.
Ed4 — softener pump open circuit
Ed3's electrical twin: softener not decreasing, with an open circuit in the softener pump named as the cause.
Ed5 — PCB communication issue
A communication problem between the machine's printed circuit boards. LG's resolution is the reset: unplug, wait 60 seconds, restart — then service if it persists.
dcL — Nozzle Clean is running (not an error)
dcL means the ezDispense Nozzle Clean function is activated — a maintenance routine for the dispensing nozzles that runs about 16 minutes. LG's note: the compartments must be emptied and cleaned, then filled with water to the max line for the function. Consult your model manual; dcL is the machine maintaining itself, not failing.
Step-by-step checks
- Seat the drawer (OPn)Push the detergent drawer in until it is completely inserted — fully home, not nearly. Run a cycle without opening it mid-operation.
- Audit the liquids and the tray (Ed1–Ed4)Confirm the reservoirs hold the right products: liquid detergent in the detergent side, liquid softener only in the softener side. Remove the tray and clear residue blocking its flow paths, then re-seat it fully.
- Reset for Ed5Unplug the washer, wait 60 seconds, plug it back in and restart. A communication fault that survives its reset is LG's service case.
- Leave dcL aloneIf dcL is displayed, the Nozzle Clean function is active. Follow your manual for the compartment preparation rather than interrupting it.
When to call a technician
LG's front-load list ends each of these codes the same way: if OPn, Ed1, Ed2, Ed3, Ed4 or Ed5 persists after its published check, request service. Quote the exact code when booking — Ed1 and Ed2 look identical from the symptom (detergent not decreasing) and differ in cause, which is the technician's first fork.
Model differences that matter
| Machine type | What changes |
|---|---|
| ezDispense models | The whole family lives here: OPn for the drawer, Ed1/Ed2 for the detergent pump (fault / open circuit), Ed3/Ed4 for the softener pump (fault / open circuit), Ed5 for PCB communication, dcL for the Nozzle Clean function. |
| Manual-dispenser models | None of these codes apply — there is no automatic dosing system to report them. Sud and FE are the dispenser-adjacent codes on standard models. |
One-page checklist
- Exact code read from the display (OPn, Ed1–Ed5, or dcL)
- OPn: drawer pushed fully home and left closed during the cycle
- Ed1–Ed4: liquid types confirmed; tray residue cleared; powder softener kept out of the dispenser
- Ed5: 60-second unplug reset done
- Code persists — service booked with the exact code quoted

Questions people ask about the ezDispense codes
My detergent level never goes down but there is no Ed code. Is the pump broken?
The Ed codes are how the machine reports exactly that detection — Ed1/Ed3 when it detects a faulty pump, Ed2/Ed4 when it names an open circuit. If the level truly never falls with no code showing, work through the tray checks here (right liquids, residue cleared) and then treat it as the same service conversation, with your observation as the evidence.
Is dcL an error? It looks like one.
No — dcL is the ezDispense Nozzle Clean function activated: a maintenance routine (about 16 minutes) for the dispensing nozzles. LG's guidance is to consult the manual for the function — the detergent and softener compartments are emptied and cleaned, then filled with water to the max line.
Can I use powder softener in the ezDispense drawer?
No — LG's guidance for Ed3/Ed4 is explicit: only liquid softener belongs in the dispenser; powder softener is added manually, directly in the drum.
