What we can confirm
Code OPn, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
OPn
The machines with a bulk dispenser hold weeks of detergent in a tank and meter it out per load. This family of codes covers that tank: a drawer left open, a cartridge not seated, a level that has run out, or the sensing that watches it. Nothing about the wash is broken, and the machine will run on a manual dose while it waits for attention.

What it narrows down to
The bulk detergent dispenser is open, empty, or not reporting

On the same appliance
What else belongs to the washers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
The machine has finished washing and cannot get rid of the water
The machine is not filling, or is filling too slowly to finish in time
The drum cannot spin the load safely because it is on one side
The machine cannot prove the door is shut, so it will not start or will not open
The motor is overloaded or cannot turn
The machine cannot measure how much water is in the drum
The cycle was interrupted by the power going away
The machine cannot read the water temperature
The machine has found more suds than it can spin through, and is adding a rinse
The machine believes water in it has frozen
Not an error — the machine has counted enough loads to want cleaning
Not an error — the panel is locked

The other ways LG prints this one
OPn · Ed1 · Ed2 · Ed3 · Ed4 · Ed5 · Ed · OP
LG publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with — OE, E03 and E21 are one condition on a washer, and Er dS, F dS and r dS are one sensor on different evaporators. They are one page here, so whichever of them you searched for, this is the right page.
Where this appears, and why not to clear it
On the appliance's own display. LG reports errors two ways: machines with a digital display show a code, and the laundry machines without one blink their indicator lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power. On a refrigerator you can also force the last code back onto the display by holding Freezer Temperature and Express Frz together for three seconds — LG documents that, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.
What to do about it
- Push the dispenser drawer fully shut. It is the commonest cause by a distance.
- Check the tank is not empty and the cap is closed properly.
- Add detergent by hand for now — the machine will wash normally.
- If the code persists with a full, closed dispenser, book it.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 419-0291 and describe what the panel is doing before booking anything.
