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. ### 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](/services/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](tel:+13054190291) and describe what the panel is doing before booking anything.
