Everything the machine washes off the plates that does not leave through the drain stays in the sump, and the filter cylinder there is what catches it. A filter nobody has taken out in two years will stop a perfectly healthy pump. Past that it is the drain hose behind the machine, the high loop or air gap at the sink, a disposal spigot that was never punched out when the machine was installed, and only then the pump itself. ### The other ways LG prints this one OE · 0E · E0 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 - Take the filter cylinder out of the sump floor — it twists — and rinse it under the tap. - Scoop the standing water out first so you can see the sump. - Check the drain hose behind the machine for a kink, and the connection at the sink. - Run a rinse cycle and listen. A pump that hums is blocked; a pump that is silent has failed. ### 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.
