When it stops being believable the machine will not carry on, because filling a drum you cannot measure is how a laundry room floods. As with the dishwasher, the hose blocks or perishes more often than the sensor fails. ### The other ways LG prints this one PE · E33 · 1PE 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 - Note whether the machine overfills, underfills or refuses to start — all three come from here. - Cut the power for five minutes. - Check the drain filter and hose are clear, since a blocked sump affects the reading. - Book it if the code returns; the hose runs under the tub. ### 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.
