When the reading fails outright the machine reports HS; when it merely drifts, you get the far more common complaint of a cycle that jumps from an hour to a minute, or one that stops with the load still damp. The cause is nearly always a film of fabric softener across the strips, and it wipes off. ### The other ways LG prints this one HS · H S 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 - Open the door and find the two metal strips inside the drum opening. - Wipe them with a little rubbing alcohol on a cotton pad until they are bright. - Cut back on liquid fabric softener and dryer sheets, which is what films them. - Run a normal cycle. If the code returns after cleaning, 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.
