When the element or its circuit fails, the machine can still wash, badly, in water it cannot bring up to temperature, and it will tell you rather than pretend. Poor cleaning with no code and poor cleaning with this code are two different calls, which is why the code is worth writing down before the power goes off. ### The other ways LG prints this one HE · HE1 · H E 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 - Check the incoming water is genuinely hot — run the sink tap for thirty seconds first. - Note whether things are also coming out wet, which points at the same circuit. - Cycle the power at the breaker. - A returning HE is a visit: the element is inside the tub and is not a homeowner part. ### 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.
