The thermistor that measures it is a small part on the sump, and when it reads out of range the machine stops rather than run a cycle it cannot control. It is worth separating from the heater code that looks like it — a temperature sensor problem is about knowing, a heater problem is about doing. ### The other ways LG prints this one tE · TE · t 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 - Note whether the cycle stops early or never starts. Both happen with this one. - Cut the power at the breaker for a minute — a genuinely intermittent reading sometimes clears. - Check the hot supply is actually hot at the tap; a machine fed from cold works much harder. - If the code returns, book it. The sensor is a part and the job is a short one. ### Where this goes next The job this usually becomes is [temperature sensor replacement](/services/temperature-sensor-replacement/), 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.
