How do you do a hard reset on a LG?

To do a hard reset on an LG appliance, which includes LG dryers, washers, and other electronics, you perform a power cycle that fully discharges the control board and clears temporary faults, error codes, and lockups. For an LG dryer or washer, turn the machine off with the Power button, then unplug it completely from the wall outlet. For electric dryers, you should also turn off the double 30-amp circuit breaker in your electrical panel to ensure no power remains. Leave the appliance unplugged for at least 5 to 10 minutes, which allows capacitors on the main control board to drain. While it is unplugged, press and hold the Start/Pause button for 5 seconds to dissipate residual charge. After waiting, plug the appliance back in or turn the breaker back on, press Power, and run a test cycle with no clothes on Time Dry for 10 minutes to confirm it heats and tumbles. For an LG TV or phone, a hard reset involves holding the Power button for 10 seconds or using the hardware keys. A hard reset will not fix mechanical failures like a broken belt, blown thermal fuse, or failed heating element, but it often clears electronic glitches like d80, d90, tE, or LE error codes and control lock issues.
