The dryer is seeing incorrect voltage from its power cord. LG notes this can happen when the cord's wires are connected to the wrong terminals at the back of the dryer, for example after a new installation or a cord change.

Safety first: unplug the dryer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG PS

Reset the breaker
Switch the dryer's breaker off for at least 10 seconds, then back on, and try a cycle.
Check the outlet and installation
Make sure the cord is fully plugged into a grounded 240V outlet that matches the rating plate. If the dryer was just installed or the cord was just changed, ask the installer to recheck the cord connections against the 3-wire or 4-wire instructions in the manual. Do not open the terminal block cover while the dryer has power.

When to call a technician

Have the installer, a licensed electrician or an LG technician correct the cord wiring. If the wiring is correct and the code continues, book a repair.
