LG Dryer Error Code PS
The dryer is detecting the wrong voltage from its power cord; LG says the usual cause is the white and red cord wires swapped at the terminal block during installation. Checking the breaker and outlet is safe to do yourself, but the terminal block wiring itself is a job for the installer or an electrician.
Common causes
- White and red power cord wires reversed on the dryer's terminal block after installation
- Power cord connected incorrectly
- House supply voltage incorrect
- Blown fuse or tripped circuit breaker
What to check, in order
- Switch the dryer breaker off for at least 10 seconds, then back on, and confirm the plug is fully seated in a 240V outlet
- If the dryer is newly installed or the cord was just replaced, have the installer check the cord wiring at the terminal block
- Have a qualified electrician confirm the outlet supplies the voltage shown on the dryer's rating plate
- If the supply and cord wiring both check out and PS returns, book service
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code PS, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.

Start yourself: the checks on this page cover the causes you can reach without opening the machine up. If they point to a faulty part, testing or replacing it is usually a technician job.
How do I clear LG PS?
Fix the cause first — clearing the code on its own brings it straight back. Then restore power and water, run the shortest programme, and watch the stage where the code appeared. If the programme finishes with no code, it is cleared.
