Direct answer
On a supported LG dryer, PS means the electric dryer detected an incorrect power-supply condition. Turn the dryer off and verify the cord terminal and outlet were installed for the model. Then ask a qualified electrician to test both supply legs and neutral/ground arrangement.
What this covers
