What PS (Power Supply Issue) Means
PS indicates a power supply issue that stops the washer from continuing its program, per LG's front-load washer Help Library article, which specifically notes PS can sometimes display as P5 since the letter S and digit 5 look similar on a seven-segment display.
Common Causes of PS (Power Supply Issue)
- Washer plugged into a power strip rather than directly into a wall outlet
- Insufficient or unstable power supply to the outlet
- Internal power supply component fault
🔧 One Safe Check You Can Try
Do not use a power strip or extension cord - plug the washer's power cord directly into a wall outlet - then unplug for 60 seconds and restart.
⚠ Why You Shouldn't Go Further Than That
- If PS persists even when plugged directly into a dedicated wall outlet, that points to either a house electrical issue (have an electrician check the outlet's voltage) or an internal power-supply fault needing a technician.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
