# Washer error code PS

### What PS means on this make

The washer measures its own supply and refuses to run on one it does not trust, which is protective rather than fussy: a motor and a board fed brownout voltage do not last. In a South Florida summer this is a real code rather than a theoretical one. It is also the code most likely to be about the building rather than the appliance, and that is worth establishing before anybody quotes for a part.

### The other ways LG prints this one

PS · pS

LG publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with — OE, E03 and E21 are one condition on a washer, and Er dS, F dS and r dS are one sensor on different evaporators. They are one page here, so whichever of them you searched for, this is the right page.

### Where this appears, and why not to clear it

On the appliance’s own display. LG reports errors two ways: machines with a digital display show a code, and the laundry machines without one blink their indicator lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power. On a refrigerator you can also force the last code back onto the display by holding Freezer Temperature and Express Frz together for three seconds — LG documents that, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.

### What to do about it

- Take the machine off any extension lead or power strip and plug it into the wall.
- Note whether lights elsewhere in the home dim when heavy appliances start.
- Check whether it happens at a particular time of day.
- If the supply is suspect, an electrician is the right call before an appliance engineer.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 419-0291](tel:+13054190291) and describe what the panel is doing before booking anything.
