LG Washing Machine PS Error

Last reviewed 11 November 2026 · Checked against LG's official support documentation and model manuals
PS
A power-supply problem serious enough that the appliance stops because it cannot continue the programme. LG notes PS is sometimes misread as P5 — S and 5 look the same on a seven-segment display; LG's code is PS.

Applies to front-load washers on LG's list. LG groups PS under its 'others' control codes with E80, nC, nE and nF — but PS adds a rule of its own: do not use a power strip; plug the washer directly into a wall outlet.

What to check first

PS is the power member of LG's control family: a power-supply problem that stops the appliance mid-programme because it cannot continue. It is also the family's most misread code — LG itself notes that PS is sometimes reported as P5, because S and 5 are indistinguishable on a seven-segment display. The code is PS.

PS is the one member of the family with a second home check beyond the reset. LG's instruction is specific: the washer must not run through a power strip — plug it directly into a wall outlet. This page covers PS on its own; the whole family is introduced on the control & connection family overview.

Safety first

Common causes

A power-supply problem inside the machine's supply path

LG's definition of PS is the fault itself: a power-supply issue serious enough that the appliance stops because it cannot continue the programme. Beyond the reset and the supply arrangement below, LG publishes no owner-level cause — the rest is a service diagnosis.

Running through a power strip

The one supply cause LG names by instruction: do not use a power strip — plug the washer directly into a wall outlet. A strip or multi-way adapter between the washer and the wall is the first thing to remove before judging PS a machine fault.

Step-by-step checks

  1. Read the display twicePS and P5 are the same shapes on a seven-segment display, and LG's code is PS. Write down exactly what is shown before resetting anything.
  2. Fix the supply firstMove the plug to a wall outlet directly — no power strip, no multi-way adapter — before judging the reset a failure, per LG's instruction for PS.
  3. Reset for 60 secondsUnplug the washer, wait a full 60 seconds, plug it back in (directly into the wall outlet) and restart.

When to call a technician

If PS persists after the reset on a direct wall-outlet connection, LG's front-load list directs you to service. Quote PS — not P5 — when booking, and say whether the machine had been running through a power strip; both details shape the technician's first test.

Model differences that matter

Machine typeWhat changes
Front loadThe family is documented on LG's front-load list: E80, nC, nE, nF and PS, each with the 60-second reset and the service ending; PS adds the direct-to-wall-outlet rule.
Connected modelsnC, nE and nF only exist where the hardware does — NFC and Wi-Fi modules. A washer with no connectivity cannot show them; E80 and PS are the members any front loader can produce.

Questions people ask about PS

Is it P5 or PS on my display?

PS, in all likelihood — LG itself flags this: the power-supply code is sometimes reported as P5 because S and 5 look the same on a seven-segment display. LG's code is PS.

Why does a power strip matter?

LG's instruction for PS is explicit and it is the only supply rule it publishes for the code: do not use a power strip — plug the washer directly into a wall outlet. Follow it before treating PS as a machine fault; a PS that only appears through a strip has its first suspect already named by LG.

PS or PF — what is the difference?

PF reports that the power supply was interrupted during a cycle — an outage event, with its own restart guidance. PS reports a power-supply problem that stops the appliance because it cannot continue the programme — a fault state, with the direct-to-wall-outlet rule and a service ending if it persists.
