LG Washer PE Code: Meaning & Fixes
- Meaning
- Water level sensor error: the pressure sensor that measures the water level in the tub is malfunctioning or can't detect the level correctly.
- Can I fix it?
- Sometimes, may need a pro
- Seen on
- LG front-load and top-load washers and the washer in LG WashTower units.
PE on an LG washer means the water level (pressure) sensor isn’t reading the water level correctly. It’s a sensor fault, not an overfill like FE. LG’s fix is to unplug the washer, wait 10 seconds on front loaders or 5 minutes on top loaders and WashTower units, then plug it back in. If PE returns, request service.
Try this first
- Unplug the washer: 10 seconds for front loaders, 5 minutes for top loaders and WashTower units.
- Plug it back in and restart the cycle.
- If the washer is in a humid room such as a bathroom, improve ventilation; LG says moisture in the air can trigger PE.
- If PE comes back, request repair service.
What causes PE
| Cause | What you notice | What to check |
|---|---|---|
| Temporary sensor reading fault | PE once, then normal after unplugging | Power reset |
| Humid installation room | PE on a washer installed in a bathroom or damp space | Unplug for 5 minutes, ventilate the room |
| Clogged or kinked hose to the water level sensor | PE with odd fill levels | Needs a technician |
| Failed water level (pressure) sensor | PE returns after every reset | Needs a technician |

-
Unplug the washer
Pull the power cord. On front loaders LG says 10 seconds is enough; on top loaders and WashTower units, wait 5 minutes.
Safety: If there is water on the floor, keep it away from the outlet and cord, and unplug with dry hands.
-
Plug in and restart
Reconnect the power and restart the cycle.
-
Check the room
If the washer sits in a bathroom or other humid room, LG says moisture in the air may cause PE. Ventilate the room and keep the lid or door area dry.
-
Request service if PE returns
If PE shows again, stop using the washer and request repair service.
Safety: The water level sensor and its hose sit inside the cabinet next to mains wiring. Leave them to a technician.
When to call a technician
Try the power reset once. If the PE error persists, LG says the washer requires repair service to check the water level sensor and its hose.
Questions people ask
What's the difference between PE and FE on an LG washer?
PE means the water level sensor itself isn't reading correctly. FE means the tub actually overfilled, usually because the inlet valve didn't close. FE starts with closing the taps and draining; PE starts with unplugging.
How long should I unplug my LG washer for a PE code?
LG's front-load instructions say 10 seconds. For top loaders and WashTower units, LG says to wait 5 minutes before reconnecting.
Can a humid bathroom cause PE?
Yes. LG says moisture in the air of a humid room, such as a bathroom, may cause the PE error.
