Evidence linked to this decision
View source: LG USA front-load washer error code listRisk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
PE means the washer received an abnormal water-level or pressure-sensor signal. Stop using it if the visible level does not match the cycle.
Safety first
Stop and check this first
- Stop immediately if the washer overfills, drains continuously or leaks. Keep water away from electrical outlets and do not bypass the level control.
Safe checks you can perform
- Compare the visible level with the cycle state
- Close water and disconnect power
- Do not open the pressure system
Leave these tasks to a qualified professional
- Do not attempt this professional task: Test the complete level-sensing path
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Test the complete level-sensing path
What they doA technician should verify the pressure chamber, tube, sensor, wiring and control interpretation against the service data.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Compare the visible level with the cycle state
Stop the programme if the washer appears overfilled, empty when it should contain water or continues filling unexpectedly.
Stop immediately if the washer overfills, drains continuously or leaks. Keep water away from electrical outlets and do not bypass the level control.

What it means
LG defines PE as a pressure or water-level sensing error on compatible washers. The code identifies the measurement path, not whether the sensor, hose, connector or control is at fault.
