LG washer PE error: water-level or pressure sensing fault
PE indicates a water-level/pressure-sensing problem. After one power reset, persistent PE needs service rather than repeated fill/drain experiments.
Start here
PE indicates a water-level/pressure-sensing problem. After one power reset, persistent PE needs service rather than repeated fill/drain experiments.
Check these first
- Note whether the tub is visibly too full, too empty or normal when PE appears.
- Power-cycle once.
- Check for obvious hose/install issues before service.
Fix it in this order
- Stop the cycle.
- Power-cycle once.
- If PE returns, service the pressure sensor/air hose/control path.
Evidence to keep
- PE code
- Water level when it occurs
- Cycle point
Do not make it harder
- Bypassing sensing
- Running unattended with unstable water level
How you know it is fixed
- The washer measures/fills normally and PE does not recur.
If the obvious fix does not work
- If PE accompanies an actual overfill, close water supply and treat the water-control problem as urgent.
- If PE is intermittent, record the cycle point and water level to help diagnosis.
If this still isn't resolved
- LG service
