What Does Error PE Mean?

The LG washing machine PE error code signals a malfunction in the water level pressure sensor, preventing the machine from accurately detecting the water level. This issue often leads to the washer failing to fill or drain properly, potentially halting operation mid-cycle or displaying errors shortly after startup. Troubleshooting may involve checking for blocked hoses or faulty connections, but persistent issues may require professional repair.

Common Symptoms:

  • Washing machine displays PE and may stop operation mid-cycle.
  • Machine may fail to add or drain water normally.
  • Error may appear at startup or shortly after pressing Start.

Possible Causes

  • Faulty water level pressure sensor (pressure switch) (medium)
  • Wiring or connection issue between pressure sensor and control board (medium)
  • Blocked or kinked pressure hose/tube affecting sensor readings (medium)

How to Fix Error PE

DIY Fix Basic Power Reset and Visual Checks

  1. Unplug the washing machine from power for 5–10 minutes to reset internal logic.
