How to fix it

  1. Unplug the washer for 10 minutes; sometimes a clean power cycle clears a transient.
  2. Pull the rear panel and locate the MCU (small board in a metal box near the motor).
  3. Look for water staining, corrosion on the pins, or visibly burnt components.
  4. If you see corrosion: fix the leak source first, then replace the MCU.
  5. If clean but still throwing F0E7 on every start, replace the MCU.

Why it happens
