Possible Causes

Corrupted EEPROM data on main PCB, Power surge damage, Faulty main control board

How to Fix / Troubleshooting

Safety: Unplug the unit before any disassembly.

Steps:

  • 1. Power cycle: Disconnect power for at least 10 minutes to allow capacitors to discharge. Reconnect and check if E9 clears.
  • 2. Check power quality: Plug the unit directly into a wall outlet (no extension leads). Avoid outlets with known voltage issues.
  • 3. Inspect PCB visually: Remove the control panel or rear cover to access the main PCB. Look for burnt components, bulging capacitors, or corrosion.
  • 4. Reseat connectors: Disconnect and reconnect all harnesses to the PCB to ensure good contact.
  • 5. If E9 remains: EEPROM corruption or microcontroller failure is likely. The practical repair is to replace the entire main control board with a new Beko PCB programmed for your model.

Because EEPROM reprogramming requires manufacturer tools, this repair is typically done by an authorized service center.
