Possible Causes

Failed main control board (PCB), Burnt relay or triac on PCB, Voltage surge damage, Loose mains wiring connection at terminal block

How to Fix / Troubleshooting

Safety first: Unplug the washer before removing any covers. Capacitors on the PCB can retain charge.

  • Check mains supply: Verify that the wall socket is supplying stable voltage by testing with another appliance. Avoid using multi-way adapters or extension leads.
  • Inspect mains cable and terminal block: Remove the rear cover and check where the mains cable enters the machine. Ensure the terminal block screws are tight and there are no signs of burning or melting.
  • Power reset: Leave the washer unplugged for 5–10 minutes to allow the control board to discharge, then reconnect and try again.

If E09 returns immediately or there are visible burn marks on the PCB, the main control board will likely need replacement. This repair involves handling live circuits and should be performed by a qualified technician.
