Possible Causes

Corrupted EEPROM data on main PCB, Faulty main control board, Power surge damage, Incorrect replacement PCB not programmed for model

How to Fix / Troubleshooting

Safety first: Disconnect the appliance from mains before accessing electronics.

Step-by-step checks:

  • Power reset: Leave the dishwasher unplugged for at least 10 minutes to allow capacitors to discharge, then reconnect and test. This can clear transient faults.
  • Check supply quality: Ensure the outlet provides stable voltage and that there are no frequent power cuts or surges. Use a surge protector if necessary.
  • Inspect PCB: Remove the control panel and inspect the main PCB for burn marks, swollen components, or corrosion. If visible damage is present, replacement is required.
  • Programming: If the PCB was recently replaced, verify that the correct Vestel board and firmware version were installed for your exact model. Some boards require programming with model-specific parameters.

EEPROM and firmware issues generally require a new control board or service tools. Contact an authorized Vestel service center if E9 persists after a power reset.
