How to Fix / Troubleshooting

Safety first: Unplug the appliance. Do not touch PCB tracks or components with power applied.

Step-by-step checks:

  • Power reset: Leave the machine unplugged for at least 10–15 minutes to allow capacitors to discharge, then reconnect and test. This can clear transient faults.
  • Inspect PCB connections: Remove the top cover and access the main control board. Check all multi-pin connectors for secure fit. Reseat each connector one at a time.
  • Check for visible damage: Look for burnt components, darkened areas, or corrosion on the PCB. If present, the board will likely need replacement.
  • Verify supply voltage: Ensure the wall outlet provides stable voltage within specification. Avoid using long extension leads.

When to call a technician: Control board replacement and firmware programming (if required) should be performed by a qualified technician.
