How to Fix / Troubleshooting
Safety: Ensure the outlet is safe; do not work on live circuits.
Steps:
- Check outlet: Test the wall socket with another appliance to confirm power is present.
- Inspect plug and cord: Look for cuts, burns, or loose pins. Replace the cord set if damaged.
- On/off switch: Access the control panel and test the power switch for continuity when pressed.
- Internal fuse: Some Ariston boards have an internal fuse; inspect and replace only with the same rating if blown, and investigate why it blew.
- Board replacement: If the low-voltage power supply on the PCB is dead (no standby voltage), the main control board will need replacement.
Note: If fuses blow repeatedly, consult a qualified technician to check for shorts.
