Freezer shows error code E6 and the display or internal lights may flicker or reset intermittently.

Safety first: Always unplug the freezer before inspecting the power cord or control board.

• Check outlet: Plug another appliance or a lamp into the same outlet to verify stable power. Avoid using extension cords or multi-plug adapters.
• Inspect power cord: Look for cuts, kinks, or burn marks along the Ariston freezer's power cable. Ensure the plug fits firmly in the socket.
• Reset appliance: Leave the freezer unplugged for 5–10 minutes, then reconnect directly to a wall outlet and see if E6 clears.

When to call a technician: If the error persists with a known-good outlet and cord, the internal power supply on the main PCB may be failing and should be serviced by a professional.
