Error code E13 is displayed and the refrigerator may intermittently shut down or reboot.

Safety first: Always unplug the refrigerator before inspecting internal wiring or the control board. If you suspect a household wiring issue, contact an electrician.

Steps:

• 1. Check wall outlet: Plug another appliance into the same outlet to confirm stable power. Avoid using extension cords or multi-plug adapters.
• 2. Inspect mains cord: Examine the refrigerator power cord for cuts, burns, or kinks. Replace if damaged.
• 3. Access main PCB: Remove the rear cover to expose the control board. Check that the mains input connector is firmly seated and that there are no signs of overheating.
• 4. Visual inspection: Look for burnt components or bulging capacitors in the power supply section of the PCB.
• 5. Replace control board if needed: If the board shows clear signs of power supply failure or E13 persists despite stable mains and good wiring, replace the main control board with the correct Fagor module.
• 6. Monitor operation: After replacement, observe the refrigerator for several hours to ensure it no longer shuts down or reboots and that E13 does not reappear.
