Washer-dryer shows E15 and may not start; often associated with incorrect mains voltage or power issues.

Safety: Always unplug the appliance before inspecting electrical components. Do not work on live circuits.

• Check outlet: Test the wall socket with another appliance to confirm correct voltage and stable supply.
• Inspect power cord: Examine the Belling washer-dryer power cord for cuts, burns, or kinks. Replace if damaged.
• Interference filter: Access the mains filter (usually near the cord entry). Check for signs of burning or bulging. If suspect, replace the mains interference filter with a compatible Belling part.
• PCB power section: If the machine intermittently powers off or shows E15 despite a good supply, the low-voltage power supply on the main PCB may be failing. This requires PCB replacement by a technician.
• Do not bypass safety: Never bypass the mains filter or earth connections; this is dangerous and voids safety compliance.
