Washer-dryer displays E15 and will not start; may occur after a power surge or outage.

Safety first: Disconnect the appliance from mains before accessing any electronic components.

• Step 1 – Power cycle: Unplug the washer-dryer for at least 15 minutes, then reconnect and attempt to start a basic cycle.
• Step 2 – Check supply voltage: Ensure the wall socket provides stable voltage and that there are no loose plugs or extension leads causing intermittent power.
• Step 3 – Inspect PCB (advanced): Remove the top cover and locate the main control board. Look for obvious damage such as burnt tracks, bulging capacitors, or scorch marks.
• Step 4 – Wiring check: Verify that all connectors to the PCB are fully seated and that there are no signs of overheating at the terminals.
• Step 5 – Surge protection: If E15 occurred after a lightning strike or surge, consider using a surge-protected outlet in future.
• Step 6 – PCB replacement: In most cases, E15 indicates a failed main PCB. Replacement should be carried out by a qualified technician, as the board must be correctly configured for your specific Caple washer-dryer model.
