Washer-dryer combo displays E10 and will not start; control panel appears unresponsive or partially functional.

Safety first: Disconnect power before removing any control panels or boards.

• Power reset: Turn the unit off at the wall for 5 minutes, then restore power. This can clear transient communication faults.
• Check outlet and supply: Verify the wall outlet has correct voltage and is not shared with heavy loads that may cause voltage drops.
• Inspect control connections: Remove the top cover and control panel fascia. Check that all wiring harnesses between the user interface and main control board are fully seated and free of corrosion or damage.
• Look for board damage: Examine the Fisher & Paykel main PCB for burnt components, bulging capacitors, or signs of moisture ingress.
• Board replacement: If visible damage is present or E10 persists after reseating connectors, replace the main control board with the exact Fisher & Paykel part number. Transfer any configuration jumpers as per service documentation.
• Professional service: Because miswiring can cause further damage, board-level repairs are best performed by a qualified technician.
