Washer-dryer stops mid-cycle with E09; drum may be full of water and door locked

Safety first: Disconnect from mains before removing the control panel or PCB housing.

• Power reset: Leave the appliance unplugged for at least 5–10 minutes to allow capacitors to discharge, then reconnect and try a short cycle. If E09 returns immediately, proceed with inspection.
• Inspect PCB connections: Remove the control panel or side panel to access the main control PCB. Check all multi-pin connectors for secure fit and signs of overheating or corrosion. Reseat each connector one at a time.
• Visual PCB inspection: Look for burnt components, bulging capacitors, or cracked solder joints, especially in the power supply section (near mains input). Any visible damage usually means the PCB must be replaced.
• Check for external shorts: Inspect wiring looms for crushed or pinched sections that could short to the chassis, particularly around the door area and base.
• Professional service: Because E09 typically indicates an internal PCB failure, replacement by a Rangemaster-qualified technician is recommended. Component-level repair is not generally supported for consumers.
