Dryer shows E09 and will not start; sometimes appears after a power cut or surge.

Safety first: Turn off the circuit breaker and unplug the dryer before opening any covers.

Step-by-step checks:

• Verify supply: Ensure the dryer is connected to the correct voltage supply as specified on the rating plate (typically 220–240V AC). Avoid extension leads or multi-way adapters.
• Inspect mains cable and plug: Check for signs of overheating, discoloration, or damage at the plug and cable entry.
• Check terminal block: Remove the rear cover over the mains terminal block. Confirm all screws are tight and there are no burnt terminals.
• Inspect line filter: Locate the mains interference filter (usually near the cable entry). Look for bulging capacitors or burn marks. Replace if visibly damaged.
• Power reset: After checks, reconnect and try a different wall socket if possible.

When to call a technician: Persistent E09 with correct supply may indicate a damaged power supply section on the main control PCB.
