Zanussi dryer powers on but will not start the cycle when the start button is pressed.

Safety first: Disconnect from mains before accessing the control panel or door lock.

• 1. Check display indicators: Look for a key or padlock symbol indicating child lock. Disable child lock according to the user manual (often by holding two buttons for several seconds).
• 2. Confirm door closure: Open and firmly close the door. Listen for the latch click. If the door feels loose, inspect and replace the door catch if necessary.
• 3. Test start button: Press the start/pause button firmly. If it feels stuck or does not click, the button or UI board may be faulty.
• 4. Power reset: Unplug the dryer for 5 minutes, then reconnect and try again. This can clear minor logic faults.
• 5. Internal checks (advanced): Access the control panel and test the start button switch for continuity when pressed. Replace the user interface board if the switch is defective.
• 6. If still not starting: The main control board may not be receiving the start signal or may have a relay fault. Professional diagnosis is recommended.
