Bush dryer powers on but will not start when you press the start button; it may beep or show a padlock symbol.

Safety first: For control checks, you can leave the dryer plugged in but do not remove covers. For internal checks, unplug first.

• Check for child lock: If a padlock icon is shown, disable child lock according to the user manual (often by holding two buttons for several seconds).
• Ensure door is fully closed: Open and firmly close the door. Listen for a positive click from the latch.
• Test start button: Try pressing the start button firmly. If it feels loose or unresponsive, the control panel may be faulty.
• Door switch test: Unplug the dryer, access the door switch behind the front panel, and test continuity while operating it. Replace if faulty.
