Dryer will not start; the display is on, but pressing Start does nothing.

Safety first: If you need to open panels, unplug the dryer first.

Basic checks:

• Ensure the door is firmly closed and that nothing is trapped in the door seal.
• Check the display for a child lock symbol; if present, disable the lock according to the user manual (often by holding a specific button combination).
• Try selecting a different program and pressing Start again.
• If the dryer still does not start, test the door switch for proper operation and replace if faulty.
• If the Start button does not register (no beep or response), the user interface board may be defective and require replacement.
