Auto-start or auto-off timer functions do not work correctly

Safety: No internal work is required for basic checks.

• Verify settings:
  • Check the user manual and ensure auto-start and auto-off are enabled and set correctly.
  • Confirm the clock time is accurate.
• Reset machine: Perform a factory reset if your model supports it to clear any corrupted settings.
• Stable power: Avoid unplugging the machine frequently; use the power button instead.
• Repair: If timer functions still fail, the main control board may need replacement.
