The dishwasher powers on but will not start a cycle; the Start button blinks or nothing happens when pressed.

Safety First: Turn off power before accessing the latch or control panel.

• Check door closure: Ensure the door is firmly closed and latched. Listen for a solid click.
• Disable control lock: On many Whirlpool models, press and hold the Control Lock or Heated Dry button for 3–5 seconds to unlock the controls.
• Reset control: Turn off power at the breaker for 5 minutes, then restore and try again.
• Inspect latch: If the problem persists, access the door latch and test the switch for continuity when closed. Replace the latch assembly if faulty.
