Possible Causes

Door not fully closed, Faulty door latch switch, Stuck Start button, Control lock (child lock) enabled

How to Fix / Troubleshooting

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.
