Dishwasher powers on but will not start cycle when Start is pressed.

Safety First: Disconnect power before testing switches.

Steps:

• Check control lock: On many Maytag models, press and hold the Control Lock or Heated Dry button for 3–5 seconds to toggle the lock off.
• Ensure proper closure: Push racks fully in and remove any items blocking the door. Close firmly until you hear a click.
• Test door latch: If the control shows door open or will not start, test the door latch switch for continuity when closed. Replace the latch assembly if defective.
• UI test: Enter diagnostic mode (per tech sheet) to test the Start key. If unresponsive, the user interface panel may need replacement.
