Safety first: Disconnect power before removing door panels.

1. Confirm door closure: Close the door firmly until you hear a click. Ensure racks or tall dishes are not preventing full closure.
2. Check for child lock: Many Insignia dishwashers have a control lock feature. Look for a lock icon on the display and hold the designated button combination (refer to user manual) for several seconds to unlock.
3. Test different cycles: Try starting a different cycle to rule out a specific program issue.
4. Inspect door latch: Remove the inner door panel and test the latch switch for continuity when the latch is engaged. Replace the door lock assembly if the switch is faulty.
5. Evaluate UI panel: If the Start button does not register but other buttons work, the touch control panel may need replacement.

If the dishwasher still will not start after these checks, the main control board may require professional diagnosis.

Dishwasher powers on but will not start a cycle; pressing Start does nothing or only beeps.
