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

Safety first: Do not force the door closed; this can damage the latch.

• Verify door closure: Ensure racks are fully pushed in and no tall items are blocking the door. Close firmly until you hear the latch click.
• Check for control lock: Many Dacor dishwashers have a control lock feature. Look for a lock icon on the display and hold the designated key combination (often 3–5 seconds) to unlock.
• Try a different cycle: Select another cycle and press Start to rule out a specific program glitch.
• Inspect door latch: If the unit beeps and shows a door-related message, the latch switch may not be closing. Replace the Dacor door latch assembly if worn or broken.
• UI button test: If only the Start button is unresponsive while others work, the UI board may be failing and require replacement.
