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

Safety first: Ensure the dishwasher is idle before changing settings.

• Confirm door closure: Push the door firmly until you hear a click. Check that racks or tall items are not blocking closure.
• Disable child lock: Hold the lock key (or designated button) for 3–5 seconds to unlock the controls.
• Check for error lights: Some models flash a door icon if the latch is not detected. If so, inspect and possibly replace the Midea door lock assembly.
• Control panel test: If some buttons do not respond, the touch panel may be faulty and require replacement.
