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

Safety first: Ensure hands are dry when operating the control panel.

Step-by-step checks:

• Confirm door closure: Close the door firmly until you hear a click. Try gently lifting the door while pressing Start to see if a misaligned latch is the issue.
• Child lock: Check the user manual for the child lock combination (often holding two buttons for several seconds). Disable the lock and try again.
• Cycle selection: Make sure a wash program is selected before pressing Start.
• Door latch inspection: If the unit beeps and shows a door icon, the latch switch may be faulty and should be replaced.

Warning: Do not tape or bypass the door switch; this is a serious safety hazard.
