A:Answer Hi 062063110367. Thank you for your question. It seems that the Child Lock may be activated. Here are the instructions for that feature. Child Lock NOTE; Only front-control models have Child Lock. 1.After starting a cycle you can activate the Child Lock. 2.Press and hold the C button until the display reads “CL” (models with display) or the “Child Lock” LED illuminates (models without display). NOTE: “CL” disappears from screen when button is released. 3.Child Lock is now active and buttons will not function, except On/Off. 4.To deactivate, press and hold the C button until the “Child Lock” LED turns off or “CL” disappears from the display. If this does not unlock the dishwasher, please contact our Customer Support Team at 1-800-944-2904.
