THE PLASTIC FACE COVER OF THE LOCK MECHANISM HAS SHATTERED AND THE CONTACT SWITCH ON THE INSIDE HAS ALSO BECOME DETACHED FROM THE BODY OF THE MACHINE. HOW DO I REPAIR THIS MECHANISM AND /OR WHERE CAN I OBTAIN ANY TECHNICAL DRAWINGS TO VIEW THE ASSEMBLY MECHANISM TO SEE HOW IT APPEARS IN A WORKING CONDITION. I NEED TO KNOW IF THE CONTACT MECHANISM OR ANY OTHER PARTS OTHER THAN THE PLASTIC FACE COVER ARE REQUIRED. ANY ADVICE WOULD BE WELCOMED. THANK YOU
