Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.
Is the light blinking seven times and then repeating?
okay , I want you to try a board reset follow these instructions and tell me if the dishwasher resets,
press "Heated dry, high temp wash, heated dry, high temp wash, heated dry, high temp wash" All the lights will flash at which point you can press cancel to reset the board. If the error comes back then replace the element, the only other possibility is the board itself is bad.if you don't have a heated dry button use air dry or energy saver dry
