Hello, the blinking lights at the normal and cancel buttons indicate a shorted keypad. It is like you are trying to press 2 buttons at the same time, and the control does not know what to do, and it shuts down and starts blinking. The keypad will need to be replaced. Here is the part number for the interface: WP8531262 User Interface (Full-Door Console) | Genuine Whirlpool OEM In Stock

That’s quite an expensive part. Machine is like 23 years old. Debating whether to replace parts or just get a new machine.
