Kenmore Frontload washer code d.o.

My sears Kenmore washer is displaying a code DO and consequently not turning on.
I do not have a service manual and I search the code and nothing comes up does anyone have any idea what this code mean. Or does anyone have the service manual or a link to a service manual for this washer

Thank you
