Hello, my first question would be, does it actually drain the water out, or does it leave water in the bottom of the tub? if it leaves water, there is a restriction in the drain system; if not you may have a stuck relay on the control board.

KitchenAid Dishwasher will drain when I put water in it but it keep trying to drain till code E1F9 shows

No there is no water remaining in the bottom even under the sump drain area as I cleaned that to be sure there wasn’t something beyond the screen

That sounds like a control board issue.
