Sanitize Blinking Light
Some Kenmore dishwashers have a sanitize feature; when this light blinks, it means the sanitization step failed because the hot water in the dishwasher did not achieve the desired temperature or the final rinse cycle was interrupted.

The buttons must be pressed in the following order: "Heated Dry," "Normal Wash," "Heated Dry" and "Normal Wash." After pressing the buttons, your Kenmore dishwasher will begin a short, 12 minute test cycle and reset the control panel. https://removeandreplace.com/2015/10/26/kenmore-dishwasher-error-fault-codes-led-display-blinking

The contact on the end off the cycle in the switch is bad you try to clean it or replace the main switch,all the best.

The easiest way to confirm if the arms are blocked is by turning all the arms in the machine to a certain same position and running the machine for a few minutes in its wash cycle. Open the door and see if the arms have moved. If not, check all the holes in the arms for blockages. Sometimes its very difficult to clean them. You may have to poke a pin or something into hole and then shake the obstruction out through the large inlet hole under the spray arm itself.

I think you have blocked pipe which probably linked with your sink pipe, make sure you open the pipe and clean it with hot water and watch if the dishwasher working normally and pull the water outside, if this is the case then it is defiantly will be sorted and it is bloked and easy task, I hope this advice will help
