You haven't said why it needs reset, so possibly it can't be reset if there is a mechanical or electrical problem with a part in the dishwasher.
Here is a link to a page on YouTube. They usually have good repair videos and how to videos:

You can also reset the breaker that supplies power to it and see if that helps. This sounds like the control panel is going out.

Have you unplugged wait for 15 sec plug back in. Might reboot.

Similar Kenmore Dishwasher 665.18664000. Time saver and Quick rinse were the only programs that would run. I pressed "high temp scrub" then "air dry" then "high temp scrub" then "air dry" and the machine went into a diagnostic mode and counted down from 10 while running a series of tests. After about 10 minutes and various test cycles the machine reset and the "normal wash" light had come back on. If this doesn't work then you may have a problem with the controller which other threads have mentioned replacing yourself for about $120.

Open and close the door to make sure the door latch is securely fastened

Hi-Temp Wash, Hi-Temp Rinse, or Sanitize options.
Some models have options that may require a water heating delay, such as Hi-Temp Wash, Hi-Temp Rinse, or Sanitize. Additional time may be required to heat the water to the proper temperature. The dishwasher will continue to circulate water during this heating delay but the timer will not advance until the proper temperature is reached

unplug the unit from power and plug it in back after may be minute or so.if it works, fine otherwise control panel has to be chgd.it comes as complete assly(top black part) and it is very easy to chg.

Try holding down the "lock" button.It may be the way to unlock the problem.

you'll need to enter a diagnostic mode, press in this order, hi-temp(sani-rinse)----heated dry--hitemp---heated dry... all lights should light, close door and let cycle for about a min, after press the cancelbutton, you should be good to go, the buttons on your model may read slighty different names, if this "toggle of buttons" does not work, you can remove thelower access panel and htere willl be a tech sheet/trouble shoooter behind the panel, in there it will explain how to enter diag/test mode

I had the same flashing light problem first the normal wash flashing light then the others. I tried shuting of the breakers but nothing. I tried resetting the panel by pushing normal wash and heated dry simultaneously and nothing. So I took the six screws holding the front panel out and unplugged the ribbon type wires and plug and unplugged it several times to help make a better contact and I was able to get it to work right away. This may not work for all but I worked for me. It is very easy to do and it's worth a try if you're having the same problem. It took me less then 10 minutes.

Some of these units have a thermal fuse in line with and mounted on the control card. This will need to be checked. Also check the door switches. Some models will aloow power to the control card but to nothing else.
