Why does the LOCK ON light keep blinking on my Kenmore Ultra Wash Dishwasher Model 665.15779?

Kenmore Ultra Wash Dishwasher Model 665.15779 LOCK ON light blinking on control panel, unable to use washer. If buttons were locked, LOCK ON light should be lit continually not flashing. If you press and hold NO HEAT DRY button to disengage lock, nothing happens. If you press the CANCEL button it begins to blink in unison with the LOCK ON light. How can I stop the light from blinking to allow button function again?

Can you explain how this works? My washer is the Kenmore 655 Ultra. I took the control panel apart today. Behind the lock light is simply a ribbon and it's not even that close to the outside "button". It doesn't make sense how the nail trick would do anything. I'm desperate so I may try it, but I'd love to understand. Thanks!

I tried everything to fix the blinking lock light and nothing worked. Took a nail to the light gently while the breaker was turned off. Reset breaker and boom dishwasher is good as new. Killing that light must bypass an error on the board and allow it to function properly. I will continue to use my dishwasher at no cost to me until another part of it fails! It has served me well for 15 years and will continue to do so thanks to Robert Briggs!

Sounds crazy, but I had this exact problem and used a small drill bit to disable the "Lock On" light. I pressed Cancel for 5 seconds, the diswasher started working again. Make sure to turn off the breaker before drilling the light.

This works! Hard to believe. Thank you Robert Briggs. I used a nail and my dishwasher works now! I can see that a drill would work too. My dishwasher stops and starts sometimes though; still washing dishes 3 weeks later.

One of my buttons must have been stuck. I unplugged it and took it apart to try and fix it but couldn't figure out how to take out the buttons. I ran my fingers against the buttons to see if they would just unstick. Not sure if I did anything but, after I put it back together and plugged it back in bam it worked.

My Kenmore Elite Microclean Dishwasher Model 665.1476 was about 5 years old in 2018 when the LOCK light started blinking on the control panel and I was unable to use the washer. As suggested a post, I tried pressing and holding the TOP RACK ONLY button to no avail. I tried pressing that plus the START button with same non-result. I opened and closed the door with same non-result. My dishwasher does not have some of the buttons suggested in other posts. Finally, I disconnected electrical power from the dishwasher by shutting off the breaker. After longer than 5 minutes, I turned the breaker back on; light still flashing. By trial and error, I pressed the SMART DRY PLUS button and held it more than 5 seconds; the control panel displayed a countdown from 3 seconds and the lock light went out. Then the dishwasher worked!

I know this thread is old but could you please explain to me the nail thing. I have a kenmore ultra wash quietguard plus. The lock on will not stop blinking and I've seen the nail technique in other forums as well but it hasn't been explained well. Thank you in advance!!!

Yes, the nail worked. Found out the new control panel would cost over $400.00. Ordered a new dishwasher, finally found a hammer and figured nothing to lose. Dishwasher is running perfectly

If it's a Kenmore Elite try holding the sani-rinse button for 3 seconds. Worked for us.
