Whirlpool Quiet Partner III lights won't turn off

Last night none of the lights would turn on my dishwasher and the machine wouldn’t start. After research I did a rest. Now all the lights are on and won’t turn off. I tried resetting but it doesn’t do anything. If I hold down the heater dry button for 15-20 seconds all the lights will turn off but as soon as I let go they come back on. Any suggestions?
