Frequently Asked Questions

My Whirlpool dishwasher Start light blinks after I press Start - is it broken?
No. The blinking Start light after you press Start is normal on many models - it blinks while the dishwasher waits for the door to fully latch before beginning the cycle. Once the door microswitch detects a proper close, the cycle begins and the light stops blinking.
