Kenmore Dishwasher Won't Start: Door Latch and Power
Quick Answer
Kenmore dishwasher won't start: push door firmly until latch clicks. Check Control Lock (hold lock button 3 sec). Check Delay Start not accidentally set.
Most of the time when I show up to a Kenmore that won't start, it's something stupid simple, like the Control Lock got bumped on accident. But ignore it and you're hand-washing dishes for a week waiting on parts. The thermal fuse is the sneaky one. It blows quiet, no warning, and suddenly the whole machine is completely dead. Don't blow this off.
Kenmore Dishwasher Won't Start: Door Latch and Power
When your Kenmore won't respond, the display is your first clue. Lights on but nothing happening? We're dealing with a latch or lock issue. Totally dark? That's a power problem, probably a blown thermal fuse or a tripped breaker. Kenmore shares most of its guts with Whirlpool, so parts are cheap and everywhere. I've fixed this same issue on probably 50 different Kenmore models and it's almost never as complicated as it looks.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Door latch incomplete30%
Control/Delay Lock20%
Water supply off15%
Touchpad failed15%
Thermal fuse blown10%
Float switch stuck up10%
Symptoms You May Notice
You push Start and absolutely nothing happens, no sound, no water, not even a click from the latch area.
The display shows a padlock icon or the letters CL and none of the buttons do anything no matter how many times you press them.
The whole machine is completely dark, no lights on the panel at all, like it's not getting any power.
The dishwasher shows a countdown timer on the display but never actually begins filling with water.
The door clicks shut fine but the Start button just beeps back at you without beginning a cycle.
Can you reset a Kenmore dishwasher to clear the WONT-START code?
Go to your breaker box and flip the dishwasher circuit off for 5 full minutes. Not 30 seconds, five actual minutes. The capacitors on the control board need time to fully discharge. Flip it back on. On most Kenmore models you can also try pressing Heated Dry, Normal, Heated Dry, Normal in quick succession with the door latched closed. That triggers diagnostic mode and can clear a stuck error state.

Frequently Asked Questions
How much does it cost to fix a Kenmore dishwasher that won't start?
Depends on what's actually broken. Door latch is $15-$30 in parts and you can do it yourself in 20 minutes. Thermal fuse runs about $12. If you're calling a tech, expect $150-$250 for either of those repairs including the service fee. Control board is where it gets painful. The part alone is $150-$300, and with labor you're looking at $350-$450 total. At that point I usually tell people to price out a new dishwasher before committing.
Can I fix this myself or do I need to call a pro?
Honestly, latch and fuse repairs are totally doable yourself. You need a Torx T15 screwdriver and a multimeter, that's the whole toolkit. The hardest part is getting the inner door panel off without snapping the plastic clips. Just go slow and don't pry hard. The whole job takes maybe 30-45 minutes your first time through it. If the control board is dead, I'd still try DIY since the part is expensive either way and the labor isn't complicated.
Is my Kenmore dishwasher worth repairing?
If it's under 10 years old, almost always yes. The 665-prefix Kenmore models are basically Whirlpool machines and they're built solid. I've got customers still running 14-year-old 665-series units. If the repair is under $200, fix it. If you're staring at a failed control board on a 12-year-old machine, that's when I'd start shopping. A decent replacement dishwasher runs $400-$600, so do the math on what the repair actually costs you.
Why did my Kenmore dishwasher stop working with zero warning?
Thermal fuse, most likely. It's designed to blow without warning as a safety feature. One cycle it's totally fine, next time you push Start and there's nothing. No error code, no beeping, just dead. It usually means the machine overheated at some point, either from a blocked drain, a wash motor running hot, or just years of heat cycles. Replace the fuse, but also figure out why it overheated or you'll blow the next one too.
What exactly is Control Lock and how do I turn it off?
Control Lock is basically a child lock for the panel. Every button gets disabled and nothing works. It's a great feature until you activate it by accident leaning against the counter. Most Kenmore dishwashers turn it on by holding the Lock button or No Heat Dry for 3 seconds. The display shows a padlock or CL. To turn it off, do the exact same thing. Hold that button for 3 full seconds. If the padlock icon disappears, you're good to go.
My Kenmore dishwasher has power but won't start a cycle. What's going on?
If the lights are on but nothing runs, I'd bet on the door latch first. The control board needs a signal from the door microswitch that it's safe to fill with water. No signal, no cycle. Give the door a firm push and listen for a click. No click means the latch isn't engaging. Second thing to check is whether one of the buttons on the touchpad has failed, which is way more common on older machines. If only certain buttons don't work, that's usually the membrane going bad from steam exposure.
