The F29 code means your washer cannot securely lock the door to begin a cycle. This is usually caused by a physical obstruction, a faulty door lock assembly, or a communication break between the latch and the main control board.
When I see F29 on a Kenmore display, I immediately check the physical latch for lint buildup or cracked plastic. This error triggers when the CCU sends power to the door lock solenoid but never gets the return signal confirming the door's secure. It's usually a mechanical failure of the latch itself, but a loose wire harness or a failing control board relay can also prevent the lock from engaging. Don't ignore it, the washer won't run at all until it's fixed.
Nine times out of ten, F29 points directly to a failed door lock assembly that needs replacing. Before you buy parts though, make sure the door is closing flush against the cabinet. If the strike is misaligned by even a fraction of an inch, the locking pin won't seat correctly and the board throws this error. I replaced three of these on Kenmore Elites just last week, so yeah, it's a pretty common fix.

Symptoms You May Notice
The washer clicks three times near the door when you press Start, then just sits there doing nothing.
F29 flashing on the display about 60 seconds after you start a cycle.
Door stays completely unlocked and loose even after you've pressed Start and waited.
At the end of a finished cycle, the door locks up and won't open even after you press the door release button.
You can hear the solenoid buzzing or humming near the latch area but the door never actually locks.
Can you reset a Kenmore washer to clear the F29 code?
To clear a ghost F29, unplug the washer completely and leave it unplugged for at least three full minutes so the CCU capacitors discharge. Plug it back in, close the door firmly, and press Start. If the code comes back within the first 60 seconds right when the door tries to lock, the hardware problem is still there and a reset won't fix it. But if the error was from a power glitch, this clears it about half the time.

Frequently Asked Questions
Can I bypass the door lock on a Kenmore washer?
Don't try it. These front-loaders aren't wired like old top-loaders where you could jumper two wires and call it a day. The CCU actually measures the resistance state and switch position of the latch during the lock sequence. If it doesn't see exactly what it's expecting, it kills power to the motor and throws the error. Some people try jumping the switch leads to fool it and occasionally it works short-term, but you're running a machine with 50 pounds of water spinning at 1000 RPM with no door interlock. That's a bad bet.
Why does the F29 code appear at the very end of a cycle?
That's a different failure mode. If it's showing up at the end, the door locked fine at the start but now won't release. The CCU sent the signal to unlock the solenoid but the pin stayed stuck. Usually that's a mechanical jam inside the latch, or the solenoid is stuck energized. Try unplugging the machine for 10 minutes, which lets the solenoid de-energize and sometimes releases the door. If it's happening every single cycle, replace the latch. And don't force the door open or you'll crack the strike right off.
How much does it cost to fix an F29 error?
DIY, you're looking at $60 to $120 for the door lock assembly depending on your specific model. The part on the 796-series machines runs a bit cheaper than the older 110-series. Figure an hour of your time to swap it. If you call a tech, expect $200 to $300 total including the service call and labor. Honestly if your machine is more than 10 years old and already has other stuff going wrong, think hard about whether a $250 repair makes sense before you commit.
Can a dirty door seal cause an F29 code?
Yeah, and it's a sneaky one. If the rubber bellows is caked with detergent buildup or mold, it can actually hold the door slightly open, like a millimeter or two, which is enough to keep the strike from fully engaging the latch sensor. Clean the bellows with a rag and some white vinegar, dry it off, and try closing the door again. Sometimes you'll hear it latch way more firmly after a good cleaning. Not the most common cause but I've seen it a handful of times, especially on machines where people use too much detergent in a low-HE machine.
Will F29 go away on its own or do I need to actually fix it?
It won't go away on its own. If the latch is broken, it's broken. Now, occasionally F29 is triggered by a one-time glitch like a power surge, and unplugging for a few minutes clears it. If it comes back, you've got a real hardware problem. Don't keep force-starting the machine by unplugging and replugging it over and over either, because that puts unnecessary stress on the CCU. The parts are affordable and the repair's pretty doable for an intermediate DIYer with a multimeter and a couple hours.
