What the F:34 error code actually means

Your Bosch washer is unable to lock the door, so it has stopped to prevent the door from opening during a wash or spin cycle. This could be because the door latch is broken, the door is not closing all the way, or the rubber seal around the door has become stiff and is blocking a proper close. You will need to inspect the door and latch before running another cycle.

Questions people ask about F:34

What does F:34 mean on a Bosch washer?
F:34 means the washer attempted to lock the door but could not confirm that the lock engaged successfully. The machine will not start a cycle until this condition is resolved. The cause can be a failed door lock assembly, a damaged door hook, a stiff gasket, or a wiring issue.
Will resetting the washer clear the F:34 error?
Turning the washer off and back on will clear the displayed error temporarily, but if the underlying cause has not been addressed, the code will return as soon as the machine attempts to lock the door again. A reset is only a useful first step to rule out a one-time glitch, not a permanent fix.
How much does it cost to repair the F:34 error on a Bosch washer?
If only the door lock assembly needs replacement, parts typically range from $30 to $80 depending on the specific model, and a technician visit to diagnose and replace the part often brings the total to $100 to $250. If the door hook or gasket is the culprit, parts costs are generally lower, though labor rates vary by region.
Can I fix the F:34 error myself?
Some causes of F:34 are DIY-friendly. Start by powering the washer off and back on to reset the fault, then inspect the door hook, gasket, and door alignment. If the door lock assembly itself has failed, replacing it requires disconnecting the harness and removing the front panel or door boot, which is a moderate-difficulty repair that many experienced DIYers can complete.
Is it safe to use my Bosch washer while it shows F:34?
No. The washer displays F:34 and refuses to run precisely because it cannot confirm the door is securely locked. Running a washer with an unconfirmed door lock creates a risk of the door opening during a spin cycle, which could cause water damage or injury. Do not attempt to bypass this fault.
