Bosch washing machine door lock accidentally triggered with the door open – how I reset it
I’m posting this in case someone runs into the same problem.
On my Bosch washing machine, the door-lock mechanism was accidentally pushed into the locked position with a screwdriver while the washing machine door was open. Once this happens, the door can no longer be closed because the mechanical latch inside the door-lock assembly is already in the “door closed” position.
I tried to reset the mechanism from the outside, but in my case there was no way to release it with a screwdriver or by operating the normal emergency door release.
The solution was to remove the door-lock assembly and disassemble it.
The electrical part of the lock can be unclipped from the housing. The mechanical part can also be unclipped, although the plastic clips are quite tight and require some careful force.
Once the mechanical section is separated, the internal locking mechanism becomes accessible and can be manually returned to its normal/open position.
After resetting the mechanism and clipping the lock assembly back together, the door could be closed normally again and the lock worked as before.
So, at least with this Bosch lock design, if the latch has been manually triggered with the door open and cannot be released from outside, simply pulling the emergency release or manipulating the latch from the front may not be enough. The mechanical part of the door-lock assembly has to be opened and the mechanism manually reset.
Obviously, disconnect the washing machine from the mains before removing or opening the door-lock assembly.
I hope this saves someone else some time, because it took quite a bit of trial and error to figure out that the mechanical section itself could be unclipped and reset.

Thanks for posting this — that is a very useful tip and it makes sense for this Bosch lock design.
For anyone else with the same fault on a Bosch WAYH2840/09 or similar model, the key point seems to be:
1. If the door lock has been accidentally tripped with the door open, the machine may think the door latch is already engaged. 2. In that state, the door often will not shut properly because the lock’s mechanical catch is sitting in the “closed/locked” position. 3. The usual external methods may not work: - carefully trying to move the latch back from the front - using the normal emergency door release 4. If it will not reset externally, the next step is to remove the door-lock assembly and inspect it. 5. On this style of Bosch lock, the electrical section can be unclipped from the housing, and the mechanical section can also be unclipped to access the jammed latch mechanism. 6. Once opened, the internal catch can be manually returned to the normal open position, then the lock can be reassembled and refitted.
Important safety reminder: always isolate the appliance from the mains before removing panels or inspecting the door-lock assembly. If anyone is not confident dismantling the lock, or if there is any damage to the wiring, fitting, or interlock, it is best to use a qualified appliance engineer. Any mains, gas, or sealed refrigeration work should always be left to a properly qualified engineer.
