Bosch Washer Error Code 35

Error code 35 on a Bosch washer means the door lock could not be unlocked after the machine attempted to release it. The control board sent an unlock command but did not receive confirmation that the door lock released successfully. This can be caused by a broken door lock assembly, a stuck door hook, a stiff gasket creating door pressure, or a wiring fault in the harness connecting the lock to the control board.

You should not continue using the washer until the error is resolved. A malfunctioning door lock is a safety concern because the door interlock is designed to prevent the machine from operating with an unsecured door. Running the machine with a faulty lock mechanism could lead to water leaks or further component damage.

Repair costs depend on the root cause. If only a wire harness connector needs reseating or cleaning, the cost may be minimal. Replacing a door lock assembly typically involves parts costs in the range of $30 to $100 or more depending on the model, plus labor if a technician is used. A full service call from a repair technician generally ranges from $100 to $250 or more depending on your location and the extent of the repair needed.

Start by turning the washer off and then back on to reset the error and re-trigger the unlock command. If the door opens, inspect the door hook, gasket, and latch area for any obvious mechanical issues before running another cycle. If the door remains locked or the error returns, check the wire harness connectors at the door lock assembly for damage, and test or replace the door lock assembly if it shows signs of electrical or mechanical failure.

A power reset by turning the machine off and then on again may clear the error temporarily if the lock releases on the second attempt. However, if the underlying cause is a failed door lock assembly, stuck door hook, or damaged wire harness, the error will return. A reset is a valid first diagnostic step but is not a permanent fix if a component has failed.
