Bosch Washer Error Code 35

Error code 35 on a Bosch washer indicates that the door lock mechanism has failed to release, preventing the door from being unlocked at the end of a cycle. The door lock system on Bosch washers uses an electromechanical latch assembly that receives a signal from the control board to engage and disengage at the appropriate points in the wash cycle. When the control board sends an unlock command but does not receive confirmation that the lock has released, error code 35 is triggered. This is a safety-focused fault that keeps the machine from resuming operation until the door lock condition is resolved.

The root cause can be mechanical or electrical. On the mechanical side, the door hook or strike plate may be physically stuck or misaligned, preventing the latch from retracting. A stiff or swollen door gasket can press against the door with enough force that the latch cannot release even when electrically commanded to do so. On the electrical side, a faulty door lock actuator may fail to physically move the locking pin, or a damaged wire harness between the lock assembly and the control board may prevent the unlock signal from being transmitted or confirmed correctly.

Diagnosing this fault begins with a power reset by turning the machine off and then back on, which clears the error and re-sends the unlock command. If the door remains locked or the error returns, the door lock assembly itself should be inspected for mechanical binding or electrical failure. The wire harness connectors at the lock assembly should be checked for corrosion, loose pins, or visible damage. The door hinge alignment, gasket condition, and door hook engagement should also be evaluated to rule out mechanical interference.
