Bosch Dishwasher Error Code Er:02

Er:02 means the dishwasher's door lock cannot be released. The control board sent a signal to unlock the door latch but did not receive confirmation that the latch returned to the open position. This can be caused by a failed lock actuator, a wiring harness problem, or a mechanical obstruction. The dishwasher will not resume normal operation until the fault is resolved.

No, you should not attempt to run a wash cycle while Er:02 is active. The dishwasher will not operate correctly with a door lock fault, and forcing operation could result in the door opening mid-cycle. Address the fault before running the appliance again.

Repair costs depend on the root cause. If only a wiring connector needs to be reseated, there may be no parts cost at all. Replacing the door lock assembly typically costs between $80 and $200 for the part, plus labor if a technician performs the repair. Control board replacement, if needed in rare cases, can range from $150 to $400 or more for parts alone.

Some causes of Er:02 are DIY-accessible, such as inspecting and reseating the wire harness connectors or clearing a physical obstruction from the latch area. If the door lock actuator or internal position sensor has failed, replacing the door lock assembly is a moderate repair that requires disconnecting power and accessing the inner door panel. If you are not comfortable working with appliance wiring, a qualified technician should handle the repair.

A power reset by unplugging the unit or switching off the circuit breaker for a few minutes may temporarily clear the error code, but it will return if the underlying problem with the door lock is not fixed. A reset alone does not repair a failed actuator, broken wire, or mechanical obstruction.
