Bosch Washing Machine Error Codes

Bosch washer error codes for drain, fill, door lock, motor, and control faults.

Use this Bosch washer hub when the display points to water fill, draining, door lock, motor, or control faults. Common code guides cover the shared Bosch washer path; model hubs narrow the guidance when exact model coverage exists.

If the machine has standing water, a locked door, or repeated trips at the outlet, read the safety notes on the code page before opening panels or retrying a cycle.

What it means

A Bosch washing machine code points to the system the control board could not complete, such as fill, drain, heat, door latch, sensor, or motor operation.

Common causes and symptoms

Common causes include blocked filters, restricted hoses, failed sensors, wiring faults, or control-board errors. Symptoms often include beeping, stopped cycles, standing water, poor drying, or a locked door.

What to try first

Turn power off before inspection, check the visible filter or hose path, confirm the door closes fully, then open the matching code guide for model-specific fixes and safety notes.
