Carefully remove the drive belt from the motor and drum pulleys. Then, disconnect the motor's wiring harness and unbolt the motor from the washing machine tub to remove it completely.With the motor removed, locate the two carbon brushes.

Re-bolt it to the tub, reconnect the wiring harness, and carefully loop the drive belt back onto the motor and drum pulleys.Turn the appliance off, wait about 2 minutes, then turn it back on.

What to Check Next on This Bosch Washer Bosch Washer Error F05: Use the code or symbol as the starting clue, then confirm the actual symptom and cycle stage before ordering parts. 1. Unplug the washer before opening panels, touching wiring, or reaching near the drain pump, door lock, inlet valve, motor, or control area. 2. Verify the simple cause first: check the door latch, load balance, detergent level, inlet water flow, drain filter, hose position, and anything blocking the cycle stage shown by the code or symbol. 3. Clean accessible filters and hose screens, remove debris from the pump area when the model design allows it, then reconnect anything that was loose before running another test cycle. 4. Test the washer during the same fill, wash, drain, spin, lock, or control step where the warning appeared; measure voltage or resistance only if you are equipped to do that safely. 5. Inspect the matching part path instead of guessing: door-lock issues point toward the latch circuit, drain symptoms toward pump or hose restrictions, fill symptoms toward inlet supply, and control-response symptoms toward wiring or board checks. 6. Replace a part only after the symptom repeats and the model-specific checks point to that part category. Match any replacement to the complete Bosch model number on the appliance tag. If the issue returns after these checks, match replacement parts to the complete Bosch washer model number from the appliance tag. The same code can point to different components depending on the exact model and when the failure appears.
