Bosch Washer Error Code F43 (Drum Not Turning) — Denver, CO Repair Help
Getting Bosch error code F43 in Denver? This usually means your washing machine drum is not turning, often because the motor can’t rotate, the system can’t detect drum speed, or something is physically blocking movement.

Why Bosch shows F43
The control board monitors drum rotation. If it detects no movement or incorrect rotation feedback, it stops the machine to protect the motor.
