"An E21 error on a Bosch Avantixx Wash & Dry usually means there’s a problem with the motor or its control system. In simple terms, the machine is struggling to turn the drum properly.
What E21 typically indicates
Most commonly, E21 points to one of the following:
Motor carbon brushes worn out (very common on older Bosch machines)
Drum not turning freely (jammed or stiff bearings)
Motor tacho (speed sensor) fault
Wiring issue between the motor and control board
Less commonly: control module fault"

"Hi, I have one of these machines , I had the same error code on mine , and I had the pump motor replaced. It wasn’t the control panel as this was fully working and enabled."
