21:11 is a service station error
You will need a specialist or if you are tech savy you can check if all the wires of the servicestation are connected or if the service station is properly adjusted.

21:11 - Service Station cannot be detected or the Service Station is badly adjusted.

Just a electronics enthusiast trying to fix everything.
