motorized valve CR3 01-dc12v,when valve body is in place,why there's still current?

A20 actuator CR3 01-dc12v, when customer test valve body in place, and current still can show 2.8mA, what's wrong with it?

Client question:

We think in normal tation, the A20 actuator body is in place, the internal motor is disconnected and the current should be 0. Why current still 2.8mA?

Tonhe engineer answer

Because there is circuit work inside, there will be current. After the actuator valve body is in place, the switch has cut off the circuit to the motor, and the motor has no voltage and no current.
