Yes, shorting between components is the worry. As long as you dry out the motor well and no water remains caught within the motor, it shouldn't become a problem.
With electronics, very often, there is a slight bit of power on at all times. It may be only a simple EPROM (Erasable/Programmable/Read Only Memory.
Those chips can hold a charge for more than a decade with no power source other then thier own.
When wet, they cause a short between the components in the chip and fry the works.
That's why electronics can be fried even when they aren't plugged in.
