Morphology
push + against + an + open + door
The meaning is directly inferable from the literal image: if a door is already open, pushing against it is pointless, so the phrase naturally maps to making unnecessary effort or persuading someone already willing. This compositional logic is straightforward and cross-linguistically common, so a B1 learner who knows the constituent words should be able to deduce the figurative meaning.
Etymology
The idiom push against an open door shows a simple image: someone keeps trying to push even though the open door already moves easily, so the effort is wasted. That's why it means 'trying to do something that is already easy' or 'making unnecessary effort'.
