1. A mechanism for a door of a domestic electrical appliance, the mechanism comprising:
a door latch for holding the door closed;
a latch opener mechanism which, when the door is closed, is configured to be transferred from an inactive position into an active position while at least partially overcoming a holding-closed action of the door latch;
an electrically controllable actuator for displacing the latch opener mechanism from the inactive position into the active position;
a movably arranged pusher, which is separate from the latch opener mechanism and is motionally decoupled therefrom, for force transmission, in the sense of opening of the door, in a force transmission path which bypasses the door latch;
a spring drive configured to provide a spring force which acts on the pusher and which, after the holding-closed action of the door latch has been overcome, enables the door to be pushed open by the pusher; and
a movably arranged blocking member which is separate from the latch opener mechanism and which, in a blocking position with the door closed, is configured to exert on the pusher a blocking action such that a relaxation of the spring drive that is required for pushing open the door is prevented, wherein the blocking member is linearly movable in a direction substantially perpendicular to a direction of movement of at least one of the latch opener mechanism and the pusher,
wherein the blocking member, with the door initially closed, moves, in dependence on a displacement of the latch opener mechanism from the inactive position in the direction towards the active position, into a release position in which the blocking action of the blocking member on the pusher is lifted.
