A new mechanism of transition to instability is treated arising for vertical motions with phase transition in horizontally infinite two-dimensional domains of a porous medium. Destabilization of a plane interface takes place at zero wave number being accompanied by reversible bifurcations indicating the formation of a secondary flow with a shifted phase transition interface. Sub- and supercritical structures in a neighbourhood of the threshold of instability obey the weakly nonlinear diffusion equation. As an illustration of the transition in question we consider two physically different examples of motion in a porous medium.
