This may be a fault with the wiring to the pump or the pump motor itself.Even though this is new it is possible that it has an internal electrical fault causing this issue here with it needing replaced again under parts warranty.I would have this tested to be sure of the cause then repaired from there.
In some cases there will be a bleed or pump drain screw that can be removed to bleed out the fluid then the jack retracted and held up into place with a strap.
