A mechanism for unlocking an elevated lower rack is provided in an arrangement for a dishwasher being capable of elevating the lower rack from a lower position to an upper position and locking the elevated lower rack in the upper position. The elevating arrangement may include a spring loaded pivot arm arrangement to be attached in one end to a tub of the dishwasher and in another end to the lower rack for elevating the lower rack from the lower position inside the tub to the upper position at least partially outside the tub. The elevating arrangement may further include a locking mechanism arranged between the spring loaded pivot arm arrangement and the lower rack, which may lock the spring loaded pivot arm arrangement when the lower rack has been elevated to the upper position, thereby fixing the lower rack in the upper position.
