A medical washer/disinfector, comprising: - a washing chamber for receiving medical articles to be washed/disinfected, - an opening for accessing the interior of the washing chamber, - a door which is movable ∘ from a lowered open position, enabling medical articles to be inserted into or retrieved from the washing chamber through the opening, ∘ and then to a raised stop position, in which the door is located in front of the opening but positioned laterally spaced apart from the opening, ∘ and then to a raised closed position, in which the door is positioned against the opening and seals the opening, wherein the door also passes through the raised stop position when transitioning from the raised closed position back to the lowered open position, the door comprising or being fixedly connected to a first slide surface, - a motor, - a carrier arrangement vertically movable by the motor, the carrier arrangement comprising a second slide surface for enabling slidable contact with the first slide surface, - a spring member connected to the door at a connection area, the spring member being in contact with the carrier arrangement and extending vertically upwardly from the carrier arrangement to said connection area, wherein when the door is in the lowered open position and the motor moves the carrier arrangement upwards, the door is pushed upwards by the spring member until the door reaches said raised stop position at which point further upwards movement of the door is prevented, wherein the pushing upwards by the spring member prevents sliding motion between the first and second slide surfaces during the movement of the door from the lowered open position to the raised stop position, wherein, after the door has reached the raised stop position, continued upward movement of the carrier arrangement causes the spring member to become more compressed, thereby enabling the first slide surface to slide along the second slide surface, whereby the door moves horizontally from the raised stop position to the raised closed position due to the continued upward movement of the carrier arrangement. - a washing chamber for receiving medical articles to be washed/disinfected, - an opening for accessing the interior of the washing chamber, - a door which is movable ∘ from a lowered open position, enabling medical articles to be inserted into or retrieved from the washing chamber through the opening, ∘ and then to a raised stop position, in which the door is located in front of the opening but positioned laterally spaced apart from the opening, ∘ and then to a raised closed position, in which the door is positioned against the opening and seals the opening, wherein the door also passes through the raised stop position when transitioning from the raised closed position back to the lowered open position, the door comprising or being fixedly connected to a first slide surface, ∘ from a lowered open position, enabling medical articles to be inserted into or retrieved from the washing chamber through the opening, ∘ and then to a raised stop position, in which the door is located in front of the opening but positioned laterally spaced apart from the opening, ∘ and then to a raised closed position, in which the door is positioned against the opening and seals the opening, wherein the door also passes through the raised stop position when transitioning from the raised closed position back to the lowered open position, the door comprising or being fixedly connected to a first slide surface, - a motor, - a carrier arrangement vertically movable by the motor, the carrier arrangement comprising a second slide surface for enabling slidable contact with the first slide surface, - a spring member connected to the door at a connection area, the spring member being in contact with the carrier arrangement and extending vertically upwardly from the carrier arrangement to said connection area, wherein when the door is in the lowered open position and the motor moves the carrier arrangement upwards, the door is pushed upwards by the spring member until the door reaches said raised stop position at which point further upwards movement of the door is prevented, wherein the pushing upwards by the spring member prevents sliding motion between the first and second slide surfaces during the movement of the door from the lowered open position to the raised stop position, wherein, after the door has reached the raised stop position, continued upward movement of the carrier arrangement causes the spring member to become more compressed, thereby enabling the first slide surface to slide along the second slide surface, whereby the door moves horizontally from the raised stop position to the raised closed position due to the continued upward movement of the carrier arrangement.
