Abstract
The present invention relates to a locking system for a drawer of a drawer dishwasher and a method for unlocking a drawer of a drawer dishwasher. The locking system includes a locking device for locking a drawer of the drawer dishwasher to a chassis or frame of the dishwasher; an opening attempt sensor for detecting an opening attempt of the drawer; and a control unit connected to the opening attempt sensor and the locking device. The control unit is arranged to trigger stop of a dishwasher pump of the dishwasher based on a detected opening attempt, and wherein the control unit is further arranged to trigger the locking device to unlock after the dishwasher pump has been stopped. Thereby, there is provided a reliable and safe way of opening the drawer during a washing program without the risk of hot water splashing out onto the user or onto the floor.
