The invention relates to a roller washing machine and a water leakage judgement method. The roller washing machine comprises a casing with a front panel, a washing cylinder, a controller and a drainage device, and the washing cylinder, the controller and the drainage device are arranged in the casing. The front panel is provided with a recess used for mounting a door body, the center of the recess is provided with a clothes putting port communicated with the washing cylinder, the circumferential wall of the recess is provided with water leaking holes, a water receiver communicated with the water leaking holes is arranged in the casing, a water level detection device is arranged in the water receiver, the water receiver is provided with a draining mechanism, and the controller is connected with the water level detection device, and obtains water leakage information in dependence on the water level change in the water receiver, and executes a water leakage response measure corresponding to the water leakage information. By employing the roller washing machine and the water leakage judgement method, whether water is leaked in the door sealing position of the washing machine can be detected, and a water leakage response measure can be executed in dependence on the water leakage information.
