A dishwasher appliance connected to a water supply circuit includes a tub defining a wash chamber; a pump in fluid communication with the wash chamber; a user interface comprising at least one input; and a controller operably coupled with the user interface and the pump, the controller being configured to perform a winterization operation. The winterization operation includes determining that a municipal water source has been disconnected from the water supply circuit; supplying a volume of water to the wash chamber after determining that the municipal water source has been disconnected; determining that the volume of water within the wash chamber is greater than a predetermined minimum volume of water; circulating, via the pump, the volume of water within the wash chamber for a predetermined length of time; and draining the volume of water from the wash chamber after circulating the volume of water for the predetermined length of time.

The invention provides a dishwasher with a residue disposal device, comprising a housing and a liner, the liner is arranged in the housing, a spray assembly and a water collection assembly are arranged in the liner, the spray assembly is connected to the water collection assembly, the water collection assembly is provided with a drain hose, a residue disposal device is arranged on the drain hose and connected to the water collection assembly by means of a return pipe, and a three valve is arranged at a joint of the return pipe and the drain hose. The requirement for disposing residues in sewage in a water cup can be met, that is, a closed water path from the water collection assembly to the residue disposal device, the drain hose and the water collection assembly is formed, and under the action of a negative pressure generated by the residue disposal device arranged on the closed water path, water flows unidirectionally to wash the water cup, thus reducing the quantity of residues in the water cup. The requirement for discharging residues can be met, that is, the residue disposal device can replace a drain pump to form a discharge water path from the water collection assembly to the residue disposal device and the drain hose to promote processed food residues to be discharged from the drain hose. The whole process is implemented automatically without manual intervention.
