The present invention relates to a dishwasher and a manufacturing method thereof.

The dishwasher according to an embodiment of the present invention includes a water guide extending upward from a sump and supplying washing water to an upper nozzle and a top nozzle, and the upper pipe and the top pipe are separately provided to the water guide, so pressure of the washing water applied to the upper pipe and the top pipe can be reduced.

A dishwasher appliance with a tub that defines a wash chamber is provided. A bottom wall of the tub defines a volute. An impeller is positioned within the volute of the bottom wall, and a motor mounted to the tub at the bottom wall of the tub. The motor is coupled to the impeller such that the motor selectively rotates the impeller within the volute of the bottom wall. A related method for forming a unitary tub for a dishwasher appliance is also provided.
