[0002] The water circuit of a dishwasher generally includes a water pump, a water diverter valve, an upper spray arm assembly and a lower spray arm assembly. The water pump is connected to the water diverter valve, and the water diverter valve is respectively connected to the upper spray arm assembly and the lower spray arm assembly. Water is pumped by a single water pump and then diverted to the upper spray arm assembly and the lower spray arm assembly through the water diverter valve to drive the upper spray arm assembly and the lower spray arm assembly to rotate and discharge water. However, there will be a loss of water pressure when diverting through the water diverter valve. Therefore, a higher-power water pump is required to ensure the normal operation of the upper spray arm assembly and the lower spray arm assembly, but this will increase costs.

[0003] Therefore, further improvements are necessary. Summary of the invention
