A dishwasher may include a sump configured to store water, a main arm disposed at the sump and configured to supply water from the sump, an auxiliary arm rotatably disposed at the main arm and configured to spray water, and an auxiliary arm connection member disposed at the main arm and configured to rotatably support the auxiliary arm, where the auxiliary arm may include an auxiliary flow passage configured to allow water flow through the auxiliary arm, where the main arm may include a transfer flow passage in fluid communication with the auxiliary flow passage, where the auxiliary arm connection member may include a flow tube disposed at the main arm in fluid communication with the transfer flow passage and the auxiliary flow passage.

A method and appliance utilize one or more sprayers that are coupled to both a liquid supply and an air supply through a common hydraulic circuit such that both liquid and pressurized air can be supplied to the one or more sprayers. A common motor may operate both an air pump and/or a water pump of the appliance. The air pump and/or water pump may supply fluid to one or more sprayers and/or other apparatuses within the appliance.

A dishwasher that includes: a tub; a main arm configured to rotate about a first axis and spray water; an auxiliary arm configured to rotate about a second axis and spray water in the interior space; a stationary gear unit configured to rotate based on rotation of the main arm to generate rotational force and including a plurality of gear teeth; an eccentric rotation unit engaged with one or more teeth of the plurality of gear teeth, and configured to, (i) based on rotation of the main arm, rotate to transfer rotational force of the stationary gear unit to the auxiliary arm and, (ii) based on resistance force from the auxiliary arm, control transfer of rotational force of the stationary gear unit to the auxiliary arm; and a link member configured to rotate the auxiliary arm based on rotational force of the stationary gear unit is disclosed.
