A dishwasher appliance or pump assembly may include a fluid pump and a vibration damper. The fluid pump may define a center of gravity. The vibration damper may be attached to the fluid pump. The vibration damper may include first and second spring beams and first and second damper masses. The first spring beam may extend longitudinally between a fixed end and a free end and be offset from the center of gravity at a first radial side. The first damper mass may be disposed on the free end of the first spring beam. The second spring beam may extend longitudinally between a fixed and a free end and be offset from the center of gravity at a second radial side. The second damper mass may be disposed on the free end of the second spring beam.

Systems and methods for identifying a motor coupled to an electrical appliance are disclosed herein. The electrical appliance can include a motor assembly comprising at least one electric motor and a filter network including an electrical resistance component and an electrical capacitance component. The electrical appliance can also include a controller electrically coupled to the motor assembly and the filter network, the controller comprising one or more processors and a memory comprising instructions for performing a process. The process can include providing an input signal to the filter network and receiving an output signal from the filter network, the output signal being filtered by the filter network. The process can also include identifying a filter characteristic of the filter network based on the output signal and identifying a type of the electric motor based on the identified filter characteristic.

A dishwashing appliance includes a tub defining a wash chamber for receipt of articles for washing. A sump is a sump positioned at a bottom of the wash chamber for receiving fluid from the wash chamber. A circulation pump is connected to the sump. The dishwashing appliance also includes a mounting cable extending from the circulation pump. The circulation pump is suspended by the mounting cable.

A dishwashing appliance or fluid pump, as provided herein may include a fluid impeller, an electric motor, and a housing. The fluid impeller may be rotatably receivable within a tub of the dishwashing appliance. The electric motor may be in mechanical communication with the fluid impeller to motivate rotation thereof. The electric motor may include a multi-phase winding set sealed within an overmolded insulation. The housing may enclose the electric motor therein. The housing may be receivable within a sump to which water is directed in the dishwashing appliance.

Dishwashing appliances and methods, as provided herein, may include features or steps such as detecting a pressure (P1) at a pressure sensor upstream from a pump while maintaining the pump in an inactive state and activating the pump from the inactive state for an activation period during which the pump remains active to motivate a continuous fluid flow. Dishwashing appliances and methods may further include features or steps for detecting a pressure (P2) at the pressure sensor upstream from the pump during the activation period and initiating a response sequence at the pump based on P1 and P2.

Dishwashing appliances and methods for addressing obstructions therein

A dishwasher appliance includes a drain basin defined at a bottom of a sump of the dishwasher. The drain basin defines a discharge port and a drain pump is in fluid communication with the discharge port for selectively urging a flow of wash fluid through the discharge port to an external drain during a drain cycle. A check valve assembly includes a check valve removably positioned over the discharge port between the drain pump and the drain basin and a positioning arm attached to the check valve for positioning and locking the check valve in place.

Systems and methods for detecting appliance pump cavitation or dry state are provided. An exemplary appliance can include a current measurement circuit configured to provide a feedback signal that describes an inverter current drawn by an inverter providing three-phase power to the pump motor. A control unit of an appliance can detect pump cavitation and dry state by monitoring the feedback signal. Another exemplary appliance can include a motor speed detection circuit configured to provide a motor speed signal describing the speed of the pump motor. The control unit of the appliance can monitor variance in pump motor speed to detect pump dry state or cavitation. An exemplary method includes monitoring either an inverter current used by an inverter to drive a motor or a variance in a rotational speed of the motor.

A fluid filtration assembly for a dishwasher system is described. The dishwasher system includes a tub defining a wash chamber configured to receive dishwasher contents. The fluid filtration assembly includes a filter assembly having a filter material, a filter fluid inlet, and a filter fluid outlet. The filter fluid inlet is in flow communication with the wash chamber and the filter material. The filter assembly further includes a cleaning fluid inlet that is configured to backflush the filter material. The filter fluid outlet is in flow communication with both the cleaning fluid inlet and the filter fluid inlet. The fluid filtration assembly further includes a valve assembly in flow communication with the cleaning fluid inlet through a first flow path.
