1. A method for dishwasher operation, comprising: receiving an operation setting at a dishwasher to be performed by the dishwasher, the dishwasher being configured to receive an input of electrical power at a defined operating voltage and frequency; andcausing an operation of the dishwasher based on the operation setting by causing an inverter of the dishwasher to operate a pump motor of the dishwasher at an electrical power condition different from the defined operating voltage and frequency received at the dishwasher, the electrical power condition at the pump motor causing the dishwasher to operate in accordance with one of a quiet dishwashing cycle, a high water pressure dishwashing cycle, a constant mass flow operation, or a minimum water use operation. 2. The method of claim 1, wherein causing the quiet dishwashing cycle comprises: monitoring that a temperature of water contained in the dishwasher is greater than or equal to a predetermined minimum temperature;if the temperature of the water is less than the predetermined minimum temperature, heating the water to greater than the predetermined minimum temperature; andif the temperature of the water is greater than or equal to the predetermined minimum temperature, operating the pump motor at a reduced speed that is slower than a normal speed that the pump motor is operated at for a normal dishwashing cycle, and for an extended duration time that is longer than a duration time for the normal dishwashing cycle, to wash contents of the dishwasher. 3. The method of claim 2, wherein operating the pump motor at the reduced speed includes inputting one of a piece wise modulated voltage or a piece wise modulated current to the pump motor having an equivalent magnitude that is less than a rated magnitude of the pump motor, or an equivalent frequency that is less than a rated frequency of the pump motor. 4. The method of claim 2, wherein causing the quiet dishwashing cycle further comprises operating the pump motor at the reduced speed to add the water to the dishwasher or remove the water from the dishwasher. 5. The method of claim 1, wherein causing the high water pressure dishwashing cycle comprises: monitoring that a temperature of the pump motor is less than or equal to a predetermined maximum temperature;if the temperature of the pump motor is less than or equal to the predetermined maximum temperature, operating the pump motor at an increased speed that is faster than a rated speed of the pump motor; andif the temperature of the pump motor is greater than the predetermined maximum temperature, operating the pump motor at a speed that is less than or equal to the rated speed of the pump motor to facilitate a cooling of the pump motor below the predetermined maximum temperature. 6. The method of claim 5, wherein operating the pump motor at an increased speed includes inputting one of a piece wise modulated voltage or a piece wise modulated current to the pump motor having an equivalent magnitude that is greater than a rated magnitude of the pump motor or an equivalent frequency that is greater than a rated frequency of the pump motor. 7. The method of claim 1, wherein causing the constant mass flow operation comprises operating the pump motor at varying rotational speeds based on a torque of the pump motor and a water flow from a pump of the dishwasher driven by the pump motor to cause the pump to provide a constant mass flow of water from it. 8. The method of claim 7, wherein operating the pump motor to cause the pump to provide a constant mass flow of water from it comprises operating the pump motor according to a set of curves fit by piecewise linear lines that provide the torque of the pump motor versus the rotational speed of the pump motor to provide the constant mass flow operation based on operating characteristics of the pump motor and the pump. 9. The method of claim 1, wherein causing the minimum water use operation comprises: operating the pump motor at a speed to cause a minimum flow rate from a pump of the dishwasher driven by the pump motor at a start of a dishwashing cycle;calculating a water fill rate and a time to reach a set point flow rate as the start of the dishwashing cycle continues and the flow rate from the pump increases as water is added to the dishwasher;operating the pump motor according to the water fill rate and the time to reach the set point flow rate to fill the dishwasher to a minimum water amount during the dishwashing cycle. 10. The method of claim 9, further comprising operating the pump motor according to the water fill rate and the time to reach the set point flow rate to maintain the minimum water amount in the dishwasher during the dishwashing cycle and avoid cavitation in the pump. 11. A system for dishwasher operation, comprising a dishwasher that includes a controller in communication with an inverter in communication with a pump motor, the dishwasher being configured to receive an input of electrical power at a defined operating voltage and frequency, and the controller including a processor responsive to computer executable instructions which when executed on the processor facilitate the controller to: receive an operation setting to be performed by the dishwasher; andcause an operation of the dishwasher based on the operation setting by causing the inverter of the dishwasher to operate the pump motor of the dishwasher at an electrical power condition different from the defined operating voltage and frequency received at the dishwasher, the electrical power condition at the pump motor causing the dishwasher to operate in accordance with one of a quiet dishwashing cycle, a high water pressure dishwashing cycle, a constant mass flow operation, or a minimum water use operation. 12.
