A method of washing dishes in a dishwasher that includes a Start Stop sequence in a wash segment of one or more of the dishwashing cycles. The Stop Start sequence includes the steps of pausing the operation of the wash pump, operating the wash pump to circulate wash water in the dishwasher for a short period of time, and repeating the steps of pausing and operating the wash pump for a short period of time a predetermined number of times. The Stop Start sequence is preceded by, and may be followed by, a period of continuous operation of the wash pump.
Claims16
A method of washing soil particles from dishes in a dishwasher comprising a tub defining a wash chamber, a distribution system for distributing wash liquid to the wash chamber, a drain system for draining wash liquid from the wash chamber;
- and a wash pump having a pump chamber housing a filter system fluidly coupled to the pump, the distribution system, and the drain system, the method comprising the steps of:
- operating the wash pump for a first time interval to circulate wash liquid through the distribution system to the wash chamber during a wash segment of a wash cycle;
- pausing the operation of the wash pump during the wash segment for a second time interval to allow wash liquid in the distribution system to flow back into the pump chamber to flush the filter system;
- and
- operating the wash pump for a third time interval during the wash segment to remove soil particles from the wash liquid into the drain system.
A method of washing dishes in a dishwasher comprising a tub defining a wash chamber, a distribution system for distributing liquid to the wash chamber, and a wash pump having a pump chamber for recirculating wash liquid through the distribution system, the method comprising the steps of:
- A) operating the wash pump for a first time interval to circulate wash liquid through the distribution system to the wash chamber during a wash segment of a wash cycle;
- B) pausing the operation of the wash pump during the wash segment for a second time interval shorter than the first time interval to allow wash liquid in the distribution system to flow back into the pump chamber;
- and
- C) repeating steps A) and B) without an intervening step to provide a stop-start wash sequence during the wash segment.
