  • Patent number: 11197601
    Abstract: A dishwasher appliance equipped with leak detection features and a method of detecting leak conditions during an operation cycle of a dishwasher are provided. In one aspect, the dishwasher appliance includes a tub having a sump. A pressure sensor is mounted to the sump and is configured to monitor the sump pressure during an operation cycle. If the sump pressure falls below a pressure threshold during a circulation cycle, corrective action can be taken. For instance, a circulation pump circulating wash fluid through the tub can deactivated and a static pressure reading can be taken by the pressure sensor. The static pressure reading can be compared to a static pressure reading taken prior to the circulation cycle. In response to whether the static pressure is within a predetermined range of the static pressure reading taken prior to the circulation cycle, the circulation cycle can be recommenced or aborted.

  • Patent number: 11155953
    Abstract: A water recovery system includes a storage tank that connects to a washing machine, and selectively recovers rinse water from normal operation of the washing machine and then recirculates recovered rinse water back to the washing machine for use in a next wash cycle. This reduces total water usage by the washing machine during each full cycle of the washing machine. Preferably, no wash water or rinse water is discharged to waste until it has first passed through the storage tank. The wash water is first captured or recovered in the storage tank, and then the wash water is discharged as waste during a subsequent rinse cycle. Secondly, rinse water that is recovered in the storage tank is reused in a subsequent wash cycle to reduce the total amount of fresh water needed to complete a full cycle of the washing machine through its wash and rinse cycles.
