A method, system, and computer-program product for preventing overfilling in a dishwasher are disclosed herein. According to one embodiment, a method for preventing overfilling in a dishwasher is provided, wherein the dishwasher includes a water valve for providing water to the dishwasher and a drain pump for removing water from the dishwasher. The method comprises detecting an overfill condition in the dishwasher with at least one detection device, wherein the overfill condition corresponds to a water level in the dishwasher that is greater than a predetermined threshold. The method further includes controlling the drain pump and the water valve in response to detecting the overfill condition in order to facilitate removal of the overfill condition.

A method of operating an appliance includes receiving an initiation trigger to perform a flush operation, supplying water to a container of the appliance, draining the supplied water from the container, measuring a temperature of the supplied water to the container, determining that the temperature of the supplied water is above a predetermined temperature threshold, and halting the supply of water to the container via the water supply.

A turbidity sensor assembly for a dishwasher appliance is provided. The turbidity sensor assembly measures the turbidity of wash fluid in a manner similar to conventional turbidity sensors, but also includes an integral water level indicator. The water level indicator is an opaque buoyant ball that rises and falls with the water level to provide a water level indication that can be used to shut off the drain pump when the sump is empty. More specifically, when the water level drops below a predetermined level, the opaque ball blocks the transmission of light between the emitter and receiver of the turbidity sensor, thus indicating that the sump is almost empty. As a result, the pump operating during a drain cycle need only operate long enough to drain the sump, and this may be achieved without an additional measuring device or complicated control system.

A conveyor warewasher includes at least one spray zone with multiple nozzles for spraying liquid onto wares passing therethrough, the spray zone including a tank for collecting sprayed liquid. The tank includes a drain outlet at the bottom of the tank for draining of the tank and a drain stop movable between a drain outlet closed position and a drain outlet open position. A drain control assembly includes a drain actuator operatively connected to cause movement of the drain stop between the drain outlet closed position and the drain outlet open position, and the drain actuator is moved by a powered device.

A condition warning system for an apparatus such as a pot and pan washing machine, a control system and control methods for a pot and pan washing machine are provided. The condition warning system includes a control system that monitors operational, safety or compliance parameters of an apparatus, and a light that illuminates a location below (or above) an operator's direct line of sight, and which is outside of the operator's direct line of sight. The control system and control methods include a punitive wash action lockout, an extended wash cycle time, and a deep clean wash cycle.

Provided herein is a method performed by an appliance for washing and rinsing goods of detecting process water added to a sump of the appliance during interruption of operation of the appliance, upon recommence of appliance operation, and an appliance performing the method. The method may include detecting process water added to a sump of the appliance during interruption of operation of the appliance, upon recommence of appliance operation. The method may include increasing operating speed of a circulation pump of the appliance to a target speed, measuring an indication of circulation pump pressure or process water flow rate through the circulation pump, and determining that process water has been added to the sump of the appliance during the interruption in case the measured pressure or flow rate is maintained at a sufficient level after the speed of the circulation pump has reached the target speed.

A beverage container washing system may utilize a heated wash fluid circulation system to circulate wash fluid retained in a line between a tank and a sprayer to enable fluid that is supplied to the sprayer to be maintained at a suitable temperature for washing and/or sanitizing a beverage container, and in many instances regardless of the amount of time between wash cycles.

A method of operating a dishwasher having a wash tub and a reuse tank for storing liquid for subsequent reuse, wherein the condition of the water in the reuse tank may be monitored and/or acted upon to limit the likelihood of undesired effects associated with the growth of micro-organisms in the liquid.

A dishwasher has a treating chamber for receiving dishes for treatment according to an automatic cycle of operation and a dispensing system for storing and dispensing a treating chemistry to the treating chamber during the cycle of operation. The dishwasher may dispense a treating chemistry when a temperature of a liquid in the treating chamber satisfies a predetermined temperature threshold. The temperature of the liquid may be maintained to satisfy the predetermined temperature threshold for a predetermined period of time based on the treating chemistry.
