Abstract: Methods and systems of determining the amount of liquid in a liquid supply tank of a beverage forming machine without a dedicated sensor are disclosed herein. In some embodiments, the beverage forming machine includes a controller capable of determining the amount of liquid in the liquid supply tank based on a gas volume in a reference vessel, such as a conduit, in fluid communication with the liquid supply tank.

Abstract: Methods and systems for employing a sensor to detect two physical characteristics of a liquid in a beverage machine. A sensor may have a conductive probe portion to contact liquid, e.g., to detect a liquid level in a removable water tank, and a thermistor portion to detect a temperature of the liquid.

Abstract: Methods and systems for employing a sensor to detect disconnection of a liquid supply tank and/or a low fill level of the liquid supply tank are disclosed herein. The sensor may have an optical sensor to detect liquid, e.g., to detect a liquid level in a removable liquid supply tank and/or liquid at a pump. The optical sensor can include a body made of a resilient material and including first and second portions and an opening located between the first and second portions. The opening can be configured to receive and frictionally engage with a conduit for carrying liquid, with the first portion configured to support a light emitter and the second portion configured to support a light detector.

Abstract: A dishwasher with at least one guide rail. The guide rail can slidably couple a dish rack to a tub, where the tub defines at least a portion of a treating chamber. The dish rack can carry at least one wheel assembly that includes at least one wheel. The wheel can be contained in a wheel channel of the wheel assembly. The wheel channel can in part be defined by walls of the guide rail. A track closure can rotatably couple to the guide rail for the selective removal of the dish rack from the guide rail.

Abstract: A dishwasher includes a tub at least partially defining a treating chamber, at least one dish rack in the treating chamber, and a rack height adjustment assembly. The rack height adjustment assembly includes an adjuster plate slidably coupled to the at least one dish rack and fixed vertically relative to the tub, the adjuster plate including at least one adjuster detent, a locking lever having a catch end that is biased to engage the adjuster detent to hold the dish rack in place in either a lowered or raised position, the locking lever being pivotally movable relative to the at least one dish rack between an engaging position where the catch end engages the adjuster detent and a release position where the catch end does not engage the adjuster detent and the dish rack is vertically movable between the lowered and raised positions, and an actuator configured to move the locking lever to the release position when the actuator is moved from an undepressed position to a depressed position.

Abstract: In one aspect, a dishwasher includes a tub at least partially defining a treating chamber and defining an access opening, a dishrack, and a guide rail assembly slidably mounting the dishrack to the tub. The guide rail assembly has a guide rail mounted to the dishrack or to the tub and has at least one wheel which is rotatably mounted onto an integral axle of the guide rail assembly to the other of the dishrack or the tub.
