Abstract: An overcurrent protection assembly for an appliance includes a cabinet configured to house the appliance, the cabinet including a body and a door, the door movable between an open position and a closed position. The overcurrent protection assembly further includes an overcurrent protection circuit, the overcurrent protection circuit including a switch and a current limiter. The switch is alternatable between an engaged position when the door is in the open position and a disengaged position when the door is in the closed position. The current limiter is in electrical communication with the switch when the switch is in the disengaged position and not in electrical communication with the switch when the switch is in the engaged position. Electricity flowing through the overcurrent protection circuit to the appliance flows at a high current level when the switch is in the engaged position and at a low current level when the switch is in the disengaged position.

Abstract: Systems and methods of detecting current leakage in a heating element are provided. An alternating current signal can be applied to the heating element. The heating element can have an associated line relay and an associated neutral relay coupled to a line terminal of the heating element and a neutral terminal of the heating element, respectively. A control system can be configured to control a sequence of operations of the line and neutral relays such that the magnitude of a leakage current flowing through the heating element to ground is increased. Such increased magnitude can facilitate detection of the leakage current. The detected leakage current can be compared with a leakage threshold. The control system can cease the operation of the heating element if the leakage current is greater than the leakage threshold.

Abstract: Systems and methods for controlling operation of a dishwashing appliance are disclosed. For instance, data indicative of a supply voltage associated with a dishwashing appliance can be received. The supply voltage can be compared to a nominal voltage associated with the dishwashing appliance. One or more voltage control parameters can be determined based at least in part on the comparison. A speed of a motor associated with the dishwashing appliance can be adjusted based at least in part on the voltage control parameters.

Abstract: Systems and methods for controlling one or more operations of a dishwashing appliance are provided. In particular, a supply voltage applied to a heating element of the dishwashing appliance can be determined. The supply voltage can be compared with an acceptable operating range of supply voltages to determine whether the supply voltage is within the acceptable operating range and, if the supply voltage is not within the acceptable operating range, one or more operations of the dishwashing appliance can be controlled based at least in part on the determined supply voltage. For instance, an amount of time during which the heating element is active during one or more operational cycles can be adjusted to compensate for the determined supply voltage.

Abstract: Printed circuit board assemblies providing fault detection are provided. One example printed circuit board assembly includes a substrate layer. One or more solder pins are located on a rear surface of the substrate layer. The printed circuit board assembly includes a non-conductive layer adjacent to the rear surface of the substrate layer. The printed circuit board assembly includes a conductive layer adjacent to the non-conductive layer. The conductive layer is electrically connected to a ground. The printed circuit board assembly includes a mounting surface. The printed circuit board assembly includes a support layer compressed between the conductive layer and the mounting surface. The support layer applies a mechanical force that presses the conductive layer towards the non-conductive layer.
