This invention relates to a dishwasher and a control method thereof, where the effects influencing the washing performance negatively such as filter clogging, rotor blocking, foaming or increase in viscosity are identified by detecting the current drawn by the circulation pump from the network and the solution steps applied to solve this problem. The linkage assembly converts the linear motion into rotary motion of a clamp arm, wherein the clamp arm moves between a clamped position and an unclamped position. The magnetic device also includes a winding formed around at least one of the first leg and the second leg of the first L-core segment or the second L-core segment. During the conditional state, the processor may operate according to rules for a current operational state and also according to rules for a changed state. In use, the switch housing module together with the at least one frequency-matching port component module allow for operation of the configurable high frequency coaxial switch at the desired frequency range.
