Patent ID: 8695381

Claim:
A method for avoiding maximum vibration in a laundering device, comprising: identifying a first harmonic speed at which vibration is at a maximum during a first spin cycle of the laundering device; setting a current harmonic speed parameter to be equal to the first harmonic speed; identifying a spin speed for a second spin cycle of the laundering device; when the spin speed is within a predefined range of the current harmonic speed parameter, adjusting the spin speed to be outside the predefined range of the current harmonic speed parameter during the second spin cycle; completing the second spin cycle based on the adjusted spin speed; determining that a second harmonic speed at which vibration is at a maximum during a spin cycle subsequent to the first spin cycle is different from said current harmonic speed parameter; and adjusting the current harmonic speed parameter to be equal to the second harmonic speed when it is detected, during each of a plurality of consecutive spin cycles after the subsequent spin cycle, that a speed at which vibration is at a maximum is within a predetermined range of the second harmonic speed.
