Abstract (en)
An appliance and method is provided that can determine load imbalance or out-of-balance conditions. The appliances that typically apply load imbalance detection are clothes washers. A method of imbalance detection includes identifying parameter values that fluctuate with load imbalance over a predetermined sample period (201) and determining a target parameter value from the identified parameter values (202). The method further includes calculating a parameter spread of the parameter values by comparing parameter values to the target parameter value (203). The method further includes converting the parameter spread into a weight value that reflects an imbalance condition.
