A laundry appliance comprising: a perforated rotatable drum for dehydrating a clothes load, a substantially rigid, free standing drum support means supporting said drum rotatably but non-translatably in relation to a support surface, driving means for rotating said drum at speed thereby dehydrating the load, and a system for compensating for imbalances of said drum and any load carried therein during dehydration of the load, said system comprising: first sensing means located at one or more positions on the drum spin axis for detecting rotational imbalance in the load, a digital processor which in use receives as inputs signals from said first sensing means, and programmed to calculate the value and position of one or more masses required to be added to the drum to correct the sensed imbalance, correction means for adding one or more masses to said drum, said processor controlling such additions such that the resultant value and position is substantially similar as the calculated value and position to correct the imbalance, wherein said processor is further programmed with software causing said processor to carry out the following steps prior to activation of said correction means: 1) monitoring the rotational imbalance based on the output of said first sensing means; 2) energising said driving means to redistribute the load within said drum until said estimated imbalance is below a first predetermined threshold; and 3) energising said driving means to apply a further faster rate of rotation to said drum so as to effectively dehydrate said load.
