Laundry appliance

A laundry appliance comprising:

• a perforated rotatable drum for spin dehydrating a wet textile load,
• an electric motor for providing an accelerating force which in use causes said dram to rotate,
• load sensors for detecting a static or dynamic imbalance in the rotation of said drum,
• a controller which receives inputs from said load sensors and is programmed to, in a spin-up phase, energise said electric motor so as to evenly distribute the load within said drum and thereby minimise any static or dynamic imbalance when said drum rotates,
• wherein said controller is programmed to monitor said load sensors for a first condition during a low speed rotation of said drum in which said load is tumbling within said drum, and on detecting said first condition immediately accelerate said drum to a higher speed wherein said load is held centrifugally against the drum,
• wherein said controller is programmed with software which causes it to carry out the following steps:
• (a) energise said electric motor to rotate said drum at a first predetermined rotational speed whereby said load is tumbling;
• (b) monitor said load sensors;
• (c) continually determine one or more characteristic indexes of said input from said load sensors;
• (d) determine the presence of said first condition by comparing said indexes with a first criteria, and
• wherein said load sensors are arranged to sense a parameter being or indicative of at least one of acceleration, velocity, force, or displacement of said drum in at least two independent locations and said processor is programmed to detect, within a single revolution of said drum at said first speed, when the tumbling load within said drum is evenly distributed throughout the period of said rotation.
