Dishwasher has rotary slide valve first brought to reference position from unknown position without reference to controller, then moved for defined period to desired position per displacement

摘要

The dishwasher has a wash container with at least two spraying devices that subject items in the wash container to liquid delivered by a circulating pump, a reversing device with a control element for supplying the spraying devices, an actuator drive (40) for positioning a rotary slide valve actuating element with a motor (31) for the rotary slide valve and a controller for controlling the dive and determining the position of the rotary slide valve. The rotary slide valve is first brought to a reference position (R) from an unknown position without reference to the controller and then moved for a defined period to a desired position for each desired displacement of the valve.
