ABSTRACT:
A dishwasher includes a tub, a fluid circulation assembly, and a water flow blocking mechanism. The assembly includes a pump, which is in flow communication with a lower spray arm via a water passage and at least one other spray arm via a conduit. The water flow blocking mechanism includes a water flow blocking device, a magnet, and a magnet positioning device. The water flow blocking device is normally positioned in a pocket in the conduit. The magnet positioning device is configured to move the magnet from a first position to a second position. When the magnet is in the first position, the water flow blocking device is maintained in the pocket by magnetic forces from the magnet. When the magnet is in the second position, the water flow blocking device is not retained in the pocket by magnetic forces of the magnet.
