<p>9D-DW-13565 A flood control arrangement for dishwashers in which the in-flow to the dishwasher tub from the water supply line is automatically terminated in the event the tub water rises to a flood level. The arrangement includes a sealing plunger disposed in a plunger body member housing installed downstream of the water fill valve. The sealing plunger tends to be moved to the sealing position by the line water pressure to shut off in-flow to the dishwasher but is blocked from movement to this position whenever the water level is below the flood level by the stem of a float positioned in the dishwasher tub. When the water level in the tub approaches the flood level, the float rises in the tub to a position whereat the float stem releases the sealing plunger to allow it to move to the sealing position and shut off further flow to the dishwasher. The float stem either causes the sealing plunger to be tilted off a sealing face or prevents it from moving laterally in the line to the sealing position in order to produce the blocking action.</p> |
