Warewasher and associated spray arm assembly

Abstract:

A warewash machine includes a chamber for receiving wares, the chamber having at least one spray zone in which a liquid is recirculated from a tank to a spray tube assembly having a plurality of spray nozzles. The spray tube assembly includes a plurality of spray tubes, each including an input end and a distal end connected to a tube support, which has a fixed part and a cover movable between a closed and open positions. Each distal end has an opening that is covered in the closed position and uncovered, perhaps fully, in the open position. The tube support may include at least one latching assembly for holding the cover in the closed position. The cover and the access door may be cooperatively configured such that, when the cover is in the open position, the cover prevents the access door from moving to the closed operating position.
