Reinstall wash arm end caps; do not overtighten. Reinstall wash / rinse arms in their proper location. Orient arms so upper nozzles point down and lower nozzles point up. Arms in the prewash section each have two tubes (the slightly longer arm goes below). The wash / rinse arms with five tubes fit in the upper brackets. Arms with four tubes fit in the lower brackets.

To install the arms, rest the rear wash arm manifold on the track (open end of the box is at the rear so it can connect to the O-ring assembly in the rear). Push wash arms to rear (Fig. 24). Latch wash arms in place (Fig. 25).

Rinse the tank bottom, removing any accumulation of food soil (Fig. 26).

Replace the pump intake screens, strainer pans, and strainer baskets. Leave the machine doors open to allow the interior to air out and dry. Rehang curtains.

Clean machine exterior like any other stainless steel appliance. Use damp cloth and mild soapy water.

If equipped with photoelectric sensor rinse, flush the openings where the sensors are located at the load end of the machine (Fig. 27).
