. Spray Arm Assembly
The spray arm is mounted to the upper pump housing_Water from the sump is pumped through the upper pump housing where it is directed to the spray arm..The water is discharged from ports in the spray arm as shown in Figure t5..
The velocityof the water discharged from the ports and the angle of the port opening causesthe spray arm to rotate. The rotation of the spray arm assures the distribution of water to all corners of the tub,
A stuck or split spray arm can cause ieaks or poor washability. On complaints of this type, inspect the spray arm closely for a possible split seam. Be sure the spray arm turns freely on the pump housing. If binding is encountered, it wilt be necessary to replace the pump housing or spray arm, or both°
_ 5pray Tube
The spray tube or middle spray arm directs water to the upper rack to assure complete washing and rinsing of all plates and glassware. Water is pumped from the sump, by the lower impeller, through a hose connected to the spray tube or middle spray arm,
On models having the upper rolo rack, be certain the racks turns freely. Unsatisfactory washing of the items in the upper rack will result if the rack binds, is prevented from rotating by a tall item in the lower rack, or water is not being discharged from the spray tube..
