electric control etc. It draws the water from the wash tank through the pump which also pressurizes and
circulates the water. The temperature of the water in the wash tank is always controlled at the range of
50℃ by the temperature controller. During cleaning operation with the tray in the washer, the upper
and lower washing arms will be rotated by the water pressure. The advantage of this cleaning method is
that the washing arms can clean the bowls and plates in every angles. Upon completing wash with
detergent, the rinse system will kick in within the range of 82℃ high temperature clean water sprayed
from the rinse arm. The last rinse is then used as the next washing water. The rinse detergent can
evaporate the water in the dishware without any trace.
