•The controller checks the state of the wash sump float switch. If it is in the closed (sump
full) position, then the controller proceeds to the next step. If it is in the open (sump not
full) position, then the fill solenoid is opened and fills the sump until the float switch
closes at which time the fill solenoid is closed. On units equipped with the heat
exchanger option, the water is preheated to 180°F (82°C) prior to entering the unit. On
units equipped with the cold water prewash option, a separate fill solenoid, attached to a
cold water line, is used to fill the unit. While the machine is filling, the FILL indicator
message is displayed. When the fill solenoid closes, the FILL indicator display is
extinguished.
WARNING: BURN HAZARD
•Doors, washer interior and washed wares may be hot.
•Hot water/steam may be sprayed through door opening if door is
opened too soon - press STOP button and wait until water flow stops
before opening door.
