Operation 

 

Please follow the instructions given here before each shift to assure trouble free operation. 

2.  Drain the water if it is cold by activating the drain switch until all the water is 

out of the machine.  

3.  Check the drain screen and, if needed, remove it from the machine and clean 

it out.  After cleaning, replace it properly into the sump housing. 

4.  Check the wash arm spray tips.  If they are clogged, clean them with a 

toothpick and rinse them at the sink.  Replace the wash arms. 

5.  Press and hold the fill switch until the water overflows into the scrap 

accumulator. 

6.  Once a proper water level is established, check the temperature of the water 

(it should be approximately 140

°F, 60°C). 

7.  Insert the tray of dishes into the machine and close the doors.  The machine 

will automatically start when the doors are closed.  

8.  After the machine stops, raise the doors, remove the tray of dishes and allow 

to dry before stacking. 

If the doors are lifted during a cycle, the machine will automatically stop running. 

The EST will run through the wash and rinse cycles automatically feeding the proper chemicals 
and then turn itself off. 

In an emergency you can turn off the machine by turning off the master switch located on the side 
of the control box.
