Startup Procedures 

 

 

 

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

 

2.  Drain the water if it is cold, by pressing and holding the drain switch until all 

the water is completely drained from the dishwasher.  

 

3.  Check the internal drain screen if necessary, remove it from the machine and 

clean it out.  After cleaning, reinstall it properly back into the sump. 

 

4.  Check the wash arm spray tips.  If they are clogged, clean with soft bristle 

brush and a toothpick, and rinse well in sink.  Reinstall the wash arms. 

 

5.  Press and hold the Fill

 

 switch until the water overflows into the wash scrap 

accumulator. 

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

(it should be between 120

°

F 66

°

C and 140

°

F, 77

°

C). 

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

and hold the start-switch for 2 to 3 seconds while the wash-cycle is started. 

 

8.  After the machine stops, lower the door, slide the dish-rack out onto the door 

and allow the contents to dry, before stacking. 

 

 

When the door is lowered during a cycle, the machine will automatically stop running. 

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

  

(

The Water and Chemicals to the dishwasher must be programmed by a qualified chemical specialist)

 

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