Sprayer does not run at all

Check transducer or transducer

1.

Set sprayer to OFF and disconnect power to

 

connections (control board is not

 

sprayer.

Digital display shows E=03

 

detecting a pressure signal).

 

 

 

2.

Check transducer and connections to control board.

 

 

 

 

3.

Disconnect transducer from control board socket.

 

 

 

Check to see if transducer and control board

Set sprayer ON and control knob to 1/2 turn

 

 

 

clockwise. If sprayer runs, install new transducer.

 

 

 

Replace control board if sprayer does not run.

 

 

7.

Check transducer resistance with ohmmeter (less

 

 

 

than 9k ohm between red and black wires and 3-6k

 

 

 

ohm between green and yellow wires).
