Electrical

Symptom: Sprayer does not run, stops

running, or will not shut off.

Perform 

Pressure Relief Procedure

, page

9.

1.

Plug sprayer into correct voltage, 

grounded outlet.

2.

Turn the ON/OFF switch 

OFF

 wait 30 

seconds and then turn power back 

ON

 

again (this ensures sprayer is in normal 

run mode).

3.

Turn pressure control knob clockwise 

1/2 turn.

4.

View digital display or remove control 

box cover to view control board status 

light. To determine which code (or any 

other code besides voltage supply) 

refer to the control board status light. 

Turn the ON/OFF switch 

OFF

, remove 

the control cover then turn power back 

ON

. Observe the status light. Blinking 

LED total count equals the error code 

(for example: two blinks equals CODE 

02).

Keep clear of electrical and moving parts 

during troubleshooting procedures. To 

avoid electrical shock hazards when 

covers are removed for troubleshooting, 

wait 7 seconds after disconnecting power 

cord for stored electricity to dissipate.
