Troubleshooting
Electrical
Symptom: Sprayer does not run or stops running.
Perform Pressure Relief Procedure; page 8.
•Plug sprayer into correct voltage, grounded outlet
•Set power switch OFF for 30 seconds and then ON again (this ensures sprayer is in normal run mode).
•Turn pressure control knob clockwise 1/2 turn
•View digital display
To avoid electrical shock or moving parts hazards when covers are removed for troubleshooting, wait 30 sec- onds after unplugging power cord for stored electricity to dissipate. Keep clear of electrical and moving parts during troubleshooting procedures.
If no digital display is available, use control board status light to troubleshoot prob- lems: Turn ON/OFF switch OFF, remove control cover and then turn power back ON. Observe status light. Blinking LED to- tal count equals digital error code i.e., two blinks equals E=02.
