Troubleshooting
Electrical
Symptom: Sprayer does not run or stops running. Run
through the pressure relief procedure; see page 7.
• Insert the mains plug into an earthed outlet with the
correct voltage values
•
• 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
In order to avoid electric shock and hazards caused by
moving parts when covers are removed for trouble-
shooting, wait 30 seconds after unplugging the power
cable for stored electricity to dissipate. Maintain a safe
distance between electrical and moving parts during trou-
bleshooting procedures.
If no digital display is available, use the control board sta-
tus light to remedy any problems: Set the ON/OFF switch
to OFF, remove the control board cover and then set the
switch back to ON. Observe the status light. The number
of times the light flashes corresponds to the digital error
code, i.e. two flashes equals E = 02.
