Cause
Cause Cause
Hose is too restrictive
Cause Cause Cause
The control board is detecting
multiple voltage surges
Check for line obstruction or pack
out. Motor is powered but not able
to turn.
The motor is overheating
Incoming voltage is too low for
sprayer operation
The control board is overheating
Excessive current protection is
enabled
Solution
Solution Solution
Thin and mix material thoroughly to a lower
viscosity.
Use a pump system priming fluid (slime). Wet out
the system.
Use a larger diameter hose.
Thoroughly mix in a pump-aid or performance
admixture to the material.
Solution Solution Solution
Check voltage supply to the sprayer:
1. Turn the motor power switch (S) to OFF and
unplug the sprayer.
2. Locate a good voltage supply to prevent
damage to electronics.
Open the relief valve to relieve pressure. Remove
the obstruction and cycle power off and on. If the
problem continues, contact your local distributor.
Allow the sprayer to cool. If the sprayer runs when
cool, correct the cause of overheating. Keep the
sprayer in a cooler location with good ventilation.
Make sure the motor air intake is not blocked. If
the sprayer still does not run, contact your local
distributor.
Check voltage supply to the sprayer:
1. Turn the motor power switch (S) to OFF and
unplug the sprayer.
2. Remove other equipment that uses the same
circuit.
3. Locate a good voltage supply to avoid damage
to electronics.
1. Make sure the motor air intake is not blocked.
2. Make sure the fan has not failed.
3. Make sure the control board is properly
connected to the back plate and that conductive
thermal paste is used on power components.
4. Replace the control board.
5. Replace the motor.
Cycle the power on and off.
