Cause
Hose is too restrictive
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
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
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.
