Check motor wiring connections
Check for locked or frozen pump or drive train
If all motor wiring connections are OK and pump/drive train
are not locked up, replace motor
Check all wire connections from motor to control board
If connections are all ok, allow sprayer to cool. If sprayer

sprayer in cooler location with good ventilation. Make sure
motor air intake is not blocked.
Make sure prime valve and gun are open
Make sure no flow obstructions or clogged filter
Make sure the motor air intake is not blocked
Make sure control board is properly connected to the back
plate and that conductive thermal paste is used on the
power components, Fig. 3
Check for locked or frozen pump or drive train
Check for possible short circuits in wiring
Check pressure output and replace transducer if pressure
