Problem Cause Solution
Power switch is on, and sprayer
is plugged in, but motor does not
run, and pump does not cycle. Pressure Control Knob is set at
zero pressure. Turn Pressure Control Knob clockwise to
increase pressure setting.
Motor or control is damaged. Have the sprayer serviced by a qualified
repair person.
Electric outlet is not providing
power. Try a different outlet or test the outlet
with another appliance or circuit tester.
Reset the circuit breaker or replace the
fuse.
Extension cord is damaged. Replace the extension cord.
Sprayer electric cord is
damaged. Unplug the sprayer cord and check for
broken insulation or wires. Replace if
damaged.
Paint and/or water is frozen or
has hardened in the pump. Unplug the sprayer from the outlet. If
frozen, do not try to start the sprayer
until it is completely thawed or the motor,
control board, and/or drivetrain will be
permanently damaged.
Ensure the power switch is OFF, place
the sprayer in a warm area for several
hours, then plug in the power cord and
turn the sprayer ON. Slowly increase
pressure setting to see if the motor will
start.
If paint has hardened in the sprayer, the
pump packing seals, valves, drivetrain,
and/or pressure switch will need to be
replaced. Have the sprayer serviced by a
qualified repair person.
Pump does not prime. Spray/Prime Switch is in Spray
position. Turn Spray/Prime Switch to Prime position
(pointing down)
Inlet screen is clogged, or
suction tube is not immersed. Clean debris from inlet screen and make
sure the suction tube is immersed in fluid.
Pump was not primed with water
or solvent based flushing fluid. Remove suction tube from paint. Prime the
pump with the correct flushing fluid.
Inlet valve check ball is stuck. Remove the suction tube and place a
pencil into the inlet section to dislodge the
ball, allowing the pump to prime properly.
Inlet valve check ball or seat is
dirty. Remove inlet fitting. Clean or replace the
ball and seat.
Outlet check ball or seat is dirty. Remove the outlet fitting. Clean or replace
the ball and seat.
Suction tube is leaking. Tighten the suction tube connection.
Inspect for cracks or vacuum leaks.
Fluids are viscous or sticky. Some fluids may prime faster if the Power
Switch is momentarily turned off so the
pump can slow and stop. Repeat several
times if necessary.
