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.
