General Problem: Circuit Breaker is Tripping
Specific Problem
Cause
Solution
Building circuit breaker opens 
as soon as sprayer is turned 
on.
NOTE: Remove enclosure 
mounting screws and pull 
enclosure away from drive 
housing. Take care not to pull 
on leads from electrical cord 
and power switch.
Sprayer electrical wiring is 
pinched or insulation is dam-
aged.
Repair or replace any damaged wiring or termi-
nals. Securely reconnect wires.
Wires between pressure con-
trol switch and control board 
are pinched.
Motor armature is shorting.
Check for shorts. See Motor Diagnostics, page 
23. If shorts are evident, replace motor using 
Motor Kit, page 26.
Control board is damaged.
CAUTION: Do not perform 
control board diagnostics until 
you have determined the 
armature is good. A bad 
motor armature can burn out 
a good motor control board.
See Control Board Diagnostics, page 25. 
Replace control board if damaged using Control 
Board Kit, page 26.
