Pumping Errors
NOTE: In some error codes listed below, a # symbol is shown as the last digit. This symbol represents the
applicable component number, which can vary. The unit's display will show the applicable number as the
last digit in the code. For example, the F1S# code listed in this table will be displayed as F1S1 if the affected
component is pump 1, F1S2 for pump 2, and so on.

Problem
Pump was driven to
its maximum allowed
speed.
This is a manual stall
test failure when the
pump cannot build
pressure to the target
"Stall Test Pressure."
Will fault after 30
seconds.
Pump failed the stall
test; did not stall on the
upstroke.
Pump failed the stall
test; did not stall on the
downstroke.
Cause
System has a leak
or open valve that is
allowing unrestricted
flow.
Pump is cavitating,
cycling without
restriction.
Viscosity of material is
too thin for nozzle size.
System pressure or
Flow Setpoint is too
high (causing the pump
to work too hard).
No material in the pump
or line.
Leak in the system.
Valve failure, seal
failure, worn rod or
cylinder.
Valve failure, seal
failure, worn rod or
cylinder.
System Errors
Solution
Inspect system for
leaks.
Verify that the pump
is being supplied with
material.
Reduce nozzle size to
create more restriction.
Reduce paint pressure
to lower the flow rate.
Reduce the pressure or
the Flow Setpoint.
Make sure the pump
and down stream color
line are loaded with
material.
Determine if leak is
external or internal
by visually inspecting
the system for fluid
leakage. Fix all loose
or worn hoses, fittings,
and seals. Inspect
all valve seats and
needles for wear, and
replace worn piston or
throat seals.
Replace inlet and outlet
valve and seal for
up stroke. Replace
piston and throat
seals. Replace rod and
cylinder as necessary.
Replace inlet and outlet
valve and seal for
down stroke. Replace
piston and throat
seals. Replace rod and
cylinder as necessary.
