Problem Solution
Power and/or ready lights do not
illuminate
•if neither light illuminates, verify proper connection at battery
terminal.
•If only one light comes on, light is burnt out. Continue with
service and contact MotorVac for replacement LED board
Car will not shut off with fuel
pump disabled
•Verify proper relay is disabled. For some GM models it may be
necessary to disable the fuel pump by alternate method. Contact
technical support
Car will not run on CarbonClean
1000
•Verify EFI relay was not disabled.
•Verify adapter is properly connected. For most models the fuel
pressure gauge should be working if a proper connection has
been made.
•Remove the canister of cleaning fluid to verify it has been
emptied into the machine.
•Disconnect fuel supply line from adapter attached to vehicle.
Connect any adapter fitting to the fuel supply hose from the
CarbonClean 1000, turn the regulator up to 20 psi to verify flow
from the machine.
Fluid leaks from the can cutter
when air pressure is applied •Can cutter check valve may need replacement. Leave can on
during service. Contact MotorVac for replacement.
Fluid leaks from air regulator
knob when canister is discharged
•Machine was not emptied before adding a new can. Proceed
with service and note length of service. Normal service time is
12-18 minutes depending on the engine. Longer than normal
service time verifies the machine was already full. Inspect for
leaks at next service. If problem persists contact technical
support
Fluid leaks from any other
location
Contact technical support
Service time is too long
•Normal service time is 12-18 minutes. Longer service times can
be expected on vehicles with smaller and more fuel efficient
engines. If the service is excessively long turn air regulator
pressure knob back to zero and disconnect fuel supply line from
adapter. If vehicle continues to run, fuel pump was not disabled.
Service time is too short
•Normal service time is 12-18 minutes. Shorter service times can
be expected on vehicles with larger engines. Confirm that the
leak down test was SUCCESSULLY performed prior to service. If
not vehicle was a leak in fuel pump check valve or regulator and
needs to be repaired prior to service.
•Normal service time is 12-18 minutes. If yes, pressure regulator
was likely set too high allowing the regulator to return the cleaning
solution back to the tank.
If engine struggles while running
on CarbonClean 1000 •Slowly increase the pressure. Do not exceed the pressure
specified in the application guide.
Fluid takes a long time to enter
the CarbonClean 1000
•Ensure that the cans are kept at room temperature
•Ensure that the pressure regulator is turned fully
counterclockwise before screwing the can on
•Observe the sight glass for the inlet filter, replace assembly if the
filter is clogged.
