Cause
Air in the system
High pressure nozzle blocked
worn
Detergent tank empty
Pump draws in air (only pos-
sible in suction mode)
Lack of water
Water inlet hose is too long or
its cross-section too small
Lack of water caused by
blocked water filter
Lack of water because max.
permissible suction height has
not been heeded
The plug is not inserted prop-
erly, i.e. there is no current
The mains fuse is switched off •
The mains voltage is too low or
there is a phase failure.
The pump is blocked or frozen •
Incorrect cross-section or
length of the extension lead
The overload protection has
been activated due to over-
heating or overloading of the
motor
High-pressure nozzle is dirty
Injector is dirty or suction hose
is blocked
Detergent tank empty

Remedy
Vent the system by operating
the spray gun several times at
short intervals. If necessary,
operate the cleaner for a short
time without the high-pressure
hose connected.
Clean/replace the high pres-
sure nozzle
Top up detergent tank or set
detergent metering to "0"
Check that the suction set is
air-tight
Open water tap
Use specified water inlet hose
Clean the water filter in the
water connection (never work
without water filter)
See instructions
Check the plug, lead and
switch and if necessary have
them replaced by a trained
electrician
Switch on the mains fuse
Have the electrical connection
checked
Contact the GRACO customer
service
Use lead with correct cross
section or length
Check that the mains volt-
age and the cleaner voltage
are the same. Switch off the
cleaner and allow it to cool for
at least 3 minutes
