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
• The cap on the FlexoPowerJet
nozzle is not set to low pres-
sure
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)

• 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
