Run the pressure washer with the gun disconnected until a
steady flow of water appears from the high pressure hose.
Stop if this has this has not been achieved within 25 seconds
and check all the connections. Switch off and connect the
gun, lance and nozzle to operate.
It is important to ensure that all hose and coupling connec-
tions are of good quality, air tight and that all washers are in
good condition and correctly seated in place. Failure to do so
may affect the self priming performance.
Troubleshooting
Problem
Motor refuses to start
Motor stops
Fuses blow
Motor starts but no pressure
Motor "sounds" but fails to start
Pressure pulsating
Pressure too low, but steady
Note: Several types of accessory
will normally deliver a lower pres-
sure
Motor starts up but with restricted
or no working pressure
Bosch Power Tools
Water Tanks with outlet connections
When connecting the pressure washer to a water tank with a
suitable tap outlet, first connect the supply hose (not provid-
ed) to the tank outlet, open the tap to allow the water to dis-
place all the air in the hose and then connect to the pressure
washer.
Possible Cause
Plug not connected
Mains socket faulty
Fuse faulty/blown
Extension cable damaged
Motor protector has activated
Frozen
Fuse faulty/blown
Wrong mains voltage
Motor protector has activated
Fuses incorrectly rated
Nozzle partly blocked
Insufficient power supply
Voltage loss due to use of extension
cable
Appliance not used for a long period
of time
Problems with TSS (Total Stop
System) device
Air in the inlet water supply
hose/pump
Inadequate water supply
Water filter blocked
Water supply hoses squeezed
High pressure hose too long
Nozzle worn
Start/stop valve worn
No water supply
Water filter clogged up
Nozzle clogged up
Corrective Action
Connect plug
Use another socket
Replace fuse
Try without extension cable
Allow to cool for 15 minutes
Wait for pump/water supply hose/accessory to
thaw
Replace fuse
Check that mains voltage corresponds to specifica-
tions on the model tag
Allow to cool for 15 minutes
Change to a mains supply higher than the pressure
washer amp consumption
Clean nozzle
Check that the voltage of the mains power supply
line is the same as that on the plate
Check characteristics of extension cable

Allow pressure washer to run with open spray han-
dle and nozzle at low pressure until regular working
pressure is obtained
Check that the water supply corresponds to specifi-
cations. The minimum specification for the water
supply hose is 1/2" or 13 mm diameter
Clean water filter

Remove high pressure extension hose. Retry (ex-
tension hose max. 7 m)
Change the nozzle
Activate trigger five times in quick succession
Connect water supply
