TROUBLESHOOTING
PROBLEM CORRECTIVE ACTION
Unit will not turn
on.
1. Make sure the pressure washer is OFF. Plug in the electrical cord to a
grounded 120 volt outlet (no electrical extension cord should be used).
If the electrical cord will not plug into your outlet, your electrical outlet is
not properly grounded and should not be used. Use another electrical
outlet.
2. If this did not correct the problem, try plugging into another electrical
outlet and repeat the above procedure. If it is still not working, call
Customer Service. 1-866-235-5112
The high pressure
(HP) hose will
not connect/stay
connected to
the spray gun. Is
this a spray gun
problem?
1. In most cases, the spray gun is not the problem. The problem is the
rubber sleeve covering the fitting at the end of the high pressure hose. It
has likely slipped up toward the metal tip. To fix: wiggle, twist and/or pull
the rubber sleeve down until the entire tip is visible plus an 1/8 in. of the
metal fitting below the tip. Now try to insert the hose tip into the spray
gun. It should “click” into place and will not come out until the hose is
released by pushing in the lever on the underside of the gun. You may
cut away the end of the sleeve with a sharp knife if unable to move the
sleeve down. Be careful not to cut or puncture the hose.
The unit is running
but there is no
water flow.
1. Power should NOT be turned on until water comes through the spray
gun. Doing so will damage the motor.
2. Check the water source.
3. Eject the nozzle from the lance to determine if clog is coming from the
nozzle (If nozzle is clogged, see nozzle cleaning instructions under
“Cleaning nozzles”).
4. Take off the lance and just spray out of the spray gun. This will indicate
if the problem is with the lance.
5. Check Garden Hose Adapter for loose connection and the filter for
debris.
Why is water
leaking where the
high pressure hose
connects to the
spray gun?
1. Make sure there is an o-ring at the end of the metal tip of the high
pressure hose. If no o-ring is present, the connection between the
hose and spray gun will leak. O-Ring Replacement Kit (D) is included
with purchase. Additional O-Ring Kits are available online at www.
arblueclean.com or call Customer Service at 1-866-235-5112 to place
an order.
I can’t remove the
lance from the
spray gun. What
should I do?
1. All lances are attached and removed from the spray gun in the same
manner. Insert the end of the lance into the spray gun. Press the spray
gun and lance together (about a 1/8 in.) and turn the collar of the gun
clockwise. The lance will lock in place. Remove the lance by reversing
this procedure. Press the spray gun and lance together and turn counter
clockwise. The lance will slide out.
2. Hold the spray gun and lance in an upright position with the nozzle
end on the floor. Push the whole assembly straight down to loosen the
connection, and then follow the removal process again. You may also
spray soapy water or a lubricant in the area where the lance connects to
the spray gun.
The pressure
washer turns on for
2 seconds, shuts
off, and will not
turn back on. Do
I have a defective
unit?
1. When the water is connected, the accessories are assembled properly,
and the power is turned on, the pressure washer may turn on for 1 - 2
seconds to prime the pump. It automatically shuts off and waits for the
spray gun trigger to be pressed. When the trigger is pressed, water
starts flowing through the pump. The water sensor in the pump “senses”
the moving water and automatically turns the pressure washer on.
2. Turn the power off, hold in the trigger on the spray gun so that you have
a steady stream of water. While you are holding the trigger open on the
spray gun, at the same time, turn the power on.
