19. TROUBLE SHOOTING GUIDE

BAD CLEANING RESULT
First check if:
• the water level is correct (see chapter 13)
• there is foam in the water (see chapter 13)
• the water is regularly changed (see chapter 12)
• the amount of shot medium is correct (see chapter 12)
• original shot medium is being used (see chapter 5)
• foreign detergents has been used (see chapter 4)
Then check if:
• the flush pipes (see pictures 5 and 6) are blocked
• check that the shovels (see picture 16) are assembled
correctly
• the hoses connecting the pump with the flush pipes
have worked themselves loose from either the pump
or the flush pipes
• The dynamic flush pipe (see picture 6) is moving
(if not, contact your dealer)
If all the above items are correct, then contact your dealer
for examination of the internals in the pump. This could be
the case as the machine approaches 20,000 wash cycles.
FLUSH PIPES ARE BLOCKED
A flush pipe (see pictures 5 and 6) may be blocked for
the following reasons:
• A valve cap or other foreign object has got trapped
in the nozzle of the flush pipe
• The machine has been operating with too low water
level
• There is too much shot medium in the machine
• Non approved plastic beads has been used
• There is foam in the water because a non-approved
detergent has been used
• There is foam in the water because it is very dirty
To check if a flush pipe is blocked, put a finger or a piece
of soft hose into the nozzle (see picture 19). In case a
pipe is blocked, dismantle the shovel (see picture 18).
PLEASE NOTE: Left and right shovels are different from
each other, see picture 16. Do not mix them!
A mix up could lead to damages on wheels!
Remove the two M6 nuts, remove the rubber nozzle and
clear the blocked pipe by means of compressed air. If
needed, extend your air gun with the enclosed air hose
and work it all the way down towards the pump (see
picture 18 and 19).
Caution: Please read chapter 3, Safety Information
before removing the MotorCompartmentDoor.
Then start a short wash cycle to clean out the pipes and
finally fit the flush nozzle and shovel back into place.
If a valve cap or some other object blocks the pipes
repeatedly, this must be removed from the shot
medium. Again, it's strongly recommend that the valve
cap is removed from the wheel before washing as it can
cause operational disturbances if it falls off during the
wash cycle (see chapter 7).
