TROUBLE SHOOTING GUIDE
BAD CLEANING RESULT
First check if:
• the water level is correct (see chapter 12)
• there is foam in the water (see chapter 12)
• the water is regularly changed (see chapter 11)
• the amount of ShotMedium is correct (see chapter 11)
• original ShotMedium is being used (see chapter 11)
• foreign detergents has been used (see chapter 4)
Then check if:
• the flush pipes (see pictures 5 and 6) are blocked
• the hoses connecting the pump with the flush pipes have
worked themselves loose from either the pump or the
flush pipes
• FOR SILVERSTONE 12: 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 ShotMedium 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 18).
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.
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 ShotMedium.
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).
