Upper Vessel Vacu-um
too High
Check Air Press./WW Drain blockage?
Maximum vacuum level setting exceeded. Remove any
blockage in the wheel washer filter strainer or drain hose
(position 6) between GP Filter eQ and the wheel washer. Under
certain conditions, the maximum vacuum level setting can be
raised by service technicians.

Bottom Cylinder not
Retracted
Check Bottom Cylinder Valve/Pos.
Pneumatic cylinder in upper vessel (position 1) is not returning.
Make sure the piston rod runs free. Check that the drain cone
is not stuck. Check the function and position of the position
.
Tips
: Use the self-test function in the "Self-test" submenu.

Make sure the piston rod runs free. Remove dosing unit and
clean all moving parts. Check the function and position of the
position sensor -.
Tips 1
: Use the self-test function in the "Self-test" submenu.
Tips 2
: A quick clean can be done inside the upper vessel
(position 4) by removing the inspection hatch (position 3) and
using the wash brush provided.

High Water Level in
Upper Vessel
Check Upper Vessel Drain/Fouling
Sensor (position 5) has an incorrect or constant signal. Make
sure the drain is not clogged or that dirt has built up inside the
upper ves-sel (position 4) at the sensor position.
51
High Water Level in
Wheel Washer
Clean WW Level Sensor/Level Tube
Blockage?
Sensor (position 13) has an incor-rect or constant signal. Make
sure that the sensor is not incorrectly aligned or has dirt on its
surface. Also clean the level tube including hose (position 12) if
there are any signs of contamination/foam.
52
Water Transfer Timeout
Check WW Drain Blockage/Vacuum
Lev-el/Vacuum Leaks
Maximum time allowed with vacuum activated is exceeded.
Make sure that the drain hose (position 6) between the wheel
washer and the filter unit is not blocked. Clean if necessary.
Make sure there is no vacuum leak when vacuum is activated.
The vessel including drain must not leak. Check/clean as
necessary the bottom outlet and check the gasket on the
inspection hatch.
Tips
: Use the self-test function in the “Self-test” submenu.

N/A
Check Flocculation Powder Level
Make sure the flocculation powder is not stuck or formed
obstructions in the tube (position 20). Fill up if necessary. For
longer inactive periods, it is recommended that powder be
removed in order not to absorb moisture.
61
