Blockage due to
foreign bodies or
hardened material in
the mixing pipe or
rotor/stator • Remove the foreign bodies and clean the mixing pipe or rotor/
stator
Machine
operator
Water pressure too
low • Check the water pressure at the pressure gauge of the water
fitting (min. 2.5 bar)
• Use a water pressure booster pump if the water pressure is
too low.
Machine
operator
The machine has
stopped. The overcurrent
protection device has
tripped. • Check the RC fault indicator on the switching cabinet.

The motor is running
irregularly or the ma-
chine is in fault mode. The machine is run-
ning at its limits;
the motor is drawing
11 A current;
the RC is regulating
the motor. • Reduce the rotation speed, and also the water quantity ac-
cordingly.

Too little water • When starting the machine, open the needle valve a little
more
• If necessary, switch off the machine from the main switch, and
then switch it on again after approx. 30 seconds (reset).

Material too rigid • Never open the device during operation
• If necessary, switch off the machine from the main switch, and
then switch it on again after approx. 30 seconds (reset).
Excessively high deliv-
ery pressure • Reduce hose length
• If necessary, switch off the machine from the main switch, and
then switch it on again after approx. 30 seconds (reset).
Only water comes out
of the mixing pipe
outlet The mixing coil is not
connected to the
rotor/stator. • Check if the mixing pipe is mounted properly.
• Check that the mixing coil is connected to the rotor/stator. Machine
