Fault finding
For information on the different indicator signals and how to address them, please refer to paragraph
Function and indicator signals.
Symptom
Probable cause
Action
Although the pump
is running, the
machine is never
emptied.
The water hose can be
clogged/squeezed or lead
higher than 3,5 meters, the
maximum elevation height
of the pump.
The turbine/Kombi machine
power cable is not
connected to the machine
but to a separate power
outlet. Therefore, it does
not stop and the
underpressure prevents the
pump from functioning.
If necessary, clean the hose and make sure
the elevation is not higher than 3.5 meters.
If not done already, connect the
turbine/Kombi machine power cable to the
machine so that it is stopped when the pump
is activated.
The pump does not
start or makes
noise.
Heavily dirty or failing pump
and/or sensor/float switch.
Clean the machine in accordance with the
instructions of this manual.
Verify that the installation is correct
If the problem(s) still remain, contact your
retailed for repair.
It is not possible to
start the pump
manually, the WS4
ES does not react to
the manual pump
switch.
There is no water in the
WS4 ES.
If there is water in the
machine and the pump still
does not start, either the
sensor or the pump is
failing.
If the WS4 ES does not detect any water, the
pump will not start.
Try to clean the machine. If that does not
help, contact your retailed for repair.
