Flow rate too high Check the pump data and default values
and correct if necessary
Turn-to-turn fault in the motor Check, if necessary replace motor or have it
repaired
Mains voltage: A phase is missing Check the fuses, cables and connections
Motor protection switch triggers Non-return valve defective Check and replace the non-return valve if
necessary
Flow rate too high Check the pump data and default values
and correct if necessary
Contactor defective Check it and replace it if necessary
Turn-to-turn fault in the motor Check, if necessary replace motor or have it
repaired
Mains voltage: A phase is missing Check the fuses, cables and connections
Pump generates no or insufficient
power Major fluctuations of the inlet pressure Check the inlet pressure and take measures
to stabilise the supply pressure if necessary
(e.g. pressure reducers)
Inlet pipe clogged or shut off Check the inlet pipe and, if necessary,
remove the clogging or open the shut-off
valve
Nominal diameter of the inlet pipe too
small Check the inlet pipe and increase the cross-
section of the inlet pipe if necessary
Inlet pipe installed incorrectly Check the inlet pipe and change the pipe
routing if necessary
Air in the inlet Check and, if necessary, seal the piping and
vent the pumps
Impellers clogged Check the pump and replace it or have it
repaired if necessary
Non-return valve leaking Check and replace the seal or non-return
valve if necessary
Non-return valve clogged Check and remove the clogging or replace
the non-return valve if necessary
Gate valve in the system closed or not
sufficiently open Check, fully open the shut-off valve
Low-water level switch has triggered Check the inlet pressure
Pump generates no or insufficient
power Incorrect direction of rotation of the
motor Check the direction of rotation and repair or
replace the frequency converter module if
necessary
Turn-to-turn fault in the motor Check, if necessary replace motor or have it
repaired
Dry-running protection switches off
although water is present Major fluctuations of the inlet pressure Check the inlet pressure and take measures
to stabilise the supply pressure if necessary
(e.g. pressure reducers)
Nominal diameter of the inlet pipe too
small Check the inlet pipe and increase the cross-
section of the inlet pipe if necessary
Inlet pipe installed incorrectly Check the inlet pipe and change the pipe
routing if necessary
Flow rate too high Check the pump data and default values
and correct if necessary
Electrodes connected incorrectly or
supply pressure switch set incorrectly Check installation and setting and correct
as required
Low-water level switch or pressure
sensor on the inlet side defective Check and, if necessary, replace the low-
water level switch or pressure sensor
Dry-running protection does not
switch off in spite of low water Electrodes connected incorrectly or
supply pressure switch set incorrectly Check installation and setting and correct
as required
Low-water level switch or pressure
sensor on the inlet side defective Check and, if necessary, replace the low-
water level switch or pressure sensor
