In the case of malfunction, you should first of all check whether it was caused by
an operating error or some other reason which cannot be attributed to a defect of
the device - for instance a power failure.
The list below shows some possible malfunctions of the device, possible causes
and tips on their elimination. All the measures referred to may only be carried out
with the pump being separated from the electrical mains. If you yourself feel una-
ble to eliminate any of these malfunctions, please contact the customer service
department or your point of sales. Any repair beyond the scope specified below
must only be performed by qualified staff. Please bear in mind that all warranty
claims will become void in the case of damage caused by inappropriate repair at-
tempts, and that we decline any liability for any ensuing damage.

Possible Cause
No current.
Thermal motor protection feature has trig-
gered.
The capacitor is defective.
The motor shaft is jamming.
The electronic pump control is defective.
The anti-dry-running feature is activated
(red "Fehler" (Error) indicator lights up).
The pump housing is not filled with liquid.
Air penetrates into the intake line.
Suction height and/or discharge height too
great.
The difference in height between the pump
and the point of withdrawal, limited to max.
16 m by the pre-set value (Cut In pressure
1,6 bar), has been exceeded.
The electrical supply does not correspond
to the information given on the type plate.
Pump or intake line are blocked by solids.
Liquid is too viscous.
Temperature of liquid or environment is too
high.

Elimination
1. Please use a device complying with GS (German
technical supervisory authority) to check for the
presence of voltage (safety information to be ob-
served!). Please verify the correct position of the
plug.
2. Separate the pump from the electrical mains, al-
low the system to cool down, eliminate cause.
3. Please contact the customer service department.
4. Check the cause; eliminate the reason for the
jamming of the pump.
5. Please contact the customer service department.
6. Refer to section 2.2 and 2.3 and 4.2
1. Fill the pump housing with liquid (please refer to
"Putting into operation" section).
2. Check to make sure that:
a) the connection points of the intake line are tight;
b) the inlet opening of the intake line including the
check valve (non-return valve) are immersed into
the liquids being discharged;
c) the check valve (non-return valve) with the filter is
tight and not jammed;
d) no siphons (i.e. permanently liquid-filled loops),
kinks, counter-slopes or narrow spots are present
along the intake lines.
3. Change the arrangement of the installation so that
the suction height and/or discharge height will not
exceed the max. value.
4. The switch-on pressure of the electronic pump
control is to be increased., see chapter 8.4.
1. Please use a device complying with GS (German
technical supervisory authority) to check the vol-
tage of the lines of the connection cord (safety in-
formation to be observed!).
2. Remove possible congestion.
3. Pump may not be suitable for this liquid. If feasi-
ble, the liquid should be thinned.
4. Make sure that the temperature of the liquid being
pumped and the environment do not exceed the
max. admissible values.
