After remedy of the failure reason it is necessary to switch on the Hydrovar-
Please contact your distributor if the same failure occurs more often. Give a detailed
description of the error, the failure code and the serial number of the Hydrovar-
Watercooled.

Failure reason
6
Under Voltage –
Supply voltage is too low
6
Processor Error
Software failure
Low Water
6
Output pressure is below
25% of the required
pressure
Sensor Error
Over-Temperature Motor/
6
Over-Temperature Drive
PTC of the motor has
detected over-temperature
or the Hydrovar-
Watercooled
has reached
its maximum temperature.
6
Over current /
Short circuit
Overload
Output current to te motor
is too high due to too high
nominal power of the
motor or short circuit of 2
phases of the motor or the
motor cable.
6
Over voltage
Supply voltage is too high
or spikes on the supply
side.
Dark
Possible solution
Check the cable and the terminals on
the supply side of the Hydrovar
Check the ground and earth connection
and the cabling that no signal cable is
running in parallel with a power cable
The incoming water flow rate or the
suction pressure is too low
Check cable connection of the internal
sensor or changing of the complete
pressure measurement device (contact
your service partner)
Ambient temperature is too high or
cooling of the motor is not efficient.
Clean the cover and the motor fan and
read the manual of the motor.
Temperature of the handled liquid is too
high or no flow through the Hydrovar-
Watercooled
for efficient cooling.
Check the power consumption of the
motor and the working point of the pump
if they do not exceed the max. output
power of the Hydrovar-
nominal power -
Reduce the flow rate.
Check the connection to the motor.
Pump is blocked or tight due to solid
parts inside the pump
Check the supply voltage level and all
connections -
If there are spikes on the supply line,
use special filters on the input side
