High temperature at the stator
windings due to the motor overload
and/or high winding temperature
- Check the water temperature if it is
between the limits.
- Wait until the error state ends.
High temperature at the stator
windings due to the motor overload
and/or high winding temperature
- Check the ambient temperature and
enhance the ambient ventilation.
- Check the water temperature if it is
between the limits.
- Wait until the error state ends.
5 voltage warnings within 24 hours
- Check the input voltage if it is
between the limits.
- Wait until the error state ends.
The pump draws too much current
Wait until the error state ends.
5 any kind of errors within 24 hours
The stator and shaft do not rotate at
synchronous speed
- Check the directions of the arrow on
the housing and the flow of the water
- Wait until the error state ends.
Locked shaft due to the contamination
around the rotor
Wait until the error state ends.
High voltage from the power supply
Measure the mains voltages to check
whether it is between the limits
Low voltage from the power supply
Measure the mains voltages to check
whether it is between the limits
Motor is forced with a reverse rotation
flow
