Error or Warning Code&No Cause Remedy
Error: 01
The software and hardware are not
compatible
Request customer service.
Error: 02 Hardware error Request customer service.
Error: 03 The motor is not connected Request customer service.
Error: 04 Motor temperature sensor error Request customer service.
Error: 05 Software error Request customer service.
Error: 06 Hardware error Request customer service.
Error: Temp Motor
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.
Error: Temp Contr
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.
Error: Voltage 5 voltage warnings within 24 hours
- Check the input voltage if it is
between the limits.
- Wait until the error state ends.
Error: Curr. high The pump draws too much current Wait until the error state ends.
Error: Service 5 any kind of errors within 24 hours Request customer service
Error: FOC Error
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.
Error: Blocked
Locked shaft due to the contamination
around the rotor
Wait until the error state ends.
Warning: Volt.Hi. High voltage from the power supply
Measure the mains voltages to check
whether it is between the limits
Warning: Volt.Low Low voltage from the power supply
Measure the mains voltages to check
whether it is between the limits
Warning: Rev. Flow
Motor is forced with a reverse rotation
flow
