Error description
Possible cause and solution
1
Low load detected
There is no medium in the pump. Check if
there is medium in the system.
2
Overloading of motor
Excessive current load or blocked rotor. If the
issue persists, check if the rotor is spinning
freely.
3
Motor too hot
Motor has exceeded allowed temperature and
is now stopped to cool down. Once cooled, it
will automatically restart.
4
Electronics error
An electronics error was detected. The pump
can still operate, but needs servicing.
5
Engine/stator failure
There could be an interruption in the engine
winding. Pump needs servicing.
