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.
