LED Faults Cause Remedy
Lights up
red Blocking Rotor blocked Activate manual
restart or contact
customer service
Contacting/ winding Winding defective
Flashes
red Under/overvoltage Power supply too low/high on mains
side
Check mains voltage
and operating con-
ditions, and request
customer service
Excessive
module temperature Module interiour too warm
Short-circuit Motor current too high
Flashes
red/
green
Generator operation
Water is flowing through the pump
hydraulics, but there is no mains vol-
tage at the pump
Check the mains
voltage, water
quantity/pressure
and the ambient
conditions
Dry run Air in the pump
Overload
Sluggish motor, pump is operated
outside of its specifications (e.g. high
module temperature). The speed is
lower than during normal operation
