Wilo · Control EC-Fire Pump
This indicates that either the pump has drawn too much current (overcurrent) or too little current (minimum current), triggering the internal monitoring or motor protection switch. This could be due to a blockage or a fault in the supply line.
Click steps to track your progress.
Check the pump for any obstructions or blockages.
Inspect the supply line for damage or faults.
If the motor protection switch tripped (for versions > 12A), reset it.
Acknowledge the fault on the switchgear after resolving the cause.
