Wilo Control EC-Fire Pump
14 fault codes documented
Alternating red and green flashes — Pump failure detected
This visual signal indicates that one of the connected pumps has failed. The system will automatically attempt to switch to a functional pump (standby pump).
Display shows error code — Specific fault information
The LCD display shows an alphanumeric code indicating a specific fault within the system. This allows for precise diagnosis and troubleshooting.
E006 — Rotating field error
This error indicates an issue with the electrical connection or the direction of the rotating field supplied to the pump. The switchgear is set for a specific rotation direction.
E022.x — Insulation fault
The insulation monitoring device has detected a fault. This means there might be an issue with the electrical insulation between the pump's conductors and the earth potential.
E040 — Pressure/volume flow sensor fault
This error means the pressure or volume flow sensor is not working correctly. It could be defective or have lost its electrical connection.
E062 — Water shortage detected
The protection against low water level has been triggered, meaning the pump has detected insufficient water to operate safely. The pumps will restart automatically once water is available.
E080.x — Pump fault (Overcurrent or minimum current)
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.
E090 — Plausibility error
The system has detected an implausible situation where the pump started but no volume flow was detected within 10 seconds. This suggests an issue with the pump's delivery function or the flow sensor.
Flashing fault LED — Fault requiring delayed action
This indicates a fault that may lead to a system shutdown after a set time has elapsed. The fault signal LED will flash, and the error code will alternate with the main screen display.
Flashing pump status symbol — Fault on a connected pump
A flashing status symbol on the main screen indicates that there is a fault specifically related to one of the connected pumps. The exact nature of the fault should be visible on the display.
Green LED lit — Pump(s) are operating in automatic mode
The green LED indicates that one or more pumps are currently running in automatic mode. This is a normal operating status.
Red LED lit — General fault signal
The collective fault signal LED is lit, indicating that a fault has been detected within the system. This often accompanies an acoustic alarm.
Red collective fault LED lit and buzzer sounds — System fault detected
A serious fault has occurred in the system. The red collective fault LED will light up, and an acoustic alarm will sound via the internal buzzer. The specific error code will alternate with the main screen display.
Flashing 'off' indicator, then 'Reset' indicator, then fault acknowledged — Resetting faults
This sequence describes the procedure for acknowledging and clearing faults from the system. It involves navigating menus to reset the fault status.
