What to do if the red LED indicator illuminates with “Error” and “MOTOR” flashing on my ProMinent Sigma 2 S2Ca Water Pump?

  If the red LED indicator illuminates and the display shows “Error” and “MOTOR” flashing on your ProMinent Water Pump, this could be due to several reasons. First, high back pressure might be preventing the motor from working correctly; try reducing the back pressure and then press the [P] key to reset. Second, the motor may have overheated; ensure the ambient temperature is no more than 40 °C, allow the motor to cool down, and then press the [P] key. If these steps don't resolve the issue, there may be other motor faults, in such case press the [P] key to reset function.

  If the red LED indicator illuminates and the identifiers “Error” and “FLOW” flash on the display of your ProMinent Water Pump, it could be due to a couple of reasons. First, the dosing monitor might not be correctly connected, ensure it is properly connected and then press the [P] key. Second, the dosing monitor may have reported more defective strokes than set in the “FLOW” menu. Press the [P] key and then investigate to find and clear the underlying cause.

What does it mean if the red LED indicator illuminates with “Error” and “TEMPERATURE” flashing on my ProMinent Sigma 2 S2Ca?

  If the red LED indicator illuminates and the identifiers “Error” and “TEMPERATURE” flash on the display of your ProMinent Water Pump, it means the temperature inside the pump housing is too high. This could be due to a high outside temperature; ensure lower outside temperatures and allow the pump to cool, then press the [P] key to reset. Alternatively, it could be due to high pump power consumption; check the installation, change it if necessary, allow the pump to cool, and then press the [P] key to reset.
