What to do if MAC3 HydroController HCW-MM Standard Inverter shows 'No water'?
- N
  Nicholas JohnsonAug 17, 2025
  If the MAC3 Inverter displays a 'No water' error, it indicates a lack of water. The system automatically attempts to reset, but if these attempts fail, the system may become permanently blocked. First, ensure there is water available. For the HCW model, inspect the check valve. Reset the pump priming function and ensure the filter isn't blocked. If the problem persists, disconnect and then reconnect the power supply.

  If your MAC3 Inverter displays 'ShortC. f-f-gnd', it means a Phase-Phase or Phase-Ground short circuit has been detected. The system automatically attempts to resolve this, but if it fails multiple times, it will lock. To fix this, eliminate the cause of the short circuit, verify the motor's absorption, and try power cycling the device.

  If the MAC3 Inverter shows 'High temperature', it means the water temperature is above 75°C. This will automatically reset when the temperature drops below 60°C. Ensure the incoming water temperature is within the product specifications. For the HCA model, check the cooling fan's functionality and restore the correct pump priming action.

How to fix Imax Fault on MAC3 HydroController HCW-MM Standard Inverter?
- D
  Diana MooreAug 27, 2025
  If the MAC3 Inverter displays 'Imax Fault', it signifies an overcurrent in the pump. Check the current measurement output parameter to "LoadCurrent " and set the proper parameter “Max.MotorCurrent ". Also, verify that the pump is used under the conditions prescribed by its manufacturer and ensure there are no friction or locking issues with the impeller.

What does Low CosPhi mean on MAC3 Inverter?
- K
  Katrina MillerSep 7, 2025
  If the MAC3 Inverter displays 'Low CosPhi', the inverter detects a lower cosphi value than the value set at parameter COSPHI Min. Check for water presence. Set the value at parameter Cosphi Min Offset, to determine the correct value of COSPHI Min.
