A fault code is displayed on the Varipump controller

The controller can display a fault code if the pump develops a problem. Download the fault code troubleshooting guide at the bottom of this page to identify the issue.

If your Varipump was manufactured before 2021, the fault codes are:

E01 = Pump is out of water > The pump is working without water.

E02 = Over current > Abnormal load over current protection. Please pull out the power plug and re-plug again.

E03 = Default phase > Bad contact or loose connection in the motor.

E04 = Issue with power cable connecting pump to the control box > Check the cable for signs of visible damage. Or there maybe a loose connection inside the control box. Disconnect the pump from the mains, unscrew the control box and check the connections. If the connections are fitted and pump still does not work, the control box may need changing.

E05 = Impeller stuck > Rotation clogging protection, if the pump still not working after restart for three times, please re-plug the power. Or clean the impeller (refer to manual).

E06 = Over voltage > Over voltage protection when the working voltage is higher than the rated voltage.

E07 = Under voltage > Low voltage protection when the working voltage is lower than the rated voltage.

HHH = Reduced Mains Power Supply Following Power Cut > If the code HHH displays on the control box, it means there is not enough power being supplied to the pump following a power cut. It is likely that there has been mains power cut in your area and when the energy company have restored power the mains supply is not running at full power (e.g. 205 Volts instead of 230 Volts). If you wait a few hours the mains supply will return to normal (230 Volts) and the pump will re-start. This fault code does not mean the pump is faulty.

 

If your Varipump was manufactured after 2021, the fault codes are:

E01 = Low water protection > Ensure the pump is primed with water.

E02 = Motor out of sync > Bad contact or loose connection in the motor. Please pull out the power plug and re-plug again.

E03 = Over voltage protection > Check and fix the power source in accordance with the correct voltage supply.

E04 = Low voltage protection > Check and fix the power source in accordance with the correct voltage supply.

E05 = Impeller blocked > Check and make sure the rotor / impeller is not blocked by any dirt. Disconnect from the mains power and wash and clean the rotor / impeller part. Wait until the display on the LCD is off. Re-connect the power and re-start the pump.

E06 = Over current protection > Disconnect from the mains power. Wait until the display on the LCD is off.
Re-connect the power and re-start the pump.

HHH = Reduced Mains Power Supply Following Power Cut > If the code HHH displays on the control box, it means there is not enough power being supplied to the pump following a power cut. It is likely that there has been mains power cut in your area and when the energy company have restored power the mains supply is not running at full power (e.g. 205 Volts instead of 230 Volts).
