Softener display is blank but unit still passes water

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed display module, Loose low-voltage connector, Blown internal fuse, Faulty power supply to UI

Safety: Unplug the unit before opening the control housing.

Check mains power: Confirm that the outlet has power and that any external switch is on.
Inspect internal fuse: Locate and check the low-voltage fuse on the control board. Replace only with the same type and rating.
Verify connectors: Reseat the low-voltage connector from the power supply to the display module.
Test display: If the board has indicator LEDs that are lit but the display is blank, the display module is likely faulty and should be replaced.
