Clearwater softener display is blank or unresponsive, but outlet has power.

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 AC adapter, Loose low-voltage connector, Blown internal fuse, Failed display module or main board

Safety first: Unplug the adapter before opening the control housing.

Verify adapter output: Use a multimeter to confirm the Clearwater adapter outputs the correct voltage.
Check connections: Ensure the low-voltage plug is fully seated on the control board.
Inspect internal fuse: Some Clearwater boards have a small fuse; replace only with the same type and rating if blown.
Test with new adapter: Try a known-good Clearwater adapter if available.

If the display remains dead, the display module or main control board must be replaced.
