Water2Buy Display / Power Loss to Control Only

Water2Buy softener display is blank but the 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 power connector, Blown internal fuse on PCB, Faulty power adapter

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

Check outlet and adapter: Confirm the outlet has power and test the adapter output with a multimeter.
Inspect DC jack and wiring: Ensure the adapter plug is fully inserted and that internal wiring to the PCB is intact.
Look for fuses: Some boards have a small fuse. Replace only with the same type and rating if blown.
Replace display/PCB: If power is present but the display remains blank, replace the control PCB or full head assembly.
