How to Fix / Troubleshooting
Safety first: Only work on electrical connections if you are competent. Otherwise, contact an electrician.
- Check outlet and spur: Verify that the wall socket or fused spur is live and the switch is on. Replace the fuse with the correct rating if blown.
- Inspect power lead: Ensure the power cable is firmly plugged into the softener and not damaged.
- Test adaptor/transformer: If accessible, measure the output voltage of the transformer with a multimeter and compare to the rating label.
- PCB inspection: If power is present at the board but the display is dead, the PCB may have failed and require replacement.
