Step-by-Step Fix
Safety & Preparation
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- Firstly, lift the lid off your water softener's brine tank and visually inspect the salt level inside. If the salt is below the halfway mark or you can see the water level, carefully top it up with block or tablet salt, ensuring it doesn't overflow or jam the brine well.
- If you suspect a 'salt bridge' (a crust of salt forming a hard layer above the water), gently use a broom handle or a long stick to carefully break it up. Once broken, ensure the salt falls to the bottom of the tank and is fully dissolved in the water, as this allows the softener to draw brine effectively.
- Next, locate the control head or display panel on your water softener and check the current time, date, and any programmed settings. Verify that the hardness setting is correct for your area and that the regeneration schedule aligns with your household's water usage.
- Ensure the power cord is securely plugged into a working electrical socket and that there are no tripped circuit breakers; if the unit has a display, check it's illuminated. Then, manually initiate a regeneration cycle according to your softener's manual and observe if it starts and progresses through the stages, listening for the sound of water moving.
- If, after following these steps, your water softener continues to produce hard water or display error messages, it's time to call in a professional. Contact a qualified plumbing technician who specialises in water softeners to diagnose and repair more complex internal issues.
