How To Determine If A Fully Automatic Water Softener Needs Repair?

 Troubleshooting methods for fully automatic water softeners

Based on the equipment's operating status and fault symptoms, the need for maintenance can be determined from the following three aspects:

I. Abnormal effluent water quality

Phenomenon : Water hardness exceeds the standard (Test strip detection > 0.05 mmol/L), the water softening effect disappears.
 Causes and Repairs :

Resin failure Replace after 3-5 years of use; if not yet at the end of its lifespan, it can be revived by acid washing (soaking in 5%-10% hydrochloric acid solution).

Insufficient amount of regenerated salt Check the salt level in the salt tank (it should be more than 1/2 full), and replace it with industrial salt with a purity of ≥99%.

If the hardness of the influent exceeds the standard, it is necessary to replace it with equipment with a larger treatment capacity or install pretreatment.

II. The equipment cannot automatically regenerate.

Phenomenon : Regeneration fails to start or the process is disordered when the time comes.
 Causes and Repairs :

Control head failure Check the power supply (220V stable), press and hold the reset button to restart; if ineffective, replace the control head.

Pipe blockage: Clean the connecting pipes from the salt tank to the resin tank and the wastewater pipes to remove salt scale or impurities.

Time/flow rate setting error: Reset the regeneration time (avoid peak water usage) or flow rate parameters.
3. Equipment leakage

Phenomenon : Water dripping or seeping from interfaces, valves, or tank parts.
Causes and Repairs :

Leaking at the interface: Check if the sealing gasket is aging, replace it and tighten the screws evenly.
Leaking valve: Clean impurities from the valve core, replace the sealing ring or valve body.

Tank cracks: Small cracks can be repaired with epoxy resin glue; large cracks or aging require replacement with a new tank.
