Common water softener repairs include cleaning brine tanks, resin beds or resin tank injectors and adding more salt to the tank. Replacing brine lines and replacing filters are also common repairs.
Some water softener problems stem from simple issues such as too little salt in the tank. To check the salt levels, give the tank a quick flush and check the remaining salt levels. If they look low, add more salt before replenishing the water.
Many water softener problems stem from a dirty device. In most of these cases, cleaning all or some of the parts fixes the issue. Before cleaning out any parts, drain the wastewater from the softener by turning the manual regeneration knob, and then turn off the water source. Then, give the injector and its screen a good clean.
To clean a brine tank, look for any visible crusting. Use a stick to break up any crusting and remove it from the tank. Vacuum up dust and chalky residue, and then wash out the tank with soapy water.
Resin beds can often get clogged when water contains a lot of iron. To clean out the resin bed, wash the tank out with an iron-removal product such as Iron-Out. Add the product as directed on the label, and then flush it through the system.
To clean out a clogged resin tank injector, run the device through its manual regeneration cycle, remove the caps on the head and clean the injector and its screen manually.
Sometimes, water softener problems can require more serious repairs. If the brine lines look damaged or broken, remove them and replace them. If the filters are clogged with iron or residue, replace these to get the water flowing again. If the motor is faulty or damaged, consult a professional to fix it.
