Temperature / Conductivity Sensor Fault (if equipped)
Symptom
Brine tank overflows or fills with water up to the top.
Brine Tank Overfill
Symptom
Softener appears to be stuck in regeneration and does not return to service.
Regeneration Cycle Hang / Incomplete Indexing
Symptom
Softener causes noticeable pressure drop or low flow at faucets when in service.
Flow Restriction Through Softener
Symptom
Softener causes salty taste in household water after regeneration.
Residual Brine in Service Water
Symptom
Softener does not regenerate at all; no noise or movement at scheduled time and water becomes hard.
No Regeneration / Control Not Initiating Cycle
Symptom
Softener does not use any salt; salt level in brine tank never drops.
No Brine Draw / Salt Not Dissolving
Symptom
Softener emits a rotten egg or foul odor from treated water.
Bacterial Growth or Sulfur Contamination
Symptom
Softener makes loud clicking, grinding, or humming noises during regeneration.
Noisy Drive Motor or Gear Train
Symptom
Softener regenerates too frequently, wasting salt and water.
Over-Regeneration / Oversized Reserve
Symptom
Softener’s brine tank forms large solid masses of salt (salt mushing) and stops working properly.
Salt Mushing / Compaction
Symptom
Softener’s bypass valve is difficult to turn or stuck in one position.
Stiff or Seized Bypass Valve
Symptom
Softener’s control head or electronics show signs of corrosion or white powdery deposits.
Salt-Induced Corrosion of Electronics
Symptom
Softener’s display is blank or flickering; unit appears dead intermittently.
Intermittent Power / Display Failure
Symptom
Softener’s drain line occasionally backs up or overflows at the drain point.
Drain Line Restriction or Improper Air Gap
Symptom
Softener’s resin tank makes knocking or banging noises when water is turned on or off.
Water Hammer / Hydraulic Shock
Symptom
Water remains hard even after recent regeneration; soap does not lather and scale forms on fixtures.
Exhausted or Fouled Resin Bed
Symptom
Water softener drain line continuously runs water even when not regenerating.
Valve Not Sealing / Continuous Drain
Symptom
Water softener drain line discharges rusty or dirty water for extended periods during regeneration.
Excessive Sediment / Iron Discharge
Symptom
Water softener is leaking from around the control valve or tank connections.
External Water Leak at Valve or Plumbing
