Whirlpool Softener Parts
Whirlpool water softener parts are available at Lowe's, Lowe's.com, and Amazon. The valve design is EcoWater proprietary — the same parent as WaterBoss, which means some component overlap but not direct compatibility between the two lines. Key replacement parts:
| Part | Life | Cost |
|---|---|---|
| Brine valve/float assembly | 5–10 years | $20–$40 |
| Valve piston kit | 8–12 years | $25–$50 |
| Control module (PCB) | 10–15 years | $90–$150 |
| Resin (1 cu ft) | 10–15 years | $45–$80 |
Whirlpool Salt Capacity and Refill Schedule
The WHES40E brine tank holds approximately 150 lbs of pellet salt. At a typical household consumption of 6–10 lbs of salt per regeneration cycle and 1–2 regeneration cycles per week, a full brine tank lasts 8–12 weeks before refilling. Whirlpool recommends checking salt level monthly and refilling when the tank drops below 1/3 full. Do not allow the brine tank to run completely dry — an empty brine tank causes the softener to regenerate with fresh water instead of concentrated brine, leaving the resin bed with reduced capacity until a brine-present regeneration cycle can recharge it.
