Understanding WHES40 Water Level Issues

The Whirlpool WHES40 water softener experiencing a brine tank full of water is a common issue that indicates potential problems with the system's regeneration cycle or internal components. Normally, the brine tank should only contain a small amount of water (typically 4-6 inches) above the salt level to create brine solution. When the tank remains full of water, it suggests the system isn't properly completing its regeneration process or there's a malfunction in the control mechanism.

Common Causes of Brine Tank Overfilling:

• Clogged Injector Nozzle: Debris or mineral buildup blocking the venturi assembly
• Stuck Brine Valve: Mechanical failure preventing proper brine draw during regeneration
• Control Head Malfunction: Electronic issues with the timer or control board
• Drain Line Problems: Kinked, clogged, or frozen drain line preventing proper drainage
• Salt Bridge Formation: Hardened salt crust preventing water from reaching lower levels
• Venturi Screen Clog: Blocked screen in the venturi assembly restricting water flow
• Float Assembly Issues: Malfunctioning brine tank float valve

Normal vs. Abnormal Water Levels:

Under normal operation, the WHES40 brine tank should maintain water levels approximately 4-6 inches above the salt bed. This water is used to create brine solution for regeneration. The water level should decrease during the brine draw cycle as the solution is pulled into the mineral tank. If the water level remains consistently high or the tank overflows, this indicates a system malfunction. The control head should initiate a regeneration cycle approximately every 7-14 days depending on water usage, during which the brine tank should fill, then empty as brine is drawn into the system.
