Softener continuously drains water even when not in regeneration; a steady stream is heard at the drain.

Safety first: Immediately place the softener in bypass to stop water waste. Unplug the unit before disassembly.

• Confirm drain flow: Check the drain line to verify continuous flow when the unit should be in service.
• Inspect rotor and seal kit: Remove the rotor and seal kit and look for debris, resin beads, or damage preventing a tight seal in the service position. Clean or replace as needed.
• Check valve body: Inspect the valve body for cracks or erosion around the drain port. Replace the valve body if damaged.
• Control board test: After mechanical repairs, restore power and observe whether the unit immediately energizes the motor into a backwash position. If the board repeatedly commands drain flow without reason, replace the electronic control board.
