Possible Causes
Stuck brine refill valve, Leaking brine valve seat, Blocked brine line preventing proper air check closure, Incorrect refill time setting
How to Fix / Troubleshooting
Safety first: Disconnect power and close inlet valve. Mop up any spilled brine; it can be slippery and corrosive.
- Check float/air check: Remove the brine well cap and inspect the float/air check assembly. Clean and ensure it moves freely and seals when raised.
- Inspect brine valve: Disassemble the brine refill valve in the BWT head and check for debris on the seat. Clean and reassemble.
- Verify settings: Confirm that the brine refill time in the controller matches the BWT specification for your salt and hardness. Reduce if set too high.
- Test cycle: After reassembly, run a manual regeneration while observing the brine tank. Ensure the water stops rising at the correct level.
Persistent overfilling may require replacement of the brine valve or float assembly.
