How to Fix / Troubleshooting

Safety first: Disconnect power and close inlet/outlet valves. Relieve pressure via a downstream tap.

Remove control head cover: Expose the gear train and cam assembly in the Aquabion valve.
Inspect gears: Look for cracked, missing, or worn gear teeth. Replace the gear kit if any damage is found.
Check for debris: Inspect around the rotor and valve ports for foreign objects or scale that could cause binding. Clean carefully.
Test motor: With the cover off and power restored briefly, observe the valve drive motor during a manual regeneration. Replace the motor if it stalls or runs erratically.

Warning: Keep fingers and tools clear of moving gears when testing with power applied.

Aquabion softener is making loud clicking or grinding noises during regeneration.
