Part Description:
The 12 Volt Transformer (Power Cord) supplies low-voltage electrical power to WaterBoss, AquaMaster, and AquaMaster PRO water softeners. It connects the unit to a standard household electrical outlet and converts incoming voltage to a safe 12V output required to power the softener’s control board and motorized components.
Function & Importance:
Supplies consistent electrical current to run the electronic display and programming functions
Powers the drive motor that controls valve positioning during the regeneration cycle
Without power, the system cannot initiate or complete a regeneration cycle
Converts standard outlet voltage to 12V DC for safe, efficient operation
Common Signs of Issues:
Blank display indicating no power is reaching the control board
Without power, timed or demand-based regeneration will not occur
Intermittent Power or Resetting Clock could be due to a loose or damaged power cord connection
Buzzing or Warm Transformermay signal a failing transformer or internal short
Compatible Models:
WaterBoss 700, 900, and 950
AquaMaster 700, 900, and 950
AquaMaster PRO 5000, 5100, and 5500
Installation Tips:
Always use a grounded, protected outlet near the softener
Keep the cord clear of water, salt, and moving parts
Ensure the transformer plug fits securely into the softener’s power port
Plug directly into an outlet to avoid voltage drop or power interruptions
Why It Matters:
Without a working transformer, the water softener is effectively off—the system can’t display settings, track water usage, or regenerate properly. A reliable power supply ensures uninterrupted operation, protects your plumbing from hard water buildup, and maintains the efficiency and performance of your softener. It’s a small part with a big impact on the life and function of your system. Please call technical support first to ensure this is the correct part for the issue your softener may be experiencing 1-800-437-8993 (EST).
