BASC080341 | Printed Circuit Board Clearwater
Replacement Control Board for Clearwater C140S Salt Chlorinator
This BASC080341 Printed Circuit Board is a genuine replacement component for the Clearwater Salt Chlorinator C140S model. As the central control unit for your salt chlorination system, this PCB manages the electrolysis process that converts salt into chlorine, maintaining clean and sanitized spa water automatically.
What is This Circuit Board?
This printed circuit board is the electronic control centre of the Clearwater C140S salt chlorinator system. It regulates the electrical current sent to the salt cell, monitors system performance, and controls the chlorine generation process. When this board functions properly, your spa maintains consistent sanitizer levels without manual chemical addition.
Understanding Salt Chlorinator Systems
Salt chlorinators offer an alternative to traditional chemical dosing by generating chlorine directly from dissolved salt in your spa water. The PCB controls this electrolysis process, determining when and how much chlorine to produce based on your spa’s requirements. This automation provides consistent water quality while reducing the need for handling and storing harsh chemicals.
Key Functions
Chlorine Production Control
Regulates the power supplied to the salt cell, controlling the rate of chlorine generation based on system settings.
System Monitoring
Tracks operational parameters including cell performance, water flow, and system status to ensure optimal function.
Safety Management
Monitors for fault conditions such as low salt levels, inadequate water flow, or cell issues, protecting both the equipment and users.
User Interface Connection
Interfaces with the control panel, allowing you to adjust settings and view system status.
Common Reasons for Replacement
PCBs may require replacement due to:
- Power surge or lightning strike damage
- Component failure from age or moisture exposure
- Corrosion from humid spa environment
- Manufacturing defect in original board
- Physical damage to board components
Signs Your PCB Needs Replacement
- Salt chlorinator system completely non-responsive
- Error codes or fault indicators that won’t clear
- Intermittent operation or random shutdowns
- No chlorine production despite proper salt levels
- Display problems or erratic readings
- System was functioning before sudden failure
Compatibility Information
Specific Model Compatibility:
This PCB is designed specifically for the Clearwater Salt Chlorinator C140S model. Using this board with other systems may result in improper operation or damage.
Before Ordering:

- All connections are secure and corrosion-free
- Fuses or breakers haven’t tripped
- Salt levels are within recommended range
- Water flow is adequate
- Salt cell isn’t damaged or heavily scaled
Why Salt Chlorination?
Salt chlorinator systems like the Clearwater C140S offer several advantages:
- Consistent chlorine levels without daily testing
- Reduced chemical handling and storage
- Softer water feel compared to traditional chlorine
- Lower long-term chemical costs
- Automated sanitization process
The PCB is critical to this automation, making proper function essential for system performance.
Note: Always verify model compatibility before purchasing replacement control boards. Installation of electronic components should be performed by qualified individuals familiar with spa electrical systems. Improper installation can result in equipment damage or safety hazards.
