7360867 PWA Circuit Board For Northstar And EcoPure
Best for upgrading older North Star and EcoPure softeners when the control panel becomes erratic or unresponsive. This replacement Electronic Control Board (PWA) is designed for compatibility with NSC22, NSC31, EPHS, EP31, EP42, and similar units. It aims to fix issues such as hardness detection errors and program failures without a full system replacement. The board uses premium components to resist voltage fluctuations and corrosion, helping extend the lifespan of the softener and reduce recurring repair costs.
Who this is for: Homeowners with North Star or EcoPure systems showing panel errors, unresponsive controls, or occasional software faults. It’s a practical fix for those seeking a long-term repair rather than buying a new unit.
Limitations to note: Confirm exact model compatibility prior to purchase; some variants may require additional wiring or mounting alignment to match the original interface.
V3108 Circuit Board For Clack WS1/WS1.25 Systems
Best for Clack WS1 and WS1.25 control valves with five horizontal buttons. This replacement board supports cross-reference to multiple OEM part numbers (V3108, C3108, C3108-09BOARD, C3108-11BOARD, CL3108-09BOARD). It is not compatible with three-button or Time Clock (TC) versions. Its plug‑and‑play design allows a tool-free swap by disconnecting the wire harness, clipping in the new board, and reconnecting cables. It serves as the core control for the whole softening cycle and is ideal for repairing faulty Clack-based systems while preserving the rest of the hardware.
Who this is for: Homeowners with Clack WS1 valves seeking a straightforward, compatible replacement board to restore full cycle control without redesigning their plumbing.
Caution: Verify your control head’s button configuration (five horizontal buttons) before purchasing to ensure compatibility.
Hoypeyfiy 5600 Timer Control Valve
Best for residential, whole-house installations requiring a reliable 5600 timer-based control valve. This 12-day timer head replacement supports standard 9″-11″ resin tanks and is designed to manage regeneration cycles and backwash operations to maintain softening performance. It fits typical residential systems and offers a straightforward, modular replacement path when the timer head wears or fails.
Who this is for: Households that rely on a classic timer-driven softener and want a simple, cost-effective upgrade to maintain regular regeneration schedules.
Limitation to consider: Confirm resin tank diameter and thread compatibility (9″–11″ fine thread) to ensure proper fitment with your existing tank.
Fleck 5600SXT Digital Control Valve
Best for robust, modern digital control with a built-in display. This 110V, digital control valve provides a user-friendly interface to monitor and adjust softening settings, including cycle timing and salt use. Its durable PP construction offers resistance to wear and everyday exposure, making it a solid upgrade for households needing clearer operation and easier maintenance over traditional mechanical heads.
Who this is for: Homeowners wanting a more intuitive, adjustable control valve with a display to simplify monitoring and tuning of the softening process.
Limitations to note: Some rental or retrofit projects may require mounting or connector adjustments to align with existing hardware.
7360867 Water Softeners Electronic Circuit Board
Best for North Star models in addition to EcoPure units. This replacement circuit board matches the 7360867 part number and features an identical interface design and mounting structure to the original, minimizing the risk of misfit or additional drilling. It helps prevent issues like excessively hard water output and unexpected shutdowns caused by control board failures.
Who this is for: Homeowners with North Star NSC22/NSC31 or EcoPure EP-series softeners needing a direct swap to restore reliable operation.
Limitations to note: Ensure your model variant aligns with the North Star or EcoPure family to guarantee full compatibility.
Buying Guide: Key Purchase Considerations
- System compatibility: Match the control board or valve to your specific softener brand and model (Clack WS1, Fleck 5600SXT, North Star, EcoPure, etc.).
- Interface and mounting: Look for identical mounting patterns and interface design to avoid modifications to the housing or wiring harness.
- Replacement scope: Decide whether you need a full control board, a timer head, or a complete valve assembly based on the symptoms (unresponsive display, failed regeneration, incorrect hardness output).
- Ease of installation: Favor plug-and-play designs that require minimal tools and wiring changes for quicker repairs.
- Durability and materials: Choose parts with corrosion-resistant components and robust housings to extend life in water exposure environments.
- Tank compatibility: For timer heads and valves, confirm resin tank diameter and thread type (commonly 9″-11″ for standard residential systems) to ensure proper fit.
- Future repairs: Consider parts with broader compatibility if you plan to upgrade to newer control heads in the future.
Frequently Asked Questions
- What does a water softener control panel do?
It manages the softening cycle, regeneration timing, and salt usage to ensure consistent water softness and system efficiency. - When should I replace the control head instead of the entire unit?
If the unit shows persistent unresponsiveness, mis-timed regenerations, or incorrect hardness output, a control head or board replacement is often cost-effective. - Is a plug-and-play replacement easy for beginners?
Many options are designed for straightforward installation, but always disconnect power and follow manufacturer wiring diagrams carefully. - How do I know which part fits my model?
Check the product compatibility list and confirm your model’s head type, valve type, and number of buttons in the control panel. - Can these parts affect water quality if installed incorrectly?
Yes. Improper wiring or incompatible parts can cause improper regeneration and hardness levels. If in doubt, seek professional help. - Do I need professional service for replacement?
In most cases replacements are DIY-friendly, but complex wiring or internal plumbing modifications may require a licensed technician.
