PCBs ,Expander Boards, Fuses and Splitters FAQs

  • What is a PCB in a hot tub?

    A PCB (Printed Circuit Board) is the brain of your hot tub, controlling essential functions like heating, filtration, and jet operation. If your hot tub is experiencing electrical issues, heating failures, or pump malfunctions, a faulty PCB may be the cause.

  • What’s the difference between a PCB and an expander board?

    A PCB (Printed Circuit Board) is the main control board that manages all electrical functions in a hot tub. The Expander Board is a secondary board that adds extra functionality, such as additional pumps, lights, or WiFi control.

  • What are the signs of a faulty hot tub PCB?

    If your hot tub PCB is failing, you may notice:

    • Error codes on the control panel.
    • Pump or heater not working despite power.
    • Jets turning on and off randomly.
    • Unresponsive controls or flickering display.
    • Burnt or damaged components on the PCB.
  • What does a hot tub fuse do?

    A fuse protects your hot tub’s electrical system by preventing power surges and short circuits. If a fuse blows, it will cut power to the PCB, pumps, or heater to avoid further damage.

  • How do I know if my hot tub fuse is blown?

    If your hot tub suddenly stops working, check for:

    • No power to the control panel.
    • Pumps, heater, or lights not turning on.
    • A visibly burnt or broken fuse in the control box.
  • What is a hot tub splitter?

    A splitter allows multiple components (e.g., pumps, lights, and WiFi modules) to connect to a single PCB, making it easier to expand your hot tub’s features.

  • What brands of PCBs and expander boards do you stock?

    We stock high-quality PCBs, expander boards, fuses, and splitters from leading manufacturers, including:

    • Balboa – Industry-leading control systems.
    • Gecko – Reliable and high-tech spa controls.
    • Hydroquip & LX – Quality hot tub electronics.
  • How long do hot tub PCBs last?

    A well-maintained PCB can last 5-10 years, but exposure to moisture, power surges, or faulty components can shorten its lifespan.

  • Can I replace my hot tub PCB myself?

    We highly recommend professional installation to prevent electrical damage or voiding warranties. If you’re unsure which PCB or expander board is right for your hot tub, contact our team for expert advice.
