Hot Tub Circuit Board

The circuit board of your soothing D1 spa is the heart beat and brain of your entire hot tub. It controls everything from simply turning it on, to temperature level, filtration, power and lighting. The circuit board on your spa isn’t much different than the one in your computer, except that it is programmed to deliver specific functions, and do it under what would be considered extreme conditions by any computer.

Remember too, not to panic if your spa is showing a code on the control panel. Not all codes are errors. Sometimes they are system maintenance messages. So be sure that there is a problem first, and then act to correct it. When you do need to replace your Dimension One hot tub’s circuit board, we have what you need and we are ready to help. Easy Spa Parts carries the most complete line of Dimension One Spas pc boards available. Whether your D-1 spa was built last year, or 30 years ago, we carry replacement pc boards in stock. If the D-1 pc board you need is still being manufactured, we have access to it. Have an obsolete hot tub replacement pc board? Give us a call, we can refer you to experienced technicians who repair hot tub pc boards and can keep your Dimension One Spa in good working order

If you need help troubleshooting your hot tub pc board you’ve come to the right place. Some of our technicians worked at Dimension One Spas up to 20 years and can assist you in going from “symptom to solution” right over the phone. This might seem like a daunting task at first but give us a chance because nobody does it better. And whether you install the new spa replacement pc board yourself or have someone else help, we can answer questions as the work is being done to get you back in hot water as soon as possible. Here are just a few things you can keep in mind to watch for to tell if your portable hot tub’s circuit board needs attention:

  • Spa not getting hot or maintaining temperature
  • Pump starting on its own
  • Lighting comes on by itself
  • Error codes appearing
  • Circuit breaker trips
  • Buttons not responding
  • Blinking lights on the panel
  • Wires burnt
  • Connecting straps burnt

  • In some of the cases above, it may be a simple solution and you can give us a call if you think there may be other options besides changing the circuit board.

    Dimension One Spas PC Board

    There are 2 things you can do to promote a longer life for your spa pc board. 1. With the power to the spa off, check each connection where a wire or plug is attached to the pc board. Tighten all loose connections. 2. When you know a lightning storm is coming, turn off power to the spa at the GFI until the storm passes. This prevents a power surge from damaging your Dimension One Spa pc board.

    Keep your portable hot tub clean and inspect all electronics when doing routine maintenance to stay on top of any issues before they become a real problem.

    The @Home Spa Series from Dimension One Spas is a bit unique. If the hot tub pc board needs replacing, the complete 01782-1000 pack must be replaced. Unfortunately, the pc board is not available separately. The benefit of this is having all new electronics in the equipment area as well as a new heater and sensors. Install this and you probably won’t have another electrical issue for 10 more years. We are always ready to help you with any questions you have about the installation and care of your hot tub’s circuit board.

    Hot Tub Circuit Board FAQs

    My upper control panel display is blank. What happened?

    Several things can cause this condition. If you are lucky, the main transformer fuse has blown and needs replacing. The control panel itself may need replacing or the pc board may have problems. Give Easy Spa Parts a call for help troubleshooting the issue.

    Is my spa pc board still available?

    Most are in stock and available to ship the same day. A few are not made anymore. We can suggest a company that repairs older circuit boards to keep your hot tub running.

    Can I replace a circuit board myself?

    Replacing a circuit board can be a little tricky, so we can suggest whether you should get a spa technician or electrician to do the work. On some of the more current units, we made 4-page, 4-color wiring diagrams to make the work easier. The diagrams include large arrows and numbers so wire locations are simpler to find.

    Do all hot tubs have replaceable pc boards?

    In this day of plug and play, some of the newer hot tubs don’t have replaceable circuit boards. Instead you purchase and install the complete lower control pack. Though more costly, the replacement procedure is simpler and makes for fewer installation errors. Call Easy Spa Parts for more information on the design of your hot tub.

    “I feel like you are my personal hot tub repairman. You have probably saved me hundreds of $$$. Sending two parts to try and “just send the one back that doesn’t fix the problem”, and “call me when you get the part, I’ll tell you what to do” is unheard of in today’s world!!! ”
