Why Choose Our Dimension One® Circuit Boards

Dimension One® Spas has been building premium hot tubs and swim spas out of Carlsbad, California since 1977, earning over 30 patents and CE, UL, GS, and ISO 9001 certifications along the way. Whether you own a Bay Collection spa, a Reflections model, or an @Home budget spa, your circuit board is the brain of the entire system — controlling your heater, pumps, jets, and lighting.

Here's what sets our inventory apart:

  • Extensive model coverage: From 1992 Legend 1500 boards to current Gecko MSPA-MP systems, we carry boards spanning three decades of D1® production.
  • Cross-referenced part numbers: We match your old part number to its current equivalent, including boards that have replaced discontinued versions.
  • Compatible control systems: Boards for Gecko, Balboa, and Spa Builders AFS control systems.
  • Associated repair parts: Control panels, topside panels, spa packs, and M-Drive upper control panels to complete your repair.

Dimensions & Weight

Circuit board dimensions and packaging weights vary by model and control system generation. Because exact specs differ between board revisions, we recommend confirming measurements against your existing board or providing us with your part number, spa make, model, and serial number — we'll verify fit and shipping weight before you order.

 

Frequently Asked Questions

How do I find the right circuit board for my Dimension One® spa?
Locate the part number printed directly on your existing board. If it's damaged or illegible, send us a photo along with your spa's make, model, and serial number, and we'll match it for you.

What's the difference between the Gecko MSPA-MP-D17 and D17-NON LFX boards?
The D17 board supports Liquid FX lighting systems used in Bay Collection spas, while the D17-NON LFX is designed for Reflections Series spas without Liquid FX. Both support M-Drive and are backwards compatible with earlier boards.

My part number is discontinued. What do I do?
Some older boards, like the 01710-80 (D1P, 1997), have been discontinued by the manufacturer. Call us at 1-855-248-0777 or email fixmytub@gmail.com and we'll help source a compatible replacement.

Do you carry related parts, like control panels and spa packs?
Yes. Many circuit boards work alongside topside control panels, spa packs, and M-Drive upper control panels. Let us know your board part number and we'll confirm which associated parts you may also need.

Why do some part numbers have a letter suffix?
As an international e-retailer, we source inventory from multiple regional warehouses. See our shipping note below for details.

 

International Shipping & Part Suffixes

Western Tub and Pool operates as an international e-retailer, which means the same part may be stocked in warehouses across different regions. To keep things clear, we've added regional suffixes to our part numbers:

  • U — United States
  • C — Canada
  • E — Europe
  • A — Asia

Some products may be duplicated across regions under these different suffixes, which can affect shipping times and costs. Always check your part number's suffix, or let us know your location so we can direct you to the closest available stock.

 

Hard-to-Find Part? We'll Track It Down.

Can't locate your exact circuit board or part number? Send us an email at fixmytub@gmail.com with:

  • Your part number (if known)
  • The make, model, and serial number of your hot tub
  • Photos of the board or spa, if available

Our team specializes in sourcing hard-to-find hot tub and spa parts, even for discontinued models. Shop and order at Western Tub and Pool, or call 1-855-248-0777 — we're here to get your spa running again.
