Why This Circuit Board Matters

When your spa's circuit board fails, everything stops — heating, jets, controls. Replacing it with the exact correct board gets your hot tub back up and running fast. The Balboa VS520DZ Circuit Board is the brain of the VS520DZ control system, and getting the right one matters more than most people realize.

This is a hard-to-find, discontinued part. Western Tub and Pool has new units in stock. Once they're gone, they're gone. Don't wait.

Product Specifications

What Is the VS520DZ Circuit Board Used In?

The Balboa VS520DZ Circuit Board (chip number VS520DZR1B) is designed specifically for VS520DZ control boxes and control packs. It is part of Balboa's Value Series (VS) family, which was used across a wide range of hot tub and spa brands.

Compatible spa control systems and brands that commonly used VS520DZ Balboa control packs include:

• Great Lakes Spas — GVS500, GVS500SZ, GVS501, GVS510, GVS511, and GVS511SZ series
• Leisure Bay Spas — VS120R and VS240R series
• Master Spas — VS 501 and VS 510 Pack series
• Hydro Spa — HS200VS series
• Cal Spa — Models using VS300FC control packs
• Keys Backyard Spas — Various models using VS series Balboa control systems
• Nordic Spas — Models using NORVS300 control systems
• Many private-label spa brands that used Balboa VS520DZ factory control packs

Important: Do not order a circuit board based on looks alone. Several Balboa boards appear identical but contain different chips and software. Always verify using the chip number found on a small white sticker near the center of your board. The chip number for this board is VS520DZR1B. If you are unsure, contact Western Tub and Pool before ordering.

Not Sure If This Is the Right Board for You?

Here's how to confirm your part:

1. Check Your Chip Number

Locate the white sticker on the front or back of your existing circuit board. The chip number — in this case VS520DZR1B — is printed there.

2. Find Your Part Number

Look for a five-digit number on the board itself. For this board, that number is 55152.

3. Know Your Hot Tub's Make, Model, and Serial Number

These details help our team confirm you're ordering the right part the first time.

4. Still Not Sure? Send Us a Photo

Email a clear photo of your existing circuit board — along with your spa's make, model, and serial number — to fixmytub@gmail.com and our team will help you identify the correct replacement.
