[Shop the Purezone Hover at Western Tub and Pool ]
Smart water care made simple
Maintaining your hot tub shouldn't feel like a chemistry experiment. The Balboa Purezone Water Monitoring System with Hover replaces manual testing with advanced optical technology, delivering precision and peace of mind.
Forget messy test kits
Say goodbye to color-matching strips and liquid reagents. Purezone automates the process, checking your water daily or every other day without you lifting a finger.
Precision optical readings
Using advanced optical sensors, Purezone measures key water parameters including pH, free chlorine, total alkalinity, and temperature. This ensures your water is safe, clean, and comfortable for every soak.
Real-time alerts & expert advice
Connected via the Purezone app (iOS and Android), the system sends alerts directly to your phone. It doesn’t just tell you the levels; it provides personalized chemical dosing recommendations tailored to your specific spa size and sanitizer type.
Floats freely with no installation
Unlike wall-mounted monitors that require drilling, the Purezone Hover (96000) simply floats in your water. It’s the perfect "drop-and-go" solution for existing hot tubs.
How it works
1. Connect the App
Download the Purezone app, create your profile, and input your spa details (size and sanitizer type) for customized advice.
2. Float and Monitor
Place the charged Purezone Hover unit into your spa water. It uses a replaceable P3 cassette to perform automated tests.
3. Get Results
Receive instant updates on your phone. If your water needs attention, the app tells you exactly what to add to balance it.
Is my hot tub compatible?
The Balboa Purezone Hover is a floating system designed to work with most residential spas and swim spas up to 2,400 gallons (9,084 Liters).
Because it floats independently and operates on a rechargeable battery, it does not require a specific Balboa control pack to function as a monitor. It is an excellent addition for owners of major spa brands, including:
Cal Spas
Marquis Spas
Master Spas
Artesian Spas
Jacuzzi
Sundance
dynasty spa
maax spa
...and many others.
Note: If you are looking for the wall-mounted version, please check for the "Dock" model (Part #97000). The Hover (Part #96000) is designed specifically for floating use.
Not sure if this is the right part?
Check your current equipment part number or consult our online catalog.

Frequently Asked Questions
How do I know if this is the right circuit board for my spa?
Look at your existing circuit board for the chip number printed on it. If it reads CS6100R1A (or any variant ending in a different letter), this is your board. You can also check your control box for the label 53988-01 — this board is the direct replacement. If you're still unsure, email a photo of your current board along with your spa's model and serial number to fixmytub@gmail.com.
What does this circuit board control?
The ELE09100222 manages all core spa functions, including water heating, pump operation, jet timing, filtration cycles, ozone generation, and spa lighting. It is the central control unit of your spa system.
Can I install this board myself?
Many experienced spa owners install this board themselves. The board uses a plug-and-play design that mirrors the original wiring harness. That said, always disconnect power at the main breaker before beginning, wear insulated gloves, and allow at least 5 minutes for capacitors to discharge. If you're not confident working with electrical components, we recommend hiring a licensed spa technician.
What should I do if I'm getting error codes after installation?
Common post-installation codes include "SnS" (sensor mismatch) and "HL" (high-limit fault). Double-check that all sensor wires are connected correctly — red to J1 positive, black to ground. If errors persist, power off the spa and re-inspect all wiring connections before contacting us for support.
What is the expected lifespan of this board?
Under normal residential use, the ELE09100222 has an expected lifespan of 8 to 10 years. With proper maintenance — including annual connector inspections and keeping the control box dry — it can last up to 15 years. In high-usage or commercial settings, expect closer to 5 to 7 years.
Do you ship across the United States?
Yes. Western Tub and Pool ships throughout the US. Contact us for shipping timelines and availability, as stock on this part can be limited.
What information should I have ready when I call or email?
To help us find the right part quickly, please have the following on hand:
Your spa's make and model
Serial number (usually on a sticker inside the equipment bay)
Chip ID number from your existing circuit board
A photo of your current board if available

If you're still unsure, email a photo of your current board along with your spa's model and serial number to fixmytub@gmail.com.
What does this circuit board control?
The ELE09100222 manages all core spa functions, including water heating, pump operation, jet timing, filtration cycles, ozone generation, and spa lighting. It is the central control unit of your spa system.
Can I install this board myself?
Many experienced spa owners install this board themselves. The board uses a plug-and-play design that mirrors the original wiring harness. That said, always disconnect power at the main breaker before beginning, wear insulated gloves, and allow at least 5 minutes for capacitors to discharge. If you're not confident working with electrical components, we recommend hiring a licensed spa technician.
What should I do if I'm getting error codes after installation?
Common post-installation codes include \"SnS\" (sensor mismatch) and \"HL\" (high-limit fault). Double-check that all sensor wires are connected correctly — red to J1 positive, black to ground. If errors persist, power off the spa and re-inspect all wiring connections before contacting us for support.
What is the expected lifespan of this board?
Under normal residential use, the ELE09100222 has an expected lifespan of 8 to 10 years. With proper maintenance — including annual connector inspections and keeping the control box dry — it can last up to 15 years. In high-usage or commercial settings, expect closer to 5 to 7 years.
Do you ship across the United States?
Yes. Western Tub and Pool ships throughout the US. Contact us for shipping timelines and availability, as stock on this part can be limited.
What information should I have ready when I call or email?

Frequently Asked Questions
What does the Balboa VS520SZ circuit board do?
The VS520SZ PCB is the brain of your hot tub's control system. It manages all major electrical components — jet pumps, heaters, lights, blowers, ozone systems, and more. When this board fails, your spa may stop heating, lose pump function, or shut down entirely.
Is this a genuine Balboa circuit board?
Yes. The 33-55299-K sold by Western Tub and Pool is a brand new, genuine Balboa Water Group circuit board, not an aftermarket imitation.
How do I know if my circuit board has failed?
Common symptoms of a failed Balboa VS520SZ circuit board include:
Spa will not power on or keeps tripping the breaker
Error codes on your topside display (e.g., FLO, OH, DR, HOT)
Pumps or heater not responding to controls
Intermittent or complete loss of control panel function
Burnt smell or visible damage on the board
Can I install this circuit board myself?
Circuit board replacement requires knowledge of spa electrical systems. Improper installation or incorrect PCB selection voids the manufacturer's warranty and may damage other components. If you are not experienced with spa electrical work, we recommend hiring a qualified spa technician.
Does the board come pre-configured?
Configuration requirements (DIP switch settings, jumper positions, and voltage settings) vary by installation. Contact us before ordering and we can advise on pre-configuration options. Our team at Western Tub and Pool is happy to walk you through what you need.
What is the warranty on this circuit board?
This board comes with a manufacturer's limited warranty. Contact us at 1-855-248-0777 or fixmytub@gmail.com for full warranty terms and conditions.
Do you ship across Canada and the United States?
Yes. Western Tub and Pool ships spa parts across North America. Contact us for shipping options and delivery timelines to your location.

Frequently Asked Questions
What does the Balboa VS520SZ circuit board do?
The VS520SZ PCB is the brain of your hot tub's control system. It manages all major electrical components — jet pumps, heaters, lights, blowers, ozone systems, and more. When this board fails, your spa may stop heating, lose pump function, or shut down entirely.
Is this a genuine Balboa circuit board?
Yes. The 33-55299-K sold by Western Tub and Pool is a brand new, genuine Balboa Water Group circuit board, not an aftermarket imitation.
How do I know if my circuit board has failed?
Common symptoms of a failed Balboa VS520SZ circuit board include:
Spa will not power on or keeps tripping the breaker
Error codes on your topside display (e.g., FLO, OH, DR, HOT)
Pumps or heater not responding to controls
Intermittent or complete loss of control panel function
Burnt smell or visible damage on the board
Can I install this circuit board myself?
Circuit board replacement requires knowledge of spa electrical systems. Improper installation or incorrect PCB selection voids the manufacturer's warranty and may damage other components. If you are not experienced with spa electrical work, we recommend hiring a qualified spa technician.
Does the board come pre-configured?
Configuration requirements (DIP switch settings, jumper positions, and voltage settings) vary by installation. Contact us before ordering and we can advise on pre-configuration options. Our team at Western Tub and Pool is happy to walk you through what you need.
What is the warranty on this circuit board?
This board comes with a manufacturer's limited warranty. Contact us at 1-855-248-0777 or fixmytub@gmail.com for full warranty terms and conditions.
Do you ship across Canada and the United States?
Yes. Western Tub and Pool ships spa parts across North America. Contact us for shipping options and delivery timelines to your location.
What if I can't find my part number?
No problem. Send us an email at fixmytub@gmail.com with photos of your existing board and your hot tub's make, model, and serial number. We'll identify the right part for you.
