![Relax More. Worry Less. The Automated Spa Monitor.
Stop guessing with messy test kits. The Balboa Purezone™ Hover (Part #96000) floats freely in your spa, automatically monitoring water health so you can focus on relaxing.
[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.

Important Installation Notes
Circuit boards are not plug-and-play. Before installing, please note the following:
Correct component voltage setup is required — component wires on the board may need to be moved
DIP switches must be configured correctly for your system
Some configuration on the topside panel may also be required
Always reference the wiring schematics on the back of the spa pack cover
Do not select a board based on appearance — many boards look nearly identical but contain different software or chips
Electrical or physical damage resulting from improper installation voids the manufacturer's warranty
If you are unsure about any step of the installation process, we strongly recommend engaging a qualified spa technician.
Frequently Asked Questions
How do I know if this is the right circuit board for my hot tub?
The most reliable way to confirm compatibility is to match the Model Number from your spa control system's ID label — typically found on the top of the control box. You can also check the part numbers listed above or contact our team directly.
Can I send in photos to confirm the right part?
Absolutely. Email us at fixmytub@gmail.com with photos of your existing board, your hot tub's make and model, and the serial number. Our team will confirm whether this is the right replacement before you order.
Does this board come pre-configured?
Configuration options may be available depending on where you order. Contact us at 1-855-248-0777 to discuss your specific electrical setup, including your service voltage, pump configurations, and ozonator circuit requirements.
Can I return a circuit board if I order the wrong one?
Circuit boards are non-returnable electrical items, as they cannot be resold once handled. That's why we strongly encourage you to verify your part number or contact us before placing your order.
What warranty does this circuit board come with?
This board is backed by a 1-year limited warranty from Balboa Water Group, covering manufacturer defects. Damage from improper installation or incorrect PCB selection is not covered under warranty.
Does my hot tub need to be serviced by a professional?
If you're comfortable with basic electrical work and spa systems, many owners complete this replacement themselves. However, if you're unsure about voltage configurations or wiring, professional installation is always recommended.

What Is the Balboa 53681 Expander Board?
The Balboa X-P231 Expander Board (part number 53681) is a factory-original daughter board designed to extend the pump output capacity of compatible Balboa VS and EL-series spa control systems. This is not a standalone main board — it mounts inside your spa pack alongside your existing main board to add a dedicated 1-speed pump output with its own on-board 30-amp fuse.
The 53681 is a direct upgraded replacement for the discontinued 53290 expander board, featuring a higher 30-amp fuse rating that supports full-sized jet pumps — something the older 10-amp design simply could not handle.

Why Choose the Balboa 53681 Expander Board?
Factory-Original OEM Quality
Manufactured by Balboa Water Group — the original maker of VS and EL control systems. Not a third-party clone.
Upgraded From the 53290
The discontinued 53290 carried only a 10-amp fuse and was limited to blower or circulation pump duty. The 53681 steps up to a 30-amp fuse, meaning it can handle a full-sized 1-speed jet pump without overloading your system.
Easy Plug-and-Connect Installation
The RJ45 phone-style connector makes attachment to the main board fast and secure. Ships as a complete kit with all necessary cables included.
1-Year Factory Warranty
Covered under Balboa Water Group's manufacturer's limited warranty, giving you peace of mind long after installation.
Wide OEM Brand Coverage
Used as original equipment in spas from Clearwater, Cal Spas, Beachcomber, Thermo Spas, and Vita Spas — one of the most widely used expander boards in the industry.
Frequently Asked Questions
Is the 53681 a complete main control board?
No. The 53681 is an expander (daughter) board only. It must be installed alongside a compatible VS513Z, VS515Z, VS514SZ, or EL2001 main board — it does not replace the main board.
How do I know if my hot tub needs this expander board?
Check the part number on your existing expander board. If it shows 53290 or X-P231, the 53681 is your replacement. You can also call us at 1-855-248-0777 or send us a photo of your board to fixmytub@gmail.com and we'll confirm the correct part for you.
What is the difference between the 53681 and the older 53290?
The 53290 is discontinued. It had a 10-amp fuse and was only rated for a blower or circulation pump. The 53681 replaces it with a 30-amp fuse, allowing it to drive a full-sized 1-speed jet pump. The connectors and mounting are the same, so it is a direct drop-in replacement.
Will I need to configure DIP switches after installation?
Most likely yes. DIP switch settings on the main board control how the expander circuit behaves. Refer to the wiring schematic for your specific main board. Contact us if you need guidance — our team is happy to help.
Does this board work with VS520-series systems?
No. The 53681 X-P231 is specified for VS513Z, VS515Z, VS514SZ, and EL2001 systems. For VS520-series systems, a different expander board is typically required. Call us and we'll point you in the right direction.
Can I return the board if it doesn't fit my system?
Circuit boards are non-returnable per manufacturer policy. Please verify compatibility before ordering. We strongly encourage you to check your part number or contact us first — that's what we're here for.
Does installation require a licensed electrician?
Yes. NEC and most local codes require a licensed electrician for all hot tub electrical work. Incorrect installation can damage the board and will void the manufacturer's warranty.

Finding the right hot tub part can be tricky — especially when part numbers vary by OEM brand or firmware revision. At Western Tub and Pool, we specialize in hard-to-find hot tub replacement parts and have the expertise to help you identify exactly what you need.

Why Choose the Balboa 53681 Expander Board?
Factory-Original OEM Quality
Manufactured by Balboa Water Group — the original maker of VS and EL control systems. Not a third-party clone.
Upgraded From the 53290
The discontinued 53290 carried only a 10-amp fuse and was limited to blower or circulation pump duty. The 53681 steps up to a 30-amp fuse, meaning it can handle a full-sized 1-speed jet pump without overloading your system.
Easy Plug-and-Connect Installation
The RJ45 phone-style connector makes attachment to the main board fast and secure. Ships as a complete kit with all necessary cables included.
1-Year Factory Warranty
Covered under Balboa Water Group's manufacturer's limited warranty, giving you peace of mind long after installation.
Wide OEM Brand Coverage
Used as original equipment in spas from Clearwater, Cal Spas, Beachcomber, Thermo Spas, and Vita Spas — one of the most widely used expander boards in the industry.
Frequently Asked Questions
Is the 53681 a complete main control board?
No. The 53681 is an expander (daughter) board only. It must be installed alongside a compatible VS513Z, VS515Z, VS514SZ, or EL2001 main board — it does not replace the main board.
How do I know if my hot tub needs this expander board?
Check the part number on your existing expander board. If it shows 53290 or X-P231, the 53681 is your replacement. You can also call us at 1-855-248-0777 or send us a photo of your board to fixmytub@gmail.com and we'll confirm the correct part for you.
What is the difference between the 53681 and the older 53290?
The 53290 is discontinued. It had a 10-amp fuse and was only rated for a blower or circulation pump. The 53681 replaces it with a 30-amp fuse, allowing it to drive a full-sized 1-speed jet pump. The connectors and mounting are the same, so it is a direct drop-in replacement.
Will I need to configure DIP switches after installation?
Most likely yes. DIP switch settings on the main board control how the expander circuit behaves. Refer to the wiring schematic for your specific main board. Contact us if you need guidance — our team is happy to help.
Does this board work with VS520-series systems?
No. The 53681 X-P231 is specified for VS513Z, VS515Z, VS514SZ, and EL2001 systems. For VS520-series systems, a different expander board is typically required. Call us and we'll point you in the right direction.
Can I return the board if it doesn't fit my system?
Circuit boards are non-returnable per manufacturer policy. Please verify compatibility before ordering. We strongly encourage you to check your part number or contact us first — that's what we're here for.
Does installation require a licensed electrician?
Yes. NEC and most local codes require a licensed electrician for all hot tub electrical work. Incorrect installation can damage the board and will void the manufacturer's warranty.
