Common Questions
How do I know if this is the right board for my spa?
Check the white chip sticker near the center of your existing circuit board. If it reads LZM1UR1, LZM2UR1A, LZM2UR1B, or LZM2UR1C, this board is a match. Your spa's model and year should also fall within our compatibility list above.
What if I can't find the chip number on my old board?
No problem—send us clear photos of your existing board along with your spa's make, model, and serial number, and our team will confirm the correct part for you.
Does this board work with any topside control panel?
This board is confirmed compatible with the 650-0635 topside panel. If your spa uses a different topside, contact us before ordering to confirm fit.
Is this board new or refurbished?
This is a brand-new, factory-original board that has never been installed.
Can I return this part if it doesn't fit?
Circuit boards are non-returnable once purchased, so please confirm your chip number, spa model, and year with our team before placing your order.
Do I need an electrician to install this?
Yes. Installation should be performed by a licensed electrician in compliance with NEC Article 680 and all applicable local codes, including proper GFCI protection and grounding.

As an international e-retailer, Western Tub and Pool sources parts from warehouses across multiple regions, which can affect shipping times. To help you identify where your part ships from, we've added regional suffixes to our part numbers: U for U.S.A., C for Canada, E for Europe, and A for Asia. Because of this, you may see what looks like a duplicate listing for the same part—this simply reflects a different regional warehouse.
If you already know your part number, double-check it against the listing before ordering. If you're not sure, send us pictures of the part along with your hot tub's make, model, and serial number, and we'll help you find the exact match.](https://cdn11.bigcommerce.com/s-b7yzllubsu/images/stencil/500x659/products/4575/6853/600-6293__28394.1789504002.PNG?c=2 "Marquis LZM2UR1B Circuit Board 600-6293 – Genuine Replacement Spa Pack Board
Restore your Marquis spa to full working order with the 600-6293 circuit board, the OEM Balboa-manufactured replacement for 2006-2008 Marquis models. If your control panel isn't responding, your pumps won't kick in, or your spa is throwing error codes, a failing circuit board is often the culprit—and this board is the exact fix your system needs.
[Shop and Order at Western Tub and Pool]
Why This Board Is the Right Fix
Genuine OEM Quality: Manufactured by Balboa for Marquis spa systems, this is a brand-new, factory-original board—not a generic aftermarket substitute.
No Pressure Switch Needed: Built on the VS501Z platform with Balboa's M7 technology, this board handles temperature and water flow sensing without a separate pressure switch, meaning fewer parts to fail down the line.
Full-Function Control: Runs your 2-speed primary pump, 1-speed secondary pump, 12V spa light, and ozonator, so every feature of your spa stays operational.
Confirmed Compatibility: Covers a wide range of 2006 and 2007 Marquis models, plus every 2008 Marquis spa, so there's a strong chance this is the exact board your tub needs.
Direct Upgrade Path: This board replaces the older 600-6288, so if your spa used that part, 600-6293 is your drop-in solution.
