Frequently Asked Questions
How do I know if the 600-6298 is the right board for my spa?
Check the white sticker near the center of your existing circuit board for the chip number or five-digit Balboa number. If it reads MQ2KUR2A, MQKUR2E2, or 54278, this board is a match. Still unsure? Send us a picture of your board along with your spa's make, model, and serial number.
What's the difference between the 600-6298 and the 600-6292?
They're the same circuit board, built on identical hardware. The only difference is the dip switch configuration: the 600-6298 has switches #3, #5, and #7 up, while the 600-6292 has switches #3 and #8 up.
Do I need any additional parts to install this board?
Most installations are plug-and-play with your existing Molex-style harness. Some setups may also require an expander board (53680) or a compatible 10-button control panel (650-0640), both available separately.
Is this a new or used part?
This is a brand-new circuit board, not a used or refurbished unit.
Will this board work with my control panel?
The 600-6298 is compatible with EL2000, EL2001, and Mach 3 control systems. If you're uncertain whether your topside panel matches, send us your details and we'll verify before shipping.

A Note on International Sourcing
Western Tub and Pool is an international e-retailer, which means we source parts from warehouses across multiple regions. Because shipping origin affects delivery time and cost, we've added region suffixes to our part listings so you know exactly where your item is coming from:
- U = United States
- C = Canada
- E = Europe
- A = Asia
Please note that identical parts may be listed multiple times under different regional suffixes. If you know your part number, check it against these suffixes before ordering. If you're unsure, send us pictures, along with your hot tub's make, model, and serial number, and we'll match you with the right board and the right shipping origin.
