About this circuit board

The VS501 MS1500R1 Series Circuit Board (X801096) is a genuine OEM replacement control board designed for Master Spa hot tubs equipped with MS1500R1 control systems. This Balboa-manufactured circuit board serves as the brain of your spa's electrical system, managing pump operations, heating cycles, and filtration schedules to keep your hot tub running smoothly.

At Bubbles Supply, we guarantee this circuit board will be an exact fit for your Master Spa system. Every VS501 board ships the same day when ordered before our cutoff time and comes backed by our comprehensive 1-year warranty for complete peace of mind. Before installation, ensure your spa is completely powered down and disconnected from electrical supply. If you're unsure about compatibility with your specific Master Spa model, our technical team can verify fitment using your existing board's part number.
