73524-AA Kohler Whirlpool Pump Replacement System

Replacement for Discontinued Kohler 73524 & 73524-AA Whirlpool Pumps

The Kohler 73524 and 73524-AA whirlpool pumps have been discontinued and are no longer available. These original systems utilized a digital push-button control that connected directly to the bottom of the pump and operated through an electronic circuit board.

Because the pump, digital button, and control board components are no longer manufactured, replacement parts are not available. If any of these components have failed, the recommended solution is to upgrade to this complete replacement system, which is designed to restore your whirlpool tub's operation with modern, readily available components.

Upgrade your Kohler whirlpool with the 73524-AA Kohler Whirlpool Pump Replacement System — a modern, plug‑in solution that brings controlled versatility back to your tub. This isn’t just a swap for the old pump; it’s a complete upgrade that delivers adjustable performance, easier installation, and long‑lasting reliability.

• 1 x 120V, 8.5A Variable Speed Pump — a robust replacement that outperforms traditional single‑speed units and is compatible with ITT MARLOW and other brush motor pumps.
• 1 x 120V Control Box (VSPC) — compact, easy to mount under most tub configurations, designed for clean wiring and simple setup.
• 1 x Wireless Waterproof Floating Remote — control pump speed (Hi, Med, Lo) and power with a 30‑minute timer, all from around the tub.
• 1 x White Push Air Button — convenient interface for configuration or direct manual control; also used to operate the pump and adjust speed.
• Dual control options — keep your existing keypad in place or switch entirely to the remote; the system supports both for flexible operation.
• Included union and minimal installation fuss — free union simplifies plumbing connections; in most cases, no plumbing modifications are required.

Unmatched hydrotherapy control you can feel

The variable speed capability gives you precise hydrotherapy control, letting you tailor intensity for deep relaxation, targeted muscle therapy, or a quick whirl after a long day. The floating remote is waterproof and battery‑powered, so you can adjust settings from anywhere around the tub without stepping into the cabinet area. With two control pathways, you’re not locked to a single interface—use the wireless remote for mobility or push button.

Engineered for a clean, reliable retrofit

Designed with modern components, the 73524‑AA system offers enhanced reliability and a streamlined footprint to simplify retrofits. The compact control electronics can be mounted under the tub, freeing up cabinet space and delivering a tidy installation. The included union supports straightforward connections and reduces the likelihood of leaks during setup. For safe operation, power the pump and control electronics from a dedicated GFCI‑protected circuit.

Installation and setup made straightforward

In most cases, you’ll install without plumbing modifications. Place the new pump on a stable base to minimize vibrations and noise; note that the old pump base may not be compatible with the new unit. The kit is designed for intuitive wiring and mounting, making it feasible for a skilled homeowner or a professional spa technician to complete the job with standard tools.

Who should consider this upgrade

Hot tub owners experiencing a failing or obsolete Kohler 73524‑AA pump will appreciate a modern, reliable replacement that adds adjustable hydrotherapy and flexible controls. It's ideal for installers who replace ITT MARLOW or brush motor pumps and want a feature‑rich, easier install with dual control options. Anyone seeking customizable intensity and the convenience of a waterproof, portable remote will find this system especially valuable.

Practical tips for best results

• Power the system from a dedicated GFCI‑protected circuit to ensure safe operation of both the pump and control electronics.
