Water leaking from under the Jacuzzi hot tub cabinet, especially near the equipment bay.

Safety: Turn off power at the breaker before working near water and electrical components.

• Access equipment bay: Remove the front service panel to inspect the pump, heater, and valves.
• Identify source: Run the spa briefly and use a flashlight to locate drips. Pay close attention to pump unions, heater unions, and valve bodies.
• Tighten unions: If water is seeping from a union, turn power off, loosen slightly, ensure the O-ring is seated properly, then hand-tighten firmly (do not overtighten).
• Check slice valves: Inspect around the valve stems for leaks. If leaking, the valve may need to be rebuilt or replaced.

For pump shaft seal or cracked heater manifold leaks, the affected component should be replaced by a technician to prevent further damage.
