Jacuzzi pool heater shuts down during heavy rain or after exposure to sprinklers.

Safety first: Turn off power and gas. Do not operate the heater while wet inside.

Steps to dry and protect:

• Open cabinet: Remove access panels and allow the interior to dry completely. Use a dry cloth to wipe visible moisture.
• Inspect gaskets and covers: Replace missing or damaged panel gaskets that allow water entry.
• Check connectors: Clean and dry corroded connectors; apply dielectric grease where appropriate.
• Improve site drainage: Ensure the heater pad is above grade and that sprinklers do not spray directly on the unit.
