Heater shuts down when it rains or after heavy splashing near the equipment pad.

Safety first: Turn off power before inspecting for water inside the heater.

• Open cabinet: Remove access panels and look for water trails, damp insulation, or pooled water near the Nirvana control board and wiring.
• Seal openings: Check that all conduit entries are sealed with appropriate fittings. Replace missing or damaged gaskets on access panels.
• Protect location: If the heater is exposed to direct rain or splash, consider adding a shelter or deflector that complies with ventilation requirements.
• Dry components: Gently dry any damp electronics and allow time for complete drying before re-energizing. Replace any components that show corrosion or water damage.
