How to Fix / Troubleshooting

Safety: Severely corroded components can fail unexpectedly. Do not ignore advanced corrosion.

  • 1. Identify moisture source: Look for slow leaks at joints, valves, or relief discharge. Repair leaks promptly.
  • 2. Check condensate routing: Ensure condensate is not dripping on metal components. Reroute or repair tubing as needed.
  • 3. Environmental factors: Avoid storing pool chemicals, cleaners, or corrosive substances near the heater. Improve ventilation if humidity is high.
  • 4. Replace compromised parts: Have a technician replace heavily corroded fittings, valves, or sections of pipe to prevent failure.
