Safety: Turn off power at the breaker and confirm with a meter before servicing.

• 1. Access lower components: Remove the lower access panel and insulation.
• 2. Test lower element: Disconnect wires and measure resistance across the lower element terminals. Replace if open or shorted to ground.
• 3. Check lower thermostat: Test for continuity when calling for heat. Replace if it does not close properly.
• 4. Inspect for sediment: Drain a few gallons from the tank and observe for heavy sediment. If present, fully drain and flush the tank to prevent future element failure.
