State electric water heater: some hot water but runs out quickly.

Safety: Turn off power at the breaker and confirm with a tester.

• Access lower compartment: Remove the lower access panel and insulation.
• Test element: Disconnect wires from the lower element and measure resistance. Replace if open or shorted to ground.
• Check thermostat: Verify the lower thermostat switches power to the element when the tank is partially cooled. Replace if not switching.
