Rheem electric water heater has power but no hot water; continuity test shows open heating element

Safety first: Turn OFF power at the breaker and verify with a non-contact voltage tester. Allow water to cool.

• Test elements: Remove access panels and insulation. Disconnect wires from each element and measure resistance with a multimeter. An open circuit indicates a failed element.
• Drain tank: Close cold inlet, attach a hose to the drain valve, open a hot tap, and drain water below the level of the element.
• Replace element: Use an element wrench to remove the old element. Clean the opening, install a new Rheem-compatible element with a new gasket, and tighten securely.
• Refill and purge: Close drain, open cold inlet, and open hot taps until all air is purged and a solid stream of water flows.
• Restore power: Only after the tank is full, turn the breaker back ON.
