No hot water, but EcoSmart display is on and shows normal readings; temperature set correctly.

Safety: Turn OFF power at the breaker before testing elements or wiring.

• Check for error messages: Confirm there are no hidden error codes or flashing indicators on the display.
• Verify supply voltage: With a multimeter (if qualified), confirm correct voltage at the heater input terminals.
• Test elements: Disconnect each heating element and measure resistance across its terminals. An open circuit indicates a failed element that must be replaced.
• Inspect element wiring: Ensure all element terminals are tight and free of corrosion or burn marks.
• Control board check: If elements test good but never receive power when hot water is demanded, the control board’s switching devices may be faulty and require replacement.
