Water Heater in Greater Jacksonville Area

A water heater not producing hot water is usually caused by lost power or gas, a tripped safety reset, or a failed thermostat or heating element. The most common trigger is a tripped breaker on electric units or an extinguished pilot on gas models after a power or gas interruption. Sediment can also slow or stop recovery on older tanks by insulating the burner or elements. In our day-to-day work around Ponte Vedra’s coastal homes, we also see scald-guard or mixing valves set too low after routine maintenance.

Before calling, try these safe checks:

• Verify the water heater’s breaker/fuse is on; for gas, confirm the gas valve is open and the pilot/igniter lights.
• Set the thermostat to a normal setting and press the unit’s reset button if present.
• Check the status light or error code on the control; note the exact blink pattern or code.
• Test multiple hot taps; if only one fixture is cold, the issue may be a sink mixing valve.

If you smell gas, hear electrical arcing, or find active leaks, shut off power or gas and the cold-water supply and contact a licensed plumber immediately.
