When a Waco home has no hot water, the fastest path is to separate a simple reset from a repair that needs safety testing.
Start by checking whether the issue affects every fixture or only one shower or sink. A whole-home problem usually points to the water heater, while one fixture may be a mixing valve, cartridge, or fixture issue.
A tank leak at the base needs faster triage than rusty water or a weak pilot. Shut off water to the unit if water is spreading, keep the area clear, and avoid opening panels or gas controls if you smell gas or see scorch marks.
Electric water heaters can lose hot water after a tripped breaker, failed element, or thermostat problem. Gas units can fail from pilot, igniter, gas-control, venting, or flame-sensor issues.
