Fixing a water heater that fails to produce hot water requires diagnosing whether it is electric or gas. For electric models, check the circuit breaker, remove access panels, and press the red high-limit thermal reset button; if elements are burned out, replace them. For gas models, re-light the pilot light or replace a faulty thermocouple that fails to hold the gas valve open. Additionally, flush heavy mineral sediment from the bottom of the tank to restore heating efficiency. Verification: Turn on a hot water tap after repairs to confirm the water reaches normal operating temperatures.
