What Should I Do If My Water Heater Is Not Producing Hot Water?

If a water heater stops producing hot water, check the power or gas supply and verify the thermostat setting before calling for service. The most common causes are a tripped breaker, an extinguished pilot/igniter issue, or a failed thermostat or heating element. If a reset works but trips again, a thermostat or element is likely failing and needs diagnosis. Our plumbers handle all major brands and fuel types, and we work in the Greenwood area every day. Repairs are backed by our guarantees.

Try these quick checks before scheduling service:

  • Electric: confirm the breaker is on; press the red high‑limit reset after turning power off.
  • Gas: ensure the gas valve is on; relight the pilot/igniter per the unit’s label; stop if it won’t stay lit.
  • Make sure the control isn’t in vacation mode; set to about 120°F and allow 30–60 minutes to recover.
  • If the tank is 10+ years old or leaking from the shell, plan replacement instead of repair. Always turn off power or gas and the cold‑water supply if you see active leaks or scorching.
