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

If your water heater is not producing hot water, first confirm power or gas is on, then check the unit’s reset/pilot and thermostat before calling a licensed plumber. The most common causes are a tripped breaker (electric), an extinguished pilot or gas supply issue (gas), or a thermostat set too low. Many no‑hot‑water problems are repairable, but a leaking tank usually means replacement is the right call. A burner that lights and then shuts off often points to a dirty sensor rather than a failed valve. Our licensed Denver team services homes in Highlands Ranch every day with same-day and 24/7 help.

Try these quick checks before a service call:

• Electric: reset the breaker and press the water heater’s reset button.
• Gas: relight the pilot per the door label and ensure the gas valve is fully on.
• Verify the thermostat is set to a normal range and not on “vacation.”
• If the tank is leaking from the body, plan for replacement instead of repair. Exactly one helpful sentence: If you smell gas, see active leaking, or the breaker keeps tripping, shut it off and call a pro.
