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

When a water heater is not producing hot water, first confirm it has power or gas and that the thermostat is set correctly, then arrange a professional diagnosis if it still runs cold. The most common causes are a tripped breaker, an extinguished pilot or failed igniter, or a failed heating element or thermostat.

• Make sure the electrical breaker is ON or the gas valve is open.
• For gas units, relight the pilot or test the igniter per the manufacturer’s steps.
• Press the reset button on an electric water heater’s upper thermostat if it tripped.
• If the tank is leaking, replacement is typically the right call rather than repair.

If you notice active leaking or smell gas, shut off utilities and contact emergency service immediately. <br/> Updated: 2026-04-02 <br/> Need help in Las Vegas, NV? Call (702) 710-9106 or book online.
