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

If your water heater is not producing hot water, start by confirming power or gas supply, checking the thermostat setting, and pressing the unit’s reset or relighting the pilot if applicable. The most common cause is a tripped breaker on electric models or an extinguished pilot/closed gas valve on gas units. If those checks fail, the issue is often a failed heating element, ignition fault, or a control error that needs a licensed technician. Technicians who work in and around Clifton handle both tank and tankless systems and can advise whether repair or replacement makes the most sense.

Try these quick checks before scheduling service:

• Verify the breaker, switch, or disconnect is on (electric) or that the gas valve is open (gas).
• Confirm temperature is set correctly; wait a full recovery cycle after adjustments.
• Look for leaks or discharge at the relief valve; stop and call if found.
• For tankless, clear inlet screens and note any error codes.

If you smell gas or see active leaking, shut off utilities and water and call a professional immediately. <br/> Updated: 2026-04-04 <br/> Need help in Clifton, VA? Call (571)-650-1016 or book online.
