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

A water heater that produces no hot water usually points to lost power or gas, a tripped safety limit, or a failed heating component. The most common root is the control or ignition system preventing the burner or elements from heating. On electric tanks, when the upper element fails, you get no hot water at all; a lower-element failure gives brief warm water then cold. Our licensed plumbers service Arlington homes daily and can confirm whether repair or replacement makes the most sense for age and condition.

Try these quick checks before calling:

• Electric: reset the breaker and press the water heater’s high‑limit reset; then allow 30–60 minutes for recovery.
• Gas: ensure the gas valve is on and relight the pilot or check electronic ignition per the manual.
• Set the thermostat to about 120°F and verify the power switch is on; restore any shutoff you find closed.
• If you see an active leak, smell gas, or notice soot/burn marks, shut off water and power/gas and call a professional.

If these checks don’t restore hot water, book a diagnostic so a licensed plumber can safely test elements, valves, and sensors. <br/> Updated: 2026-04-02 <br/> Need help in Arlington, TX? Call (214) 945-0660 or book online. "Steve did a great job installing a new water heater." — Michelle M.
