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

If a water heater is not producing hot water, start with simple checks and then schedule professional diagnosis if heat does not return. The most common cause is a power, gas, or control issue that interrupts heating, followed by scale buildup that blocks sensors or elements. In Central Texas, hard water can quickly foul tank and tankless systems, so descaling or flushing is often part of the fix. Our team services both tank and tankless units, and same-day repairs are often possible when parts are on the truck.

Try these quick checks before you call:

• Electric: verify the breaker isn’t tripped; on tanks, a tripped high‑limit reset suggests an underlying fault.
• Gas: confirm the gas valve is on and the pilot/igniter lights safely per the manufacturer label.
• Thermostat/mode: make sure temperature isn’t set too low or on “vacation.”
• Tankless: look for error codes or a dirty inlet screen and note the code for your technician.

If you smell gas, hear sizzling at the panel, or see active leaking, shut it down and call for service immediately. <br/> Updated: 2026-04-04 <br/> Need help in Manor, TX? Call (512) 309-0360 or book online.
