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

If a water heater is not producing hot water, first confirm it has power or gas and that the temperature is set correctly, then schedule service if the issue persists. The most common causes are a tripped breaker on electric units or an extinguished pilot/ignition fault on gas models. Treat active leaks or gas odors as urgent, but most no‑hot‑water calls are routine once a tech checks fuel, ignition, and controls. Our team can diagnose whether a repair or a replacement makes better sense after an inspection, and we routinely service major tank and tankless brands. We also assist homeowners throughout the Saint John area with 24/7 emergency help when needed.

Try these quick checks before you call:

• Check the breaker or power switch; on electric units, press the red high‑limit reset if it tripped.
• Verify gas supply is on and relight the pilot or note any ignition error code.
• Raise the thermostat to at least 120°F and wait 20–30 minutes after heavy use.
• If you see pooling water or smell gas, shut off utilities to the unit.
