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

If your water heater isn’t producing hot water, start with quick safety checks and basic resets before calling a pro. The most common causes are a tripped breaker or high‑limit switch on electric units, an extinguished pilot or ignition failure on gas units, or a thermostat set too low or in vacation mode; sediment buildup or a failed element/thermocouple are also frequent.

We regularly service units in the Leo-Cedarville area, where mineral-heavy water can scale parts and cut output, especially on tankless systems.

Try these simple steps:

• Electric: check the breaker and press the water heater’s high‑limit reset.
• Gas: confirm the gas valve is on and relight per the manufacturer’s instructions.
• Verify the thermostat (about 120°F) and that vacation mode is off.
• Call a pro if you see rusty water, loud popping, repeated pilot outages, or a tank older than ~15 years.

If you smell gas, see active leaking, or the breaker keeps tripping, shut the unit down and call a licensed plumber immediately. <br/> Updated: 2026-04-02 <br/> Need help in Leo-Cedarville, IN? Call (260) 222-8183 or book online.
