A malfunctioning water heater can disrupt your day-to-day life — no warm showers, no clean dishes. Before you panic, here are some common reasons your water heater might not be working and how a plumbing expert can help.
1. Pilot Light Is Out (Gas Units)
If you have a gas heater and no hot water, the pilot light may have gone out. This can often be relit, but if it won’t stay on, you may have a faulty thermocouple.
2. Tripped Circuit Breaker (Electric Units)
For electric heaters, check your breaker box. A flipped switch might be the reason you’re not getting hot water.
3. Broken Heating Element
Electric water heaters rely on heating elements that can wear out over time and need replacement.
4. Faulty Thermostat
If the temperature isn’t adjusting or remains too low, a malfunctioning thermostat might be the culprit.
5. Sediment Buildup
Over time, minerals from hard water collect in the tank, reducing efficiency and heating capacity.
6. Leaking Tank
If water is pooling around your unit, it could be due to corrosion or a loose connection — both of which require immediate attention.
7. Old Age
Most water heaters last 8–12 years. If yours is near or past that range, it may be time for a replacement.
What a Plumber Will Do:
A licensed plumber can quickly diagnose the issue, recommend repairs or replacement, and ensure safe, efficient operation moving forward.
Final Thoughts:
Don’t ignore the signs of a failing water heater. Prompt inspection and repair can save you from bigger problems and restore comfort fast.
