Water Heater Not Working? 5 Common Causes Katy Homeowners Should Know

There is never a convenient time to lose hot water. Whether you are getting ready for work or washing dishes after dinner, a cold surprise from the tap is the last thing anyone wants. The good news is that most water heater problems have clear causes and many can be diagnosed and addressed.

Here are five common reasons your water heater may stop working in the Katy and Houston area:

1. A tripped circuit breaker or blown fuse. Electric water heaters draw significant power. If your breaker trips, the heater will not run. Check your panel first. If it has tripped, reset it once. If it trips again, call us. There may be a deeper electrical issue that needs a professional.

2. A failed heating element. Electric water heaters have two heating elements, upper and lower. If one fails, you may get warm but not hot water, or the water may run out quickly. A plumber can test both elements and replace the faulty one.

3. A faulty thermocouple or gas valve. Gas water heaters rely on a thermocouple to keep the pilot lit. If the thermocouple fails, the pilot goes out and the heater will not ignite. This is a common repair, but it involves working with gas, so it should be handled by a licensed professional.

4. Sediment buildup in the tank. Minerals in the regional water supply fill your tank with scale over time. That scale insulates the bottom of the tank from the heating element or burner, making your heater work harder and recover slower. A professional flush can restore performance, and a water softener can help prevent it from returning.

5. Age. The average tank water heater lasts roughly 10 to 12 years in our area. If yours is older and acting up, replacement is often more cost-effective than repair, especially with today's high-efficiency options that can lower your energy bill.
