Why Your Water Heater Isn’t Working (And What You Can Do About It)

Hot water gone cold? You’re not alone. In Northern New Jersey — where winters hit hard — a broken water heater can disrupt your whole day. Whether your water heater stopped working overnight or your new hot water system isn’t heating properly, figuring out the cause can be frustrating.

Let’s walk through the most common reasons your water heater is not working — and what you can do before calling a pro.

1. No Power or Gas? Why Your Water Heater Might Not Be Working

One of the most overlooked issues is simple: your water heater may have lost power or stopped receiving gas.

• For electric models, check your circuit breaker. A tripped breaker is an easy fix.
• For gas models, see if the pilot light is out or if there’s an issue with the gas supply.

🔧 If you just installed a new water heater, it’s worth double-checking that it was connected properly. If you’re not sure, consider scheduling a professional water heater repair in Clifton.

2. Thermostat Issues: Why the Water Heater Doesn’t Heat Properly

Sometimes the heater works — just not well. If the water is lukewarm or keeps running out fast, your thermostat could be misconfigured or faulty.

• Make sure the temp is set around 120°F (49°C) — not lower.
• If it’s a dual-element heater, one of the elements may have failed.

🧊 Bonus tip: In winter, cold inlet water is colder than usual, so recovery times are longer. If your home heating system is also acting up, a heating repair service in Clifton might be needed alongside the water heater fix.

3. Sediment Buildup: A Common Reason Hot Water Heater Stops Working

If you hear popping or rumbling, or if your hot water tank stopped working gradually, sediment might be the problem.

Over time, minerals in hard water settle at the bottom of the tank, reducing heating efficiency and damaging the unit.

Symptoms of buildup:

• Less hot water than usual
• Odd noises
• Longer heating times

Flushing the tank yearly can help — but if it’s been ignored for too long, the heater may quit working entirely. In some cases, upgrading your system may be the smarter move. Learn more about furnace installation in Clifton if you’re planning a full upgrade.

4. Broken Heating Elements or Burner: Water Heater Malfunctions Explained

In electric water heaters, burned-out elements are a common failure point. For gas units, it might be a bad burner or thermocouple.

These issues usually require professional diagnosis, especially if:

• The water never heats up at all
• You hear clicking but nothing ignites
• The unit cycles on/off without actually heating

If you’re also noticing furnace issues during colder months, it might be worth checking in for furnace repair in Clifton to rule out broader system failures.

5. Old Unit? Why a Water Heater Stops Working After 10+ Years

Water heaters aren’t built to last forever. The average lifespan is around 8 to 12 years.

If your home water heater isn’t working and it’s pushing a decade or more, repair might not be worth it.

Look out for:

• Rust-colored water
• Leaks around the base
• Weird smells or noise
• Frequent resets or fuse blows

If you’re using a boiler system, these may also be signs that you need boiler repair or even a complete boiler installation in Clifton.
