Safety First: Quick Rules Before You Troubleshoot

Loss of hot water often has simple causes, but water heaters store energy in hot water, gas, or electricity. Stay safe while you check.

• Turn power off at the breaker for electric units before removing any panels.
• Set gas control to Vacation or Off if you smell gas. Ventilate and call a pro.
• Avoid opening the tank or pulling parts under pressure. The temperature and pressure relief valve protects the tank from excess pressure.
• Recommended temperature is about 120°F for most homes. This helps reduce scalding risk and saves energy.

If you are unsure at any point, stop and schedule service. A fast professional visit often costs less than a damaged component.

1) Thermostat or Temperature Setting Issues

A mis‑set or failed thermostat is one of the most common reasons for no hot water or water that runs warm, then cold.

What to check now:

1. Confirm the temperature setting. Most homes do well at 120°F. If someone turned it down, your showers will feel lukewarm.
2. For electric units, many models have upper and lower thermostats behind panels. A failed upper thermostat or high‑limit switch can cut all heat.
3. For gas units, confirm the dial is set to Hot or a numerical setting. If it is set to Pilot or Vacation, you will not have full heat.

DIY steps:

• Reset the high‑limit button on electric models. Turn off power at the breaker first, remove the upper panel, and press the red reset if tripped. Restore power and test.
• Return the dial to 120°F. Wait several hours for full recovery in a standard 40–50 gallon tank.

When to call Summers:

• If the high‑limit trips again.
• If thermostats need replacement or calibration. We carry OEM parts and can test sensors quickly on site.

2) Power Supply or Breaker Problems

Electric heaters rely on a dedicated 240‑volt circuit. Any break in that path leads to cold water.

Signs and checks:

1. Tripped breaker or blown fuse. Open your panel and look for a tripped two‑pole breaker.
2. Loose wiring at the disconnect or heater junction box. Heat cycles can loosen screws over time.
3. GFCI trips on certain installs. Some code updates require protection in specific locations.

DIY steps:

• Reset the breaker once. If it trips again, do not keep resetting.
• Inspect for scorch marks on access panels. If present, call a pro immediately.

Why this happens:

• Shorted heating element drawing excessive current.
• Aging breakers that no longer hold under normal load.
• Moisture intrusion in the junction box.

Summers can test amperage draw, isolate the fault, and replace failed elements or wiring to restore safe operation the same day.

3) Pilot Light, Thermocouple, or Ignition Failure (Gas)

Gas water heaters depend on ignition to heat the burner. If the pilot is out or the igniter fails, you will not get hot water.

Symptoms:

• No flame in the viewing window.
• Clicking without ignition on electronic models.
• Pilot lights but goes out when you release the button.

DIY steps for standing‑pilot models:

1. Follow the lighting instructions on your water heater label. Hold the pilot button and ignite. Continue holding for the recommended time before releasing.
2. If the pilot will not stay lit, the thermocouple may be weak. It senses flame and allows gas to flow.

For electronic ignition:

• Replace batteries if your model uses them. Listen for the spark. If you hear repeated clicks with no flame, the igniter or gas flow may be the issue.

Call Summers when:

• You smell gas at any time.
• The pilot will not stay lit after following the manufacturer’s steps.
• You need a new thermocouple, flame sensor, or gas control valve. We stock common parts and provide clear, written estimates before work.

4) Sediment Build‑Up Reducing Heat Transfer

Fort Wayne and surrounding areas often have mineral‑rich water. Over time, sediment settles in the bottom of a tank water heater and insulates the water from the burner or elements. That slows recovery and can leave you with short showers or no hot water.

What to look for:

• Popping or rumbling sounds during heating.
• Cloudy water that clears after a few seconds.
• Hot water that turns cold quickly.

DIY maintenance:

1. Turn off power or set the gas to Pilot.
2. Connect a hose to the drain valve and run it to a safe drain.
3. Open the drain and a nearby hot water faucet to let air in. Flush until clear.

Why flush:

• Restores efficient heat transfer.
• Helps protect the tank and extends service life.

If the drain valve is clogged or will not open, do not force it. Our techs can safely flush, replace a stubborn valve, and check the anode rod. Many manufacturers recommend annual flushing in areas with hard water.

5) Failed Heating Elements or Gas Control Valve

If power and thermostats check out on electric units but you still have no hot water, a burned‑out element is likely. On gas units, the gas control valve or burner assembly may fail.

Electric elements:

• Upper element failure often equals no hot water at all.
• Lower element failure causes short hot water and quick temperature drop.

Gas controls:

• A faulty gas valve can block fuel to the burner.
• A failed flame sensor prevents ignition.

Diagnosis and fix:

• We meter resistance, check continuity, and test live amperage to confirm element or control failure.
• Typical element replacements are completed in one visit. Gas valve replacement requires leak checks and manufacturer procedure.

When repair is not the best choice:

• If your tank is 10–12 years old, repeated repairs may cost more than a new, efficient unit. We install both tank and tankless systems and size them to your family’s usage.

Bonus: Why Water Is Too Hot or Fluctuates

Sometimes the issue is not heat loss but spiking temperatures. That can be just as risky.

Common causes:

• Thermostat set above 120°F. Kids and seniors are more sensitive to scalding.
• Stuck mixing valve or crossover between hot and cold lines.
• Air in lines causing groaning noises and irregular flow. Draining and restarting the tank, then releasing air through a sink, often resolves this.

Summers can balance your system, replace a sticking valve, and show you the recommended setting for steady, safe hot water.

Repair vs Replace: How to Decide

Every situation is unique. Use these simple rules to protect your budget.

Choose repair if:

1. The unit is under 8 years old and well maintained.
2. The tank is sound with no rust or leaks.
3. The fix is a control, thermostat, or single element.

Consider replacement if:

1. Age is 10–12 years or more for a standard tank.
2. There is visible rust, leaks, or the T&P valve drips constantly after testing.
3. You need more capacity or faster recovery for growing family needs.

Benefits of a modern install:

• Improved performance and durability.
• Better energy efficiency and lower utility costs.
• Fewer repairs and more environmentally friendly options, including tankless.

Preventive Maintenance That Works in Fort Wayne

Local water conditions and seasonal swings matter. A simple routine can help you avoid future downtime.

• Annual flush and safety inspection. We drain sediment, test the relief valve, and check combustion or elements.
• Anode rod check every 3–5 years. Replacing it can extend tank life.
• Verify expansion tank pressure where installed. Match house water pressure for best results.
• Set temperature at 120°F and label the dial to prevent accidental changes.
• Test hot water at the farthest fixture to confirm stable delivery.

We provide on‑site evaluations and complete written estimates before work, so you know cost and options up front.

Frequently Asked Questions

Why is my water heater not heating after I reset the breaker?

A tripped breaker usually signals a failed element or wiring issue. If it trips again, stop resetting. You likely need an element replacement or electrical repair.

How long should a 50‑gallon tank take to reheat?

About 45 to 60 minutes for electric and 30 to 40 minutes for gas, depending on temperature rise and model efficiency.

Is 140°F better than 120°F for hot water?

Most homes should use 120°F for safety and energy savings. Higher temps increase scald risk and energy use. Use 140°F only when required and with mixing valves.

Should I repair or replace a 12‑year‑old water heater?

At 12 years, replacement often makes more sense, especially if there is rust, leaks, or repeated part failures. New units are more efficient and reliable.

Do tankless water heaters fix “no hot water” problems?

They do if sized and installed correctly. Tankless units provide endless hot water and fast recovery. Proper gas line sizing and venting are essential.

If your water heater is not heating, start with safe checks for settings, power, ignition, and sediment. When in doubt, call a pro. Summers restores hot water fast and backs every visit with clear estimates and friendly service.
