Estimated Read Time: 11 minutes

When a water heater not working derails your day, you want fast answers that actually fix the problem. This guide breaks down the seven most common causes and what to try first. You will see easy checks you can do safely, when to call a pro, and how to prevent the same issue from coming back. Live in the Indianapolis area? Watch for local tips on hard water, winter freeze risks, and current coupons to save on service.

1) No Power or Gas Supply Reaching the Heater

If your water heater is completely dead, start by verifying that it is getting energy. Electric units need a live circuit. Gas units need the gas supply on and proper ignition.

What to check now

1. Electric models
2. • Inspect the breaker panel for a tripped breaker. Fully switch it off, then back on.
   • Check the dedicated shutoff switch near the unit.
   • Press the high-limit reset button on the upper thermostat behind the access panel.
2. Gas models
3. • Confirm the gas valve is in the On position.
   • Make sure the shutoff valve on the gas line is parallel to the pipe.
   • If you smell gas, evacuate and call the gas company or a licensed pro.

When to call a pro

• Breakers that trip repeatedly indicate a failing heating element, shorted wiring, or control board issues.
• Gas supply or ignition problems require proper testing for safety.

Local insight: In winter, Indianapolis basements can dip low enough to stress older breakers and uninsulated lines. Keep the area around the heater clear for ventilation and easy access.

2) Pilot Light Out or Ignition Failure (Gas Heaters)

No hot water or frequent shutdowns often trace back to the pilot or ignition. Dirt, weak flame, or a faulty thermocouple can stop the burner from staying lit.

DIY steps

1. Check the sight glass. If the pilot is out, follow the lighting instructions on the unit label.
2. Verify the gas control is set to Pilot, then Hold. Use the igniter per instructions.
3. If the pilot will not stay lit, the thermocouple or flame sensor may be fouled or failing.

Professional fixes

• Clean or replace the thermocouple or flame sensor.
• Adjust gas pressure and check combustion air.
• Inspect venting for blockages that starve the flame of oxygen.

Safety callout: Soot, lazy yellow flames, or repeated ignition failures can point to unsafe combustion. Have a licensed technician test draft and carbon monoxide risk immediately.

3) Faulty Thermostat or Heating Elements (Electric Heaters)

Lukewarm or rapidly cooling water often means a bad thermostat or a burned-out heating element. Electric tanks have upper and lower components that work together.

What you can do

1. Turn power off at the breaker before opening any panel.
2. Remove access panels and insulation. Press the reset on the upper thermostat.
3. If problems return, elements or thermostats likely need testing with a multimeter and replacement.

Pro solution

• We test resistance and continuity on elements and run-load checks on thermostats.
• If wiring is brittle or scorched, we replace with rated parts and confirm tight, corrosion-free connections.

Prevent it next time

• Annual service catches failing components early and reduces electrical stress, especially after heavy holiday use.

4) Sediment and Scale Buildup From Hard Water

In Central Indiana, hard water leaves mineral scale that settles at the bottom of tanks and coats heat exchangers in tankless units. Symptoms include rumbling noises, longer heat times, and inconsistent temperatures.

DIY steps for tank models

1. Shut power or gas off. Close the cold supply. Connect a hose to the drain valve.
2. Drain several gallons until water runs clearer. Refill and test.

Why service matters for tankless

• Tankless units require periodic descaling to remove mineral buildup. Without it, you get temperature swings and error codes.

Professional maintenance

• Tank flush and anode inspection for tanks.
• Full tankless descaling, filter cleaning, and safety checks. Most manufacturers require proof of regular professional service to keep warranties valid.

Local insight: Our limestone-heavy water accelerates scale. Homes near Geist Reservoir and well-fed properties often need more frequent flushes.

5) Temperature Set Wrong or T&P Valve Problems

If water is too hot, too cool, or surging in pressure, the thermostat setting or the temperature and pressure relief valve could be to blame.

Quick checks

1. Confirm temperature is set near 120 F for safety and efficiency.
2. Test hot at the farthest faucet. If it is scalding, lower the setting and retest.
3. If the T and P valve drips occasionally during heat cycles, that can be normal. Continuous discharge means a pressure or temperature control issue.

Pro diagnostics

• We test incoming water pressure, expansion tank charge, and the T and P valve function.
• We correct thermal expansion problems that can damage fixtures and the heater.

Why it matters

• A sticking thermostat or failed T and P valve is a safety risk. Replace faulty parts promptly.

6) Leaks, Rust, and Anode Rod Failure

A little moisture might only be condensation, but active leaks deserve attention now. Left alone, leaks can cause structural damage and mold.

What to look for

• Water around the base, corrosion on fittings, or rust-colored water.
• Drips from the drain valve, inlet, or outlet connections.

DIY triage

1. Tighten accessible connections gently. Do not overtighten plastic valves.
2. If the tank body is leaking or heavily rusted, replacement is the safe move.

Pro repair or replace

• We replace worn anode rods to slow internal corrosion.
• We swap faulty valves, repair piping, and install expansion tanks where needed.
• If the tank is compromised, we size and install a new unit with code-compliant venting and seismic strapping where applicable.

7) Wrong Size or End-of-Life Equipment

If your family grew or you added a soaking tub, the same heater may no longer keep up. Most standard tanks last about 8 to 12 years. Tankless models can last up to twice as long with proper maintenance.

How to tell it is time

• Frequent cold showers, slow recovery, or a unit older than 10 years.
• Repeated repairs that outpace the value of the heater.

Your upgrade options

• High-efficiency tank models with better recovery.
• Tankless for endless hot water, space savings, and lower utility bills.
• Hybrid solutions where electric rates make heat pump water heaters attractive.

Why choose a pro install

• Correct sizing based on peak demand and recovery rate.
• Code-compliant venting, gas sizing, and condensate management.
• Manufacturer-validated startup so your warranty is protected.

Frequently Asked Questions

Why is my water heater not working after a power outage?

Power surges can trip the breaker or the high-limit switch. Reset the breaker and press the heater’s reset button. If it trips again, call a licensed tech to test elements and wiring.

How often should I flush my water heater in Indianapolis?

With our hard water, flush tank models at least once a year. Tankless units need annual descaling. Homes with very hard water or well systems may need service every 6 to 9 months.

Is 120 F hot enough for my home?

Yes for most homes. It helps prevent scalds and reduces energy use and scale formation. If you have a dishwasher without a heater, ask a pro before increasing the setting.

When should I repair instead of replace?

If the unit is under 8 years old and the tank is sound, repairs often make sense. If it leaks from the tank or is 10 to 12 years old with recurring issues, replacement is usually smarter.

Are tankless water heaters worth it in Central Indiana?

Yes for many families. You get endless hot water, space savings, and lower utility bills. With proper maintenance, tankless systems can last up to twice as long as a standard tank.

Bottom Line

If your water heater is not working, start with simple checks, then move to safe DIY steps. For ignition failures, electrical faults, leaks, or scale, a licensed pro saves time and protects your warranty. In Indianapolis, hard water and winter temps make maintenance essential.
