An electric water heater does not burn anything, so it is tempting to think nothing much can go wrong. In practice, the parts that do the work (two heating elements, two thermostats, and a high-limit safety switch) fail in predictable ways. The upper thermostat heats the top third of the tank first, then switches power to the lower element. Lose the upper element or thermostat and the lower element never gets power, so the whole tank goes cold. If the lower element burns out, the top of the tank still heats, so you get a short burst of hot water that runs out fast. For Ames, IA homeowners, knowing which symptom you have is the first step toward the right fix.
Ames Water Heater tests electric heaters with a meter, not a hunch. With power confirmed off, our technicians measure element resistance and look for a short to the tank, a common failure that can keep tripping the high-limit. Then, following careful live-testing procedure, we verify voltage at the thermostats and watch how power moves from the upper side to the lower side. We look for scorched wires, melted insulation, and loose terminal screws, since a loose connection can heat up enough to damage the thermostat and the wiring around it. If the reset button has tripped, we find out why before resetting it, because a high-limit that trips is doing its job.
Most electric water heater repairs are finished in one visit. We replace burned-out elements (draining the tank first and refilling it completely before power goes back on, since an element energized in open air burns out in seconds), replace upper and lower thermostats and high-limit switches, repair scorched wiring and loose connections, and flush out sediment that is burying the lower element. When the tank is leaking or the heater has passed about twelve to fifteen years, we tell you honestly and walk you through replacement. New installations include confirming that the circuit, breaker, and wire size match the heater, plus an expansion tank, drain pan, and seismic straps wherever code calls for them. We can also talk through a heat pump water heater if lower operating costs appeal to you. Call (515) 715-4279 and we will get your hot water back.

When to Call for Electric Water Heater Services
A heater that is starting to struggle rarely hides it for long, and the clues are easy to spot once you know them. If any of the following sound familiar, it's worth having the unit checked:
- Browned wiring or a burnt odor from behind the access cover
- Hot water that runs out after just a few minutes
- Dangerously hot water, a sign a thermostat may be stuck
- The water heater breaker tripping over and over
- Rust-colored hot water or moisture around the heater
- A tank that has stopped heating completely
- Popping, sizzling, or crackling sounds from the tank
- A red reset button that keeps tripping
Act Before It Gets Worse
Tanks rarely fail all at once. They corrode from the inside for months, and the warning signs show up long before the floor gets wet. At the first hint of a problem, reach out to Ames Water Heater at (515) 715-4279 and we'll take a look.
Common Questions We Hear
The Benefits of Professional Electric Water Heater Services
Consider the risks first. A standard electric water heater is a 240-volt appliance on a dedicated circuit, and both thermostats sit a finger's width from live terminals. A slipped screwdriver or a missed step in shutting off power can cause a serious shock or an arc flash. Then there is the diagnostic puzzle: no hot water can mean a tripped breaker, a tripped high-limit, a failed upper element, or a bad upper thermostat, and every guess that misses costs you a part and an afternoon. Element replacement adds another trap, because an element powered before the tank is full burns out almost instantly.
What a trained technician brings is certainty. We test instead of guessing, from element resistance and ground-fault checks to thermostat operation and supply voltage. We replace wiring that heat has damaged, tighten or replace terminal connections, and refill the tank completely before power goes on, so a new element is never destroyed by a dry fire. And because some electric heaters are simply worn out, we give you a straight answer on repair versus replacement, including whether a heat pump water heater might make sense for your home.
From Your Call to Hot Water
Our workflow is simple and thorough, so nothing gets missed between the fuel supply and the relief line. Here's a look at each step our team takes:
Circuit & Component Testing
Before a part is ordered, we confirm power at the heater and test each element, thermostat, and connection to pinpoint what stopped the water from heating.
Plain Findings & Upfront Quote
You see the test results, hear the cause in plain terms, and get the price first. On an older tank, we give you an honest repair-versus-replace answer.
Same-Visit Repair
Most fixes are done in one trip. We replace the failed part, repair any heat-damaged wiring, and refill the tank completely before power goes back on.
Full Performance Test
With power back on, we confirm each element draws current in turn, check the water temperature, and make sure the high-limit stays set.

A little routine care goes a long way toward keeping a water heater running well past its expected lifespan. Put these technician-approved steps to work at home:
- Test the temperature and pressure relief valve once a year
- If the reset button trips, have it checked rather than pressing it over and over
- Replace a worn anode rod before corrosion moves on to the tank itself
- After any draining, refill the tank fully and run a hot faucet before restoring power
- Keep the thermostats set around 120 degrees to save energy and reduce scalding risk
- Protect your elements from hard water with a softener or upgraded low-watt-density elements
- Flush sediment from the tank once or twice a year so it cannot bury the lower element
DIY vs. Professional Electric Water Heater Services
Online videos may help in a pinch, yet lasting repairs and code-compliant installs depend on correct venting, proper relief valve discharge piping, and a trained technician. Consider the following comparison:
| Factor | Doing It Yourself | Professional Service |
|---|---|---|
| Diagnosis | Replace an element and hope | Every element and thermostat metered |
| Electrical Safety | Working near 240V without verifying it is off | Power verified off before any work |
| Draining & Refilling | Tank not fully refilled before power-up | Proper gasket seal and full refill |
| High-Limit Trips | Reason for the trip ignored | Cause of the trip found and fixed |
| Tank Condition | Sediment left burying the lower element | Tank and anode checked during service |
| Outcome | Symptom patched, cause remains | Real fault repaired and tested |
