Most electric tank water heaters use two heating elements and two thermostats, and they take turns rather than running together. The upper thermostat has priority: it heats the top of the tank first, then hands power down to the lower element, which does most of the day-to-day work. Above the upper thermostat sits a high-limit switch, the red reset button, which cuts power if the water ever gets dangerously hot. That arrangement makes symptoms a real clue. No hot water at all usually points to the upper element, the upper thermostat, a tripped high-limit, or the breaker. Hot water that runs out quickly usually means the lower element or lower thermostat has quit. In Lakeville, MN, we see all of these every week.
Electric water heaters are straightforward to test with the right meter and training, and that is exactly how Lakeville Water Heater starts. At each Lakeville home, our technicians measure element resistance, check for elements shorted to the tank, test thermostat operation, confirm the breaker and supply voltage, and inspect every connection from the junction box to the terminals. We also look at sediment. A lower element buried in mineral buildup runs hot, fails early, and can make the tank noisy, so whenever we pull an element, we check how much sediment is sitting on the bottom and flush it out if needed.
The repair itself is usually the easy part. Elements, thermostats, and high-limit switches are standard parts, and our trucks carry the common sizes. Replacing an element means shutting off power, draining the tank, installing the new element, and refilling completely before power is restored, which protects the new element from a dry fire. Damaged wiring, loose terminals, and sediment on the tank bottom are handled in the same visit. If replacement makes more sense, we install new electric heaters sized to your household's first-hour demand, confirm the breaker and wire gauge are correct, and add the expansion tank, drain pan, and strapping your local code requires.

Symptoms That Mean It's Time to Call
A heater that is starting to struggle rarely hides it for long, and the clues are easy to spot once you know them. These are the red flags our technicians see most often before a breakdown:
- A burning smell or a discolored access panel near the thermostat
- Rusty water, leaks around an element, or water at the base
- A tank that has stopped heating completely
- A short burst of hot water, then nothing but tepid
- A hissing or sizzling noise near the lower element
- A breaker that trips when the heater calls for heat
- Water that comes out scalding hot
- The high-limit reset popping again after you push it
A Slow Leak Never Stays Slow
Most water heater failures start small: a popping sound from sediment, a damp spot under the drain valve, or a shower that goes lukewarm a few minutes sooner each week. A quick call to (507) 301-0002 gets a technician out to check it before it becomes an emergency.

What a Trained Technician Brings to the Job
Electric water heaters run on 240 volts, usually on a dedicated 30-amp circuit, and that alone makes them a poor place to learn by trial and error. The thermostats sit right next to live terminals behind the access panel, and a meter probe that slips can cause a dangerous arc. Replacing an element also means draining the tank, and forgetting to refill it completely means the new element burns out the moment power returns. Symptoms also overlap. A tripped reset can come from a stuck thermostat, a grounded element, or a loose connection overheating a terminal, so guessing often replaces the wrong part.
Our technicians work on electric heaters with verified procedures and proper meters. They confirm power is off before touching terminals, test element resistance and ground faults, check thermostat operation, and find the reason a high-limit tripped instead of simply pressing it back in. When an element comes out, they drain the tank, look at how much sediment has settled, flush it if necessary, and refill completely before restoring power. You also get an honest opinion on the heater itself. If the tank is leaking or the heater is past about twelve to fifteen years, you will hear it from us before you spend money on a repair.
Our Electric Water Heater Services Process
We work through a clear, repeatable process so you always know what's happening and what it will cost. Here's how we handle electric water heater services from start to finish:
Circuit & Component Testing
With power safely controlled, we meter the elements, thermostats, and reset switch and inspect the wiring, so the repair targets the actual failure.
Plain Findings & Upfront Quote
Nothing hidden on the invoice. We explain the fault, quote the fix up front, and let you know if replacement is the better value on an aging heater.
Element & Thermostat Repair
Failed elements and thermostats are typically swapped the same visit. We drain and refill the tank properly so a new element is never powered dry.
Tested Before We Leave
We restore power, confirm each element draws current in turn, check the water temperature, and make sure the high-limit stays set.

Tap to Call (507) 301-0002Tips to Keep Your Water Heater Healthy
A few simple habits, like an annual flush and a quick look at the relief valve, can add years to a tank. Start with these practical measures our team relies on:
- Check the T&P relief valve annually, and call if it drips afterward
- Drain a few gallons from the bottom of the tank periodically to control sediment
- Consider a water softener if you have hard water, since it slows sediment and scale on the elements
- If the reset button trips, have it checked rather than pressing it over and over
- Ask for an anode rod check every few years, since the anode is what keeps the tank from rusting
- Keep the thermostats set around 120 degrees to save energy and reduce scalding risk
- Make sure water flows steadily from a hot tap before the heater's power goes back on
Comparing DIY and Professional Work
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. A side-by-side look:
| Consideration | DIY Attempt | Professional Service |
|---|---|---|
| Diagnosis | Replace an element and hope | Meter readings pinpoint the failed part |
| Electrical Safety | Live 240V terminals behind the panel | Circuit tested dead, then work begins |
| Draining & Refilling | Tank not fully refilled before power-up | Tank drained, refilled, and purged of air first |
| Reset Button | Reason for the trip ignored | Stuck thermostat or grounded element traced |
| Sediment | Sediment left burying the lower element | Tank and anode checked during service |
| Outcome | Temporary fix at best | Lasting repair, confirmed by testing |
