Water Heater Not Heating? Element Replacement in Phoenix, AZ | Mountain Vista Plumbing
When Your Water Heater Stops Working, It's Not Always Time for a New One
Losing hot water entirely can feel like an emergency that requires a full water heater replacement. But that's not always the case. We recently helped a Phoenix homeowner whose electric water heater had stopped working completely, and the fix turned out to be more straightforward than expected.
What We Found
After inspecting the unit, our team diagnosed the problem: both the upper and lower heating elements had failed. Electric water heaters rely on these elements to heat the water inside the tank, and when one or both fail, the unit can stop producing hot water altogether or struggle to keep up with household demand.
How We Fixed It
Rather than replacing the entire unit, our team removed and replaced both the upper and lower heating elements, restoring the water heater to full working order. This repair got the homeowner back to reliable hot water at a fraction of the cost of a full water heater replacement, which isn't always necessary when the tank itself is still in good shape.
Why Heating Elements Fail
Heating elements are one of the most common failure points on electric water heaters, and Arizona's hard water (15+ GPG) plays a significant role in that. Mineral buildup and sediment inside the tank can coat the elements over time, forcing them to work harder to heat the water and shortening their lifespan considerably. This is a different failure mode than what we saw recently with a severely corroded water heater in Gilbert, where the tank itself was compromised rather than just the elements — which is why an accurate diagnosis matters before deciding on a repair versus a replacement.
Signs Your Water Heater May Have a Failed Element
No hot water at all
Hot water that runs out much faster than usual
Water that takes longer than normal to heat up
A water heater that trips the circuit breaker repeatedly
If you're experiencing any of these issues, it doesn't necessarily mean you need a new water heater. Having the unit properly diagnosed can save you the cost of an unnecessary replacement.
