Water Heater No Hot Water repair in Orlando, FL

Verified against official sources · Updated 2026-07-09

Thinking about a water heater no hot water repair in the Orlando area? Here's what actually matters — permit rules for Orange County and the City of Orlando, plus the mistakes and code requirements that trip up homeowners, sourced from manufacturer manuals and the Florida Building Code.

Do you need a permit?

It depends on the exact scope. Orange County and the City of Orlando require permits for more than most homeowners expect — and the rules change. Check the county's official "Do I Need a Permit?" page or call your local building department before starting work.

Key facts before you start

No hot water on an electric unit: check the dedicated 240V breaker FIRST and reset it once — a breaker that trips again is a fault, so stop there. A.O. Smith: 'For electric water heaters, check the circuit breaker first to see if it's tripped, then reset it if needed.' Before opening any access panel, shut the breaker OFF and confirm it's dead — 'High-voltage electricity can kill, and water heater components remain live even when the unit isn't actively heating.' (A.O. Smith)
Reset the high-limit safety the right way: turn power off, then remove the access panel covering the UPPER thermostat to reach the red reset button (ECO / Energy Cut Off) and 'press the reset button firmly until you hear it click.' A click means the water overheated and tripped the cutoff — 'often due to a grounded heating element or a faulty lower thermostat.' Resetting clears the trip but does not fix that root cause. (A.O. Smith)
Do NOT keep re-pressing an ECO button that trips again — A.O. Smith: 'If the button trips repeatedly or you're uncomfortable performing these steps, contact a professional as repeated tripping indicates serious problems like shorted elements or faulty thermostats.' A repeatedly tripping high-limit is a failed-component signal, not a reset to keep chasing; replace the failed element/thermostat or call a licensed pro. (A.O. Smith)
Pin the culprit before buying parts (A.O. Smith Technical Bulletin 36, 'Not Enough Hot Water - Electric'): set both thermostat dials to 130°F, run about 15 gallons, and the water 'should fall between 120°F to 140°F' — if not, check the thermostats. Then keep drawing hot water; if the later reading falls more than 30°F below that, the bulletin says 'check the lower element for continuity and the dip tube.' Test each element for continuity across its two terminals with the meter on its lowest ohms range, power OFF. (A.O. Smith Bulletin 36)
Repairable part vs dead tank: a failed heating element 'can cause you to have some hot water, but not enough' and swaps out cheaply — but 'if your water heater is more than 10 years old, leaks around the base of the tank or operates erratically, it's probably time to replace your water heater.' A.O. Smith puts average life at 'about 8 to 12 years.' Leaks at the base of the tank are a dead-tank sign no element or thermostat fixes. (A.O. Smith)
The element / thermostat / ECO repair (breaker OFF) is minor work — but a full TANK replacement is not casual DIY in Orlando: Orange County states 'Water heater? Yes, you need a plumbing permit and possibly an electrical permit.' — the same PERMIT REQUIRED rule as a new install. Route the tank swap and any 240V wiring change to a licensed pro.
