RV Water Heater Repair - Fort Lauderdale FL

The three most common issues we see in Broward County: anode rod failure causing rotten egg smell from hot water (Florida's hard water reacts with the standard magnesium anode to produce hydrogen sulfide), electric heating element failure from mineral scale buildup coating the element and causing it to burn out, and propane DSI igniter failure from Florida's humidity corroding the igniter probe. All three are same-day repairs we carry parts for.

Annually. Florida's hard water causes magnesium anode rods to corrode much faster than in softer-water states. A magnesium anode that might last 2 to 3 years in the Midwest may be severely depleted within 12 to 18 months in Broward County. Switching to an aluminum/zinc anode rod is also recommended - it reacts less with Florida's sulfur mineral content and produces less of the rotten egg odor common with magnesium anodes in hard water.

Popping and rumbling sounds from an RV water heater are caused by mineral scale deposits on the heating element or the tank bottom. When the electric element heats, the scale expands and contracts, making these sounds. Eventually, the scale coating insulates the element from the water, causes it to overheat, and burns it out. An annual anode rod replacement and periodic tank flush removes scale before it reaches this stage.

We service Atwood (now Dometic) and Suburban water heaters, which together account for the vast majority of RV water heaters in Broward County. These are available in 6-gallon and 10-gallon sizes, in propane-only, electric-only, and dual-fuel (propane and electric) configurations. We carry the most common elements, anodes, and DSI control boards for these brands in our service vehicles.

Water heater diagnosis runs $89 to $149. Anode rod replacement runs $95 to $175. Electric element replacement runs $125 to $225. DSI ignition board replacement runs $145 to $295. Full water heater replacement runs $450 to $850 including the new unit and installation labor.

Yes. Tankless (on-demand) RV water heaters from Girard and Truma are increasingly common in newer RVs. They heat water only when a hot water tap is opened. Common issues include ignition failures (similar to standard water heaters), heat exchanger scale buildup from hard water, and flow sensor failures. Girard and Truma units have their own service procedures that our technicians are trained on.

A water heater that heats slowly typically has a heating element partially coated with mineral scale that reduces its effective wattage. A 1,440-watt element that is 50% coated with scale produces only 720 watts of effective heat output. Annual element inspection and descaling or replacement restores proper heating time. Running only propane mode (which uses a burner rather than an element) avoids the scale problem but depends on propane availability.

Yes. After 3 or more months of storage in Florida's warm climate, the water heater tank should be drained and refilled with fresh water before use. Stagnant water in the tank can harbor bacteria including Legionella in the warm Florida environment. Drain the tank completely, refill, heat to 120 degrees for 30 minutes to kill any remaining microorganisms, then use normally.

Yes. RV water heaters are designed to be serviced through the exterior access door without major disassembly of the RV interior. Anode rod replacement, element replacement, and even full water heater replacement are all performed through the exterior panel. This makes water heater service one of the easier RV repairs to perform at a campsite.

120 degrees Fahrenheit is the standard recommendation - it provides scalding-hot water for showers and cleaning, is hot enough to kill most bacteria, and is low enough to reduce element scale buildup compared to higher settings. In Florida's warm climate, incoming water is often already 75 to 80 degrees, so the water heater needs less heating energy than in northern states - one of the few climate advantages for RV owners in Broward County.
