Fixing Your RV Water Heater Not Working on Electric
It's a huge bummer if you realize your own rv water heater not working on electric is definitely standing between a person and a hot shower after the long day on the street. Most of us rely on that electric heating system element to conserve our propane regarding cooking or keeping the rig cozy, so when it quits, it's more than just a minor inconvenience. The great news is that while it feels such as a major disaster, the fix is usually something you can handle yourself with no having to drag the whole rig to some service middle.
Before a person start panicking about the cost of the new unit, let's walk through what's likely going on. RV water heaters are pretty simple devices, but they have a few "gotchas" that may trip up actually experienced campers.
Check the Most Obvious Stuff Initial
I realize this sounds silly, yet you'd be amazed how often the solution is just a switch someone forgot to flip. Many RV water heating units, especially the popular Suburban models, have two switches. There's usually one within your control panel, but there's often a secondary "hidden" switch situated behind the outdoor access door associated with the water heater itself.
Go outside, take that panel open, and look intended for a small dark rocker switch. It's often tucked apart within the bottom remaining corner, sometimes at the rear of the gas control device piping. If that will switch is off, your electric component isn't getting any kind of juice, no matter what the inside of panel says. This switch is right now there as a basic safety measure to prevent the element from burning out when the tank is definitely empty, like during winterization.
Whilst you're checking fuses, take a quick peek at your own main breaker panel inside the RV. Appear for the breaker labeled "Water Heater. " Flip this all the method off and then back on once again. Sometimes a breaker can trip simply enough to cut power without searching obviously out of place.
The Shore Power Link
If your rv water heater not working on electric is usually a new problem that just started at a particular campsite, the problem might not be your RV at all. Electric water heaters pull the lot of amps. If the pedestal at the campground is usually sketchy or in case you're running your AC and microwave at the same time, you may be pushing the limits associated with your 30-amp or 50-amp service.
If you're using a 15-amp or 20-amp adapter to plug within at home, there's a very good chance the water heater won't possess enough "oomph" to get going, or it might trip a breaker immediately. Always make sure you have got a solid, clean connection to coast power before a person start tearing into the appliance itself.
The Notorious Heating Element
If the changes are on plus the breakers are usually fine, we're relocating into the most common hardware failure: the electric heating element. This small metal coil will be what actually gets hot to warm up your water.
The greatest enemy of the particular heating element will be "dry firing. " If you (or the previous owner) turned on the electric switch while the water heater tank was empty—even for just ten or twenty seconds—that element is bread toasted. Without water in order to dissipate the temperature, the element will get so hot it literally cracks or even burns itself away almost instantly.
In order to check this, you'll need a multimeter. Make sure the power is completely away from (unplug the RV or flip the breaker). You'll find the element at the rear of a small screw on cover on the face from the heater. Disconnect the cables and look for continuity. If your meter shows "open" or even infinite resistance, the particular element is lifeless. Luckily, these are cheap and a person can find replacements at almost any kind of hardware store; just make sure you obtain the right wattage and also a socket wrench long enough to reach it.
Resetting the ECO and Thermostat
At the rear of that same exterior panel, you'll notice a rubber cover up (usually shaped like a circle or an oval) that states "Reset. " Underneath that cover are your thermostats as well as the Emergency Cut Away (ECO). These are usually basically high-limit fuses designed to eliminate the power in the event that the water will get dangerously hot.
Sometimes, for no apparent reason, these types of switches trip. This could be the hot day, or maybe the water just got the little too warm. Give those buttons a firm press. If you hear a click, you've probably found your problem. In the event that they keep tripping, it's an indication that your thermostat is failing and believes the water is definitely hotter than it actually is, or it's actually allowing the water obtain too hot, which is a safety hazard. In either case, replacing the thermal assembly is a pretty straightforward DO-IT-YOURSELF job.
Cabling and Corroded Cable connections
RVs are usually basically houses that will endure a continuous earthquake each time you drive down the particular highway. Things shake loose. If you've checked the element and the fuses, it's time in order to look at the wiring.
With the power off, search for any indicators of charred cables or melted plastic material near the heating element or the particular reset buttons. Sometimes a wire enthusiast vibrates loose, or a connection gets a bit associated with corrosion from being outside. A shed wire creates level of resistance, resistance creates high temperature, and heat touches things. If a person see a wire that looks crispy, that's your smoking gun. You'll need to strip back the particular bad wire and set on a brand-new connector.
The particular Control Board and Relays
When you've got an Atwood (now Dometic) water heater, the particular setup is the bit different compared to the Suburban types. A number of these use a 12V DC transmission to trigger the 120V AC relay. This means your inside switch transmits a tiny little bit of battery strength to a relay, which then "closes the particular gate" to allow the big coast power reach the heating element.
If that exchange is bad, the element never will get power. You may usually find the particular relay within a junction box on the back of the particular water heater unit, which usually means moving under a cabinet or by way of a storage bay. It's a bit of a discomfort to get to, but in the event that you're getting energy at the change but not in the element, the relay is the middleman that's likely failing.
Don't Forget about the Bypass Control device
Will be the water actually cold, or are you simply not getting sizzling water at the particular tap? It seems like a question, but it's a true thing. If your own water heater circumvent valves (the ones you utilize for winterizing) are usually in the incorrect position, you might be mixing up cold water directly into your hot water line.
This often happens right after the first trip of the spring. You think your rv water heater not working on electric is the particular problem, but actually, the heater will be working perfectly fine—it's just that the very hot water is being clogged or diluted simply by the bypass. Double-check those valves at the rear of the heater to ensure they're pointing the proper way.
Why Servicing Matters
To keep this from occurring again, there are a few things you should do. First, always, always make sure the tank contains large amount just before you flip that will electric switch. I turn on a hot water tap and wait intended for a steady stream of water (no atmosphere bubbles) before I actually even think regarding the heater.
Second, if you're in an region with hard water, minerals will create up on that electric element. This makes it function harder and eventually causes it to fail. Flushing your own tank a few times a year with the wand and some vinegar can help you save a lot of headache down the line. It's the messy job, but it beats taking cold showers in the middle of the woods.
Wrapping It Up
Living the particular RV life is all about rolling with the your punches, and a broken water heater is just one of those things that's guaranteed to happen eventually. Most of the particular time, your rv water heater not working on electric is caused by a tripped breaker, a concealed switch, or perhaps a burnt-out element.
Take it one step at the time. Begin with the particular easiest stuff—the switches—and work your method toward the more technical parts like the element or the control board. More frequently than not, you'll have that water steaming hot once again before the sunlight goes down, and a person won't need to spend a fortune at the repair shop to do it. Remember to stay secure, maintain the power off while you're poking around, and enjoy that hot shower once you get it sorted!
