Common Issues
Is your RV hot water heater not working on electric? You are not alone. RV owners often face this issue. Let’s explore the common problems. This can help you identify and fix the issue. Here are the most common problems:
Power Supply Problems
A faulty power supply can be a major cause. Check if the power is reaching the heater. Ensure the circuit breaker is not tripped. Use a multimeter to test the outlet. If the outlet has no power, there might be wiring issues. Inspect the connections for loose wires. Tighten them if needed. Replace damaged wires to ensure a steady power supply.
Thermostat Malfunctions
The thermostat controls the temperature of the water. If it malfunctions, the water may not heat up. Test the thermostat with a multimeter. Check for continuity. If there’s no continuity, the thermostat is likely faulty. Replace it with a new one. Ensure the new thermostat is compatible with your heater. Follow the manufacturer’s instructions for installation.
Heater Element Failures
The heating element is crucial for water heating. If it fails, the water stays cold. Use a multimeter to check the heating element. Test for continuity. A lack of continuity means the element is defective. Replace the faulty heating element. Ensure the new element matches your heater’s specifications. This helps avoid future issues.

Initial Troubleshooting
Is your RV hot water heater not working on electric? Start by troubleshooting the issue. A few simple steps can help identify the problem. Follow these basic checks to get your hot water flowing again.
Check Circuit Breaker
First, check the circuit breaker. Go to your RV’s electrical panel. Look for the breaker labeled “water heater.” Ensure it is in the “on” position. If it has tripped, reset it by flipping it off and then on again. This might solve the issue.
Inspect Power Connections
Next, inspect the power connections. Ensure the RV is connected to a power source. Verify the plug is securely in the outlet. Check for any visible damage to the power cord. Look for loose or frayed wires. Damaged cords can prevent power from reaching the heater.
Reset The System
Finally, try resetting the system. Many RV water heaters have a reset button. Locate it on the heater, often near the thermostat. Press and hold the reset button for a few seconds. This can often reset the system and resolve the problem.
Testing The Thermostat
When your RV hot water heater isn’t working on electric, testing the thermostat is crucial. The thermostat controls water temperature. If it’s faulty, it can cause the heater to malfunction. Here’s a step-by-step guide to help you test your RV hot water heater’s thermostat.
Locate The Thermostat
The first step is to locate the thermostat. It’s usually behind a metal cover on the water heater. To access it, you’ll need to remove the cover using a screwdriver.
- Turn off the power to the water heater.
- Remove the screws holding the cover in place.
- Lift off the cover to expose the thermostat.
Use A Multimeter
Next, you’ll need to use a multimeter to test the thermostat. A multimeter measures electrical resistance and can help determine if the thermostat is working properly.
- Set the multimeter to the lowest ohms setting.
- Touch one probe to a terminal on the thermostat.
- Touch the other probe to the other terminal.
- Check the reading on the multimeter.
If the reading is zero or infinity, the thermostat is faulty and needs replacing.
Replace If Necessary
If the thermostat is faulty, it’s important to replace it to restore your hot water heater. Replacing the thermostat is a straightforward process.
- Purchase a new thermostat compatible with your water heater model.
- Turn off the power and water supply to the heater.
- Remove the faulty thermostat by disconnecting the wires.
- Install the new thermostat by connecting the wires to the correct terminals.
- Replace the cover and secure it with screws.
Turn the power and water supply back on. Your hot water heater should now work on electric.
Inspecting The Heater Element
Inspecting the heater element is crucial if your RV hot water heater is not working on electric mode. A faulty heater element can disrupt the entire system. Follow these steps to inspect the element.
Access The Element
To access the heater element, first turn off all power to the RV. Locate the water heater panel. Use a screwdriver to remove the panel cover. This exposes the heater element and its connections.
Check For Continuity
Using a multimeter, set it to the ohms setting. Place the probes on the terminals of the heater element. A reading of zero or infinity indicates a faulty element. A reading between 10 to 20 ohms is usually normal.
Replace If Faulty
If the element is faulty, it needs replacement. Drain the water heater to prevent leaks. Disconnect the wires from the heater element. Use a wrench to remove the old element. Install the new element, ensuring a tight fit. Reconnect the wires and replace the panel cover.
After replacing, turn the power back on. Check if the heater is working properly. If the problem persists, further inspection may be needed.
Cleaning The Tank
Maintaining your RV hot water heater is crucial for its efficiency. One key step is cleaning the tank. Over time, sediment and mineral build-up can occur, affecting the performance. Here’s a simple guide to help you clean your RV hot water heater tank.
Drain The Water Heater
First, turn off the power supply to the water heater. Next, open the pressure relief valve to release any built-up pressure. Place a bucket under the drain valve. Open the drain valve and let the water flow out completely. This step ensures that you remove all the old water.
Remove Sediment Build-up
Once the tank is empty, it’s time to tackle the sediment. Use a cleaning wand specifically designed for water heaters. Insert it into the tank through the drain valve. Turn on the water supply and flush out the sediment. Move the wand around to ensure you reach all areas inside the tank. Repeat this process until the water runs clear.
Refill And Test
After removing the sediment, close the drain valve. Turn off the pressure relief valve. Open the cold water supply and let the tank refill. Once full, turn on the power supply. Wait for the water to heat up. Finally, test the water heater by running hot water from a faucet. Ensure it works efficiently and heats up as expected.

Checking Electrical Connections
Experiencing issues with your RV hot water heater not working on electric? One of the first steps to troubleshoot is checking the electrical connections. This process can help identify and fix common problems. Let’s dive into inspecting wiring, tightening loose connections, and looking for corrosion.
Inspect Wiring
Begin by inspecting the wiring. Ensure all wires are intact and connected. Look for any signs of damage. Damaged wires can disrupt the flow of electricity. Replace any damaged wires you find.
Tighten Loose Connections
Loose connections can cause your RV hot water heater to malfunction. Use a screwdriver to tighten any loose connections. A secure connection ensures proper electrical flow. Double-check all screws and nuts.
Look For Corrosion
Corrosion can impair electrical connections. Check for any green or white buildup on wires and terminals. Clean any corrosion using a wire brush. Apply a protective coating to prevent future corrosion.
