Few things are worse than taking a shower while camping and finding out there’s no hot water in your RV. While RVs are designed for a comfortable life on the road, issues with getting hot water can put a damper on your travels. But before you panic, let’s explore some possible reasons behind why your RV water isn’t hot.
Cold showers in an RV can be caused by various factors, ranging from a tripped breaker to a faulty thermostat. Blocked valves or a propane tank shutoff might also be the cause, among other issues. Understanding these causes can help you identify the problem and fix it, allowing you to enjoy the warmth that a hot shower provides once again.
Dealing with no hot water in an RV doesn’t have to be a stressful experience. With the right information and a little patience, you can troubleshoot the issue and get your hot water flowing again in no time.
Let’s dive deeper into the common reasons behind this problem and some simple fixes to get your RV’s hot water back on track.
Common Causes of No Hot Water in RV
Your Bypass or Crossover Valves Are Set Incorrectly
One possibility for no hot water in your RV could be due to the bypass or crossover valves being set incorrectly. These valves are usually located near the water heater tank and are used to allow water to bypass the tank during winterization. Make sure they are in the appropriate position (parallel with the water lines) for normal operation.

Your RV’s Main Power Switch Is Off
Another reason for no hot water might be that your RV’s main power switch is off. Check if it’s turned off, and be sure to switch it on for both the electrical and gas supply to your water heater.
The Water Heater Circuit Breaker Is Tripped
A tripped water heater circuit breaker could be the culprit behind your problem. This often happens due to power surges or overloads. Check your RV’s electrical panel and reset the breaker if necessary.
Your Propane Tank Is Turned Off
If your water heating system runs on propane, ensure that your propane tank is turned on. Also, inspect the gas line for any blockages or damage that could impede the flow of gas.
You’re Low Or Out Of Propane
Low propane levels or an empty tank can prevent your water heater from working properly. Check your propane level and refill the tank if needed.

You Left The Hot And Cold Faucets Open Somewhere (Like Your Outside Shower)
Leaving a faucet open, such as your outside shower, can cause hot and cold water to mix, resulting in lukewarm or poorly heated water. Double-check your faucets and ensure they are all closed.
The Hi-Limit or Emergency Cut-Off Switch Needs To Be Reset
The hi-limit or emergency cut-off switch, which protects your water heater from overheating, might have been triggered. Locate the switch near the thermostat or gas valve, and reset it according to the manufacturer’s instructions.
Your Electric Heating Element Might Be Bad
An electric heating element may be faulty or burnt out, preventing your water heater from working properly. To determine if the element needs to be replaced, test it using a multimeter, or seek the help of an RV technician.

The Thermostat Could Be Faulty
A thermostat that doesn’t regulate temperature correctly can cause issues with your water heater. Inspect the thermostat for signs of wear, damage, or a loose connection. If it’s faulty, consider replacing it to ensure proper water heating.
Frequently Asked Questions
There could be several reasons for your RV water heater not working on electric or gas. First, check if it’s switched on and connected to a power source. If it’s on propane mode, ensure that propane levels are sufficient. For electric mode, verify that the shore power is correctly plugged in. In case the problem persists, there might be an issue with your water heater’s bypass valves, thermostat, or fuse.
To turn on hot water in your RV, locate the water heater switch (usually inside your RV) and set it to the “On” position. If your water heater has a gas or electric mode, select the desired operation source. Ensure your propane or electric connection is functional to heat the water. Allow a few minutes for the water to heat up.
The reset button, also known as the Hi-Limit/E.C.O. button, is usually located on your RV water heater’s exterior housing. Access it by opening the water heater door on the outside of your RV. Look for a small black or red button, and press it to reset the water heater. If the issue persists, consult your water heater manual for specific instructions on your model.
Yes, there’s generally a fuse involved in the hot water heater operation of an RV. Check your RV’s electrical panel to locate and inspect the corresponding fuse. If it’s blown, replace the fuse to restore the hot water heater’s functionality. Remember that a blown fuse can be a symptom of an underlying issue – if it blows again, consult an RV technician.
Activating your camper’s hot water heater requires turning it on using the dedicated switch located inside your RV. Select either gas or electric mode, depending on your heater type and available power source. Make sure to maintain sufficient propane levels if you’re using gas mode and ensure a proper electric connection for electric mode.
The thermostat of your RV’s water heater typically lies behind the exterior access door of your water heater unit. It’s mounted on the heater’s tank. Occasionally, the thermostat may be obscured by an insulation cover, requiring you to remove the cover first to access it. Consult your water heater manual for instructions specific to your model.
