How To Restart A Rheem Water Heater

Okay, folks, let's talk about something thrilling! (Yes, I'm being sarcastic, but stick with me!). We're going to delve into the surprisingly empowering world of restarting a Rheem water heater. Why empowering? Because nobody likes a cold shower, and knowing how to fix it yourself? That's pure, unadulterated win. You'll be like a superhero of hot water, saving the day, one pilot light at a time.
Now, I know what you're thinking: "Water heaters? That sounds complicated and possibly explosive!" Fear not, intrepid homeowner! While safety is always paramount (we'll get to that!), restarting a Rheem water heater is often much simpler than you imagine. In fact, it's usually just a few easy steps. Think of it as a fun little puzzle, and the prize is a luxurious, steamy shower. Ready to become a plumbing pro? Let's dive in!
First Things First: Safety, Safety, Safety!
Before we even think about touching anything, let's talk safety. We're dealing with gas and electricity here, so a healthy dose of caution is key. Treat this like you're defusing a tiny, lukewarm bomb (okay, maybe not that dramatic, but you get the idea!).
Must Read
Here's your safety checklist:
- Turn off the gas: This is crucial. Locate the gas shut-off valve – it's usually a yellow handle near the water heater. Turn it to the "off" position (usually perpendicular to the gas pipe). No gas, no explosions. Makes sense, right?
- Turn off the electricity (for electric heaters): Find the circuit breaker that controls your water heater and flip it to the "off" position. Double-check it's off. We don't want any unexpected zaps!
- Ventilate the area: If you smell gas (even a faint whiff), open windows and doors to ventilate the area. Get some fresh air circulating. Don't use any electrical devices (including your phone!) until the smell is gone.
- If you smell a strong gas odor or are unsure about anything, call your gas company or a qualified professional immediately.Seriously. Don't mess around with gas if you're not comfortable.
Got it? Great! Now that we've covered the serious stuff, we can move on to the fun part (well, the slightly less serious part).
Identifying Your Rheem Water Heater Type
Rheem makes different types of water heaters, and the restarting procedure can vary slightly depending on the model. So, before we get too far, let's figure out what kind you have.

Look for the model number. It's usually on a sticker or plate on the side of the water heater. Once you have that, you can easily Google it to find the specific instructions for your model. But for now, let's cover the basics for the two main types:
- Gas Water Heaters: These use natural gas or propane to heat the water. They typically have a pilot light that needs to be lit.
- Electric Water Heaters: These use electric heating elements to heat the water. They don't have a pilot light.
Simple, right? Now that you know what you're dealing with, let's get to the restarting process.
Restarting a Gas Rheem Water Heater: The Pilot Light Dance
Okay, time for the main event! Restarting a gas water heater usually involves relighting the pilot light. Don't worry, it's not as scary as it sounds. Here's a step-by-step guide:
- Locate the gas control valve. This is usually a knob or dial near the bottom of the water heater. You'll see markings like "Pilot," "On," and "Off."
- Turn the gas control valve to the "Pilot" position. You might need to push the knob in while turning it. This allows gas to flow to the pilot light.
- Press and hold the reset button (or igniter button). This button releases gas and creates a spark to light the pilot light. You'll need to hold it down for a few seconds (usually 30-60 seconds) while the pilot light ignites.
- While holding the reset button, use a long lighter or match to light the pilot light. Carefully insert the lighter or match into the pilot light opening (you'll see a small hole near the gas control valve). You should see a small flame ignite.
- Keep holding the reset button for another 30-60 seconds. This allows the thermocouple (a safety device) to heat up and keep the pilot light lit.
- Release the reset button. If the pilot light stays lit, congratulations! You've successfully relit the pilot light. If it goes out, repeat steps 3-6.
- Turn the gas control valve to the "On" position. Now your water heater should start heating water again.
Important notes for gas water heaters:

- If the pilot light won't stay lit, the thermocouple might be faulty. This is a common problem, and replacing the thermocouple is usually a relatively easy and inexpensive fix.
- If you smell gas while trying to light the pilot light, stop immediately! Turn off the gas, ventilate the area, and call a qualified professional.
See? Not so bad, right? You're practically a water heater whisperer at this point!
Restarting an Electric Rheem Water Heater: Simple but Important Checks
Restarting an electric water heater is usually much simpler than restarting a gas water heater. There's no pilot light to worry about! However, there are still a few things you need to check.
- Check the circuit breaker. Make sure the circuit breaker for the water heater is in the "on" position. If it's tripped, reset it by flipping it to the "off" position and then back to the "on" position.
- Check the thermostat. Make sure the thermostat is set to a reasonable temperature. A setting of around 120 degrees Fahrenheit is usually sufficient.
- Check for power. Use a multimeter to check that the water heater is receiving power. If it's not, there might be a problem with the wiring or the circuit breaker.
- Check the heating elements. If the water heater is receiving power but not heating water, the heating elements might be burned out. You can use a multimeter to test the heating elements.
Important notes for electric water heaters:

- Never work on an electric water heater while it's plugged in. Always turn off the power at the circuit breaker before doing any work.
- If you're not comfortable working with electricity, call a qualified electrician.
While electric water heaters don't have pilot lights, they can still have issues. If you've checked the breaker and thermostat, and you're still not getting hot water, it might be time to call in a professional. But hey, you've already eliminated a few potential problems yourself! That's still a win!
Preventative Maintenance: Keeping the Hot Water Flowing
Okay, you've successfully restarted your water heater. High five! But wouldn't it be even better if you could prevent it from conking out in the first place? Here are a few simple things you can do to keep your water heater happy and healthy:
- Flush the water heater regularly. This removes sediment that can build up in the tank and reduce its efficiency. Aim to flush your water heater at least once a year. There are videos online that walk you through this process. It's easier than you think!
- Check the anode rod. The anode rod is a sacrificial rod that protects the tank from corrosion. It should be replaced every few years, depending on the water quality in your area.
- Insulate the water heater. This can help to reduce heat loss and save energy. You can buy a water heater blanket at most hardware stores.
These simple steps can help to extend the life of your water heater and prevent costly repairs. Think of it as an investment in future hot showers (and who doesn't love hot showers?).
When to Call a Professional: Knowing Your Limits
Look, I'm all for DIY projects. But sometimes, you just have to call in the pros. Here are a few situations where it's best to leave the water heater repair to a qualified professional:

- You smell a strong gas odor. This is a serious safety hazard, and you should call your gas company or a qualified professional immediately.
- You're not comfortable working with gas or electricity. Safety first! Don't take risks if you're not confident in your abilities.
- You've tried everything and the water heater still isn't working. Sometimes, the problem is more complex than you can handle on your own.
- You're not sure what you're doing. It's always better to be safe than sorry. A qualified professional can diagnose the problem and fix it correctly.
There's no shame in admitting defeat. Calling a professional doesn't mean you're a failure. It means you're smart enough to know your limits and prioritize safety.
