Reset Navien Tankless Water Heater

Okay, so your Navien tankless water heater is acting up, huh? Don't worry, it happens! It’s not the end of the world (unless, of course, you really love your scalding hot showers – then maybe it's a tiny bit catastrophic). But seriously, before you call a plumber and empty your wallet, let's try the old faithful reset. It's like a digital detox for your water heater. Ready?

Think of it this way: sometimes our brains just need a reboot, right? We get stressed, forget where we put our keys (which, by the way, where are my keys?), and generally act a little…off. Tankless water heaters are kind of the same. They have all these fancy sensors and circuits, and occasionally they just need a little nudge to get back on track.

Why Reset a Navien Tankless Water Heater?

So, why might your Navien be throwing a tantrum and deserving of a reset? Well, there are a few usual suspects. Let's play detective, shall we?

• Error Codes Galore: Is your display screen lit up like a Christmas tree with error codes? Codes like E012, E020, E151? Yeah, those are Navien's way of saying, "Houston, we have a problem!" A reset can often clear these temporary hiccups. Sometimes, it's just a sensor being a drama queen.


• Cold Shower Blues: Nobody likes a surprise cold shower! If your hot water is playing hide-and-seek, a reset can sometimes coax it back into action. Just imagine shivering, reaching for the shampoo, and then BAM! Ice bath. No fun.


• Inconsistent Temperatures: Is your water going from scalding hot to lukewarm faster than you can say "Goldilocks"? That's annoying, isn't it? Again, a reset might be the answer. Might. No guarantees in life, folks, except death and taxes (and maybe that one friend who's always late).


• No Hot Water at All: The ultimate betrayal! If your Navien is completely ghosting you on the hot water front, a reset is definitely worth a try before calling in the professionals. Think of it as the Hail Mary pass of water heater repair.


• After a Power Outage: Sometimes, a power surge or outage can scramble the brains of your water heater. A reset can help it remember what it's supposed to do (namely, provide you with gloriously hot water!).

The (Relatively) Easy Reset Process

Alright, enough chit-chat! Let's get down to the nitty-gritty. Resetting a Navien tankless water heater is usually pretty straightforward. But, and this is a big but, always refer to your owner's manual. I know, manuals are boring, but they're your best friend in these situations. They'll have specific instructions for your model. Trust me, you don't want to accidentally turn your water heater into a paperweight.

Method 1: The Power Cycle (aka The "Have You Tried Turning It Off and On Again?" Method)

This is the classic, the tried-and-true, the "if all else fails" approach. It’s also usually the first thing tech support will ask you to do, so why not get ahead of the game?

1. Locate the Power Switch: Find the main power switch for your Navien unit. It's usually near the unit itself, sometimes behind a panel. Don't go poking around blindly! Safety first, kids.


2. Flip the Switch: Turn the power switch to the "OFF" position. And I mean completely off. Don't be wishy-washy about it.


3. Wait a Few Minutes: This is the crucial part! You need to give the system time to fully discharge. Think of it as letting it take a deep breath. I usually recommend waiting at least 5 minutes, but 10 is even better. Go grab a coffee, do a quick yoga pose, contemplate the meaning of life – whatever floats your boat.


4. Flip the Switch Back On: After your designated waiting period, flip the power switch back to the "ON" position.


5. Cross Your Fingers: Now, wait a few minutes for the unit to power up and go through its self-check. Keep an eye on the display screen. Hopefully, those pesky error codes are gone!

Did it work? Awesome! You're a water heater whisperer! If not, don't despair. We have other tricks up our sleeves.

Method 2: The Control Panel Reset (aka The "Button Mashing" Method)

Some Navien models have a dedicated reset button on the control panel. This is usually a little more direct than the power cycle method. Again, consult your manual for the exact location and procedure, but here's the general idea:

1. Find the Reset Button: Scour your control panel for a button labeled "Reset" or something similar. It might be hidden behind a small door or cover. These things are designed to be aesthetically pleasing AND functional, you know?


2. Press and Hold: Once you've located the reset button, press and hold it for a few seconds. Usually, 5-10 seconds will do the trick. You might hear a beep or see a light flash.


3. Release and Observe: Release the button and watch the display screen. The unit should go through a reset sequence. Again, keep an eye out for error codes.

Still no luck? Okay, don’t panic. We're not giving up yet. But maybe it's time to consider... (dun dun DUUUUN!)… the manual.

Method 3: The Manual (aka The "When All Else Fails, Read the Instructions" Method)

Seriously, I know it's tempting to just keep randomly pushing buttons, but your owner's manual is a treasure trove of information. It will have specific reset instructions for your exact model, including any model specific codes that might need addressing. I understand, reading manuals is like watching paint dry, but sometimes it's necessary. Plus, you might even learn something new! Like, did you know your Navien can also… okay, never mind. Just read the manual.

When to Call a Professional

Okay, so you've tried everything, and your Navien is still stubbornly refusing to cooperate. At what point do you throw in the towel and call in the big guns? Here are a few signs that it's time to admit defeat and call a qualified plumber:

• Persistent Error Codes: If the same error codes keep popping up, even after multiple resets, it indicates a deeper underlying problem.


• Strange Noises: Is your water heater making weird gurgling, banging, or hissing sounds? That's not a good sign. It could indicate a problem with the heat exchanger or other internal components.


• Gas Leaks: If you suspect a gas leak, get out of the house immediately and call your gas company or 911! This is not a DIY situation. Seriously. Gas leaks are dangerous.


• You're Uncomfortable Working with Plumbing/Electricity: Let's be honest, some things are best left to the professionals. If you're not comfortable working with water pipes or electrical wiring, don't risk it. It's better to pay a plumber than to accidentally flood your house or electrocute yourself.


• Your Gut Feeling: Sometimes, you just have a feeling that something's seriously wrong. Trust your instincts. If you're uneasy about anything, call a professional.

Remember, a qualified plumber can diagnose the problem accurately and perform the necessary repairs safely and efficiently. It's an investment in your peace of mind (and your hot showers!).

Preventative Maintenance: Keeping Your Navien Happy

The best way to avoid water heater woes is to keep your Navien properly maintained. Think of it like taking care of your car. Regular maintenance can prevent costly repairs down the road.

• Regular Flushing: Tankless water heaters can accumulate mineral deposits over time, which can reduce their efficiency and lifespan. Flushing the unit regularly (usually once a year) helps to remove these deposits. Your manual will have instructions on how to do this, or you can hire a plumber to do it for you.


• Inspect the Venting: Make sure the venting is clear of obstructions. Birds, squirrels, and other critters love to build nests in vents, which can cause dangerous carbon monoxide buildup.


• Check the Water Pressure: High water pressure can damage your water heater and other plumbing fixtures. Consider installing a pressure regulator to keep your water pressure within a safe range.


• Consider a Water Softener: If you have hard water, a water softener can help to prevent mineral buildup in your water heater and other appliances.


• Schedule Regular Maintenance: Consider scheduling regular maintenance with a qualified plumber. They can inspect your water heater, identify potential problems, and perform preventative maintenance to keep it running smoothly.

So, there you have it! Everything you need to know (and probably more!) about resetting your Navien tankless water heater. Hopefully, this guide has helped you get your hot water back on track. And remember, if all else fails, call a professional. They're there to help! Now go enjoy that hot shower… you've earned it!
