Navien Error Code E110 How To Fix

Okay, so your Navien is flashing E110 at you, like it's trying to send you a cryptic message. Don't panic! It's usually not a sign the house is about to explode (though it *feels* that way, right?).

Think of your Navien as a highly sophisticated water heater. This "E110" situation is often just a polite way of saying, "Hey, I'm not getting enough water, can you check that out?".

First things first: Unleash Your Inner Plumber!

Before you start imagining worst-case scenarios (like needing to re-plumb your entire house), let's check the obvious. We're talking super basic stuff, things your grandpa would probably tell you if he weren't busy napping.

1. The Mighty Faucet Test!

Go to the nearest faucet that *should* be getting hot water. Turn it on, full blast. Is the water pressure weaker than a kitten's sneeze?.

If it is, the problem might not be your Navien at all! It could be a wider plumbing issue affecting the entire house.

2. Valve Voyage!

Locate the water shut-off valves leading *to* your Navien. Are they fully open? Sometimes they get nudged or partially closed during other home projects (or by mischievous squirrels. Just kidding... mostly!).

Make sure those valves are wide open, like you're giving the water a VIP pass to the party.

3. Strainer Scrutiny!

Naviens, bless their digital hearts, often have a strainer or filter to catch debris. This little doohickey prevents gunk from gumming up the works. You might want to check this strainer is clean.

If it's clogged with more sediment than a riverbed, that could be your problem. Just clear away debris!

Still Stuck? Time to Troubleshoot Like a Pro! (Almost)

Alright, so you've checked the obvious and you're *still* staring down an E110. Don't worry, you've still got this!

4. Power Cycle Prowess!

Sometimes, all a Navien needs is a good old-fashioned reboot. Turn off the power to the unit at the breaker. Give it a solid five minutes to sulk, then turn it back on.

This is the equivalent of giving your Navien a digital pep talk. Maybe it'll cooperate this time!

5. The Pressure Puzzle!

Low water pressure to the unit will definitely trigger an E110 error. Check your water pressure regulator.

If your water pressure is too low it's probably the time to call a professional.

When to Call in the Cavalry (a.k.a. a Real Plumber)

Let's be honest, sometimes things are just beyond the scope of a weekend warrior. If you've tried all these steps and that pesky E110 is still glaring at you, it's time to call a professional.

You don't want to accidentally turn a simple fix into a plumbing catastrophe worthy of a sitcom episode.

A qualified plumber can diagnose more complex issues, such as a faulty flow sensor or a problem with the unit's internal components. These are definitely best left to the experts.

Remember, even attempting a few of these simple fixes can save you time and money when you *do* call the plumber. You'll be able to say, "I already checked X, Y, and Z," and sound incredibly savvy.

So, take a deep breath, grab your toolbox (and maybe a snack), and tackle that E110. You might be surprised at what you can accomplish!
