Common Tankless Water Heater Problems We Fix

No Hot Water

Seems obvious, right? You probably didn't need us to tell you there's a problem if your house lacks hot water. But it's one of the most common issues we see! Whether it's a heating component issue, a gas supply hiccup, or something else, we know how to diagnose it fast. Our crew will make sure your tankless water heater is back to giving you those warm showers you've been missing.

Inconsistent Temperatures

One day it's scorching, the next it's freezing; can the water heater just make up its mind?! A tankless water heater should provide consistent temperatures, but when it doesn't, something's off. We'll figure out the problem, whether it's a sensor, a blockage, or something else, and get your hot water back in order.

Low Water Pressure

Ahh, one of the most annoying issues with your water heater. If it feels like you're getting nothing more than a dribble from your faucet, your tankless water heater might need some attention. Blockages, buildup, or even a valve problem could be the culprits. But don't worry—our team knows how to get your water pressure back to normal.

Weird Noises

Got a water heater that's making a racket and grumbling like it's dying for your notice? Tankless water heaters are usually pretty quiet, so if yours is making noise, it's time to call in the pros. Those odd sounds could mean anything from mineral buildup to a loose part, and ignoring them might lead to bigger issues.

Error Codes

This is how your system tells you it needs help. You might see error codes popping up on your tankless water heater, and even though they might seem mysterious, they're giving clues about the problem. These codes could point to issues like sensor malfunctions, low gas pressure, or even overheating. At Morris-Jenkins, we've seen every error code you can imagine, and we'll get your system back to supplying hot water in no time.

Giving Your System Some TLC

We get it; it's easy to adopt an "out of sight, out of mind" attitude toward your water heater. After all, if it's not broken, why bother? But here's the thing; maintenance isn't about fixing something that's working perfectly—it's about keeping your water heater running smoothly and avoiding bigger problems down the road.

Routine maintenance can help your tankless water heater perform better, last longer, and avoid those unexpected cold-water surprises. It involves making minor tweaks and adjustments, like flushing out mineral buildup, checking for wear and tear, and making sure all parts are working as they should.

At Morris-Jenkins, we make maintenance a breeze, so you can enjoy reliable hot water without worrying about sudden breakdowns. A little attention now can save you a lot of trouble later!

DIY Tricks to Fix Your Tankless Water Heater

At Morris-Jenkins, we've seen just about every situation with tankless water heaters. Even though they're built for reliability, they might still have the occasional glitch that throws off your routine.

The good news? Some issues have simple fixes you can try before calling for a service appointment. Knowing a few quick fixes in advance can save you time and get your hot water back faster the next time your system acts up!

When Is It Time To Call the Plumber?

Is the Gas Valve On?

You should be able to find the gas pipe that runs along the wall and into the heater. Somewhere on this pipe is the ON/OFF valve that controls the flow of natural gas. Feel comfortable to double-check that the valve is ON, but for safety reasons, don’t try any other work related to the gas line.

Does the Unit Have Electricity?

Another straightforward test you can do is making sure the unit is getting enough electricity. Check that the heater is plugged into a 120V outlet and the breaker hasn't tripped on your home's electrical panel. If you're often restoring power to the unit via the breaker box, definitely reach out to us for an examination.

Is the Exhaust Vent Blocked?

The exhaust vent is designed to make sure all harmful gases from the heater don't infiltrate your Waxhaw residence. If it's unable to perform its function, it signals the entire system to power off. You can inspect to see if there's an obstruction in the vent, but if there isn't, get in touch with Morris-Jenkins immediately.
