When To Call for Tankless Water Heater Repair
Tankless units are built for efficiency and convenience, but they can still develop problems—especially as they age or if mineral buildup starts to restrict performance. If you’re noticing any of the warning signs below, it’s time to schedule Tankless Water Heater Repair in Woburn, MA with our team.
Common signs something’s wrong include:
- No hot water (or not enough hot water)
- Hot water turning cold mid-use
- Visible leaks or moisture around the unit
- Odd sounds are coming from the system
- Error codes or intermittent operation
- Pilot/ignition-related issues (for gas units)
On our Woburn tankless page, we also call out familiar homeowner complaints like leakage, odd sounds, plumbing troubles, pilot light issues, and water temperature shifting unexpectedly—issues that can point to wiring/circuit concerns or other system faults.
Tankless Water Heater Not Producing Hot Water
When there’s no hot water (or it’s lukewarm), the cause is often something simple—but not always something you should guess at. Tankless systems rely on sensors, safe ignition, correct venting, and proper flow rate to heat water on demand.
A few common causes we see:
- Restricted flow due to a clogged inlet filter or buildup
- Ignition or burner problems (gas units)
- Faulty sensors or controls
- Temperature settings that were changed or reset
- Venting/exhaust issues that trigger shutdowns
The fastest way to stop the frustration is a proper diagnostic visit, so you’re not paying for “trial and error.”
Tankless Water Heater Error Codes and What They Mean
Seeing an error code is your tankless unit’s way of telling you it detected a condition that isn’t safe or isn’t working correctly. Depending on the brand and model, codes can point to:
- Air intake or exhaust/vent blockages
- Flame/ignition failure
- Overheating protection events
- Sensor malfunctions
- Circuit board or wiring concerns
Because codes can vary by manufacturer, we don’t recommend searchingfor a code and guessing. We’ll read the code, confirm what’s happening in the system, and fix the underlying issue—not just clear the display.
Hard Water Scale Buildup and Descaling Service
In Massachusetts homes, mineral buildup can be a real issue for tankless performance. Over time, scale can reduce efficiency, cause inconsistent temperatures, and increase wear on key components.
When buildup is part of the problem, we may recommend tankless descaling/flushing as part of your repair plan. This helps restore performance and can reduce the chance of repeated breakdowns.
Signs of mineral buildup may be involved:
- Hot water fluctuates or takes longer than usual
- The unit seems to “struggle” during higher demand
- Efficiency drops, and the system works harder than it should
- You’re seeing repeat service issues over a short period
If you’re not sure whether your tankless system has ever been flushed, we can help you set a practical maintenance plan.
Gas Tankless Water Heater Repair vs. Electric Tankless Repair
Tankless problems don’t look the same across gas and electric systems. The good news: we service both and tailor the repair to the equipment in your home.
Gas Tankless Water Heater Repair
Gas units can develop issues with:
- Ignition or flame sensing
- Combustion air / venting problems
- Gas supply or pressure-related faults
- Condensate drainage (on condensing models)
Electric Tankless Water Heater Repair
Electric units may experience:
- Heating element wear
- Power supply or breaker issues
- Sensor or control board problems
- Flow-sensing faults that prevent activation
Either way, the goal is the same: safe operation, stable temperature, and reliable hot water when you need it.
Navien Tankless Water Heater Repair in Woburn
Many homeowners ask us about Navien specifically—and for good reason. We regularly discuss and service Navien tankless water heaters, and our site notes Navien as a leader in high-efficiency water heaters with space-saving benefits and strong energy efficiency.
If you have a Navien unit in Woburn and you’re dealing with performance issues, we can help you troubleshoot, repair, and restore dependable hot water—while also advising you when a repair makes sense versus when replacement is the smarter long-term call.
Repair vs. Replacement: How to Know Which You Need
One of the most common concerns we hear is: “Should I repair it, or is it time to replace it?”
We take a practical approach. If a repair will restore reliable performance and make financial sense, we’ll tell you. If your unit is older and facing repeated failures, we’ll walk you through replacement options.
Our Woburn tankless page notes that tankless water heaters often remain in good working order for about 10–15 years, and units older than that can run into more frequent trouble.
Replacement may be worth considering when:
- The unit is near or past its typical service life
- Repairs are becoming frequent
- Performance issues keep returning
- The cost of repair is approaching the value of upgrading
We’ll explain your options clearly, with upfront pricing—so you can make the decision that’s best for your home and budget.

People Also Ask: Tankless Water Heater Repair Questions
This can happen when the unit is struggling with flow rate, mineral buildup, sensors, or an ignition/combustion interruption (gas units). It’s also a symptom we flag on our Woburn tankless page, and it can sometimes point to circuits or wiring concerns.
Often, yes—especially if the unit isn’t near the end of its life and the issue is isolated. If the unit is older (commonly 10–15 years of solid service, sometimes more with maintenance) and repairs are stacking up, replacement may be the better investment.
Many repairs can be completed the same day, especially when the technician can diagnose quickly and has the right parts available. We also stock our trucks to help finish many repairs in a single visit.
The most common issues include no hot water, error codes, leaks, temperature fluctuations, and performance loss due to mineral buildup.
Yes. Regular service helps maintain efficiency, reduce scale buildup risk, and prevent inconvenient breakdowns—especially in areas where mineral content can affect plumbing equipment over time.
