Common Signs Your Tankless Water Heater Needs Repair
Tankless water heaters generally require fewer repairs than tank units, which is exactly why it matters to address issues promptly when they do appear. These are the signs our technicians see most.
No Hot Water
A clear indication of a problem is the absence of hot water throughout your home.
Unit Shutting Off
If your tankless unit turns off unexpectedly, it may indicate a clog or a more complex issue.
Leaks
Although less common on tankless units, leaks can occur at loose valves or fittings and need prompt attention.
Appliances Not Functioning
If your dishwasher or washing machine is misbehaving, the issue may stem from the tankless unit feeding them.
Unusual Water Quality
Strange colors or tastes in your hot water signal a problem that requires professional assessment.
Inconsistent Temperature
Significant fluctuations in water temperature point to a fault in the flow sensor, heat exchanger, or controls.

3 months agoThomas was professional and went a step above. Did a great job to show me everything that I had to keep an eye on and cleaned up like he wasn’t never there. Price wise I’m on their membership program we bought with our new system. They’ve been good so far and it’s been a few yrs now.
Michelle Mullins
4 months agoShowed up on time. Respectful, kind, and efficient. I’m sure my husband could have replaced the capacitor but for the price and convenience we were happy to spend our money here. They installed our furnace last year and we have always happy with CJS.
Richard Wirey

A Wal
5 months agoWe had an issue with our sump pump going off, even though there wasn’t any water problem, and it turned out the entire unit needed to be replaced. We called Bassett that morning, and they were able to offer same-day service, which we really appreciated. Throughout the day, I received texts and calls keeping me updated that they were still coming, even as other jobs ran longer. I didn’t mind the delay at all—it was clear they were doing their best to fit us in. Josh arrived later in the day and spent a few hours replacing the sump pump. He explained everything clearly and was both informative and understanding throughout the process. He also took the time to look at another issue, took photos and measurements, and said he would follow up after speaking with his boss. What really stood out was his professionalism and attitude. Even after 6 p.m., when he mentioned he still had two more stops to go, he never once rushed or made us feel like just another job. He made us feel like a priority, and that meant a lot. We’re very grateful for the service and would absolutely recommend Bassett, and especially Josh, to others.
Michelle McElwee
7 months agoWe got estimates for a new water softener. I hadn't compared prices anywhere else. After receiving your estimate I called another service. To install and replace it was 5 and 6000 dollars less. Wow what a difference. We are going with the other service. Dale was great. He was very helpful. And so nice. The gal on the phone was also nice. Overall great experience. It just a money thing. Thank you so much Have a nice spring, Michelle

FAQ
Tankless Water Heater Repair FAQ
What are the Most Common Reasons for Tankless Water Heater Repairs?
Do Tankless Water Heaters Have Parts That Need Regular Replacement?
When it comes to hot water heating equipment, the “tankless” design offers some serious advantages over traditional tank models. With no large reservoir to constantly keep heated, these modern marvels only fire up on demand to heat water as you need it. Energy efficiency, space savings, endless hot water – what’s not to love? But just because they don’t have an integrated tank doesn’t mean tankless water heaters are completely maintenance-free. While they may be lower maintenance overall, some components still require periodic replacement to keep your system operating safely and at peak performance.
Normal Noises vs Problematic Noises in Tankless Water Heaters
A little background noise from your tankless water heater is totally normal. The Sounds of Endless Comfort: Fan Whirring (an integrated fan circulates air for combustion, creating a low whirring hum), Ignition Clicks (a brief clicking sound as the igniter engages every heating cycle), Expansion Pops (thermal expansion can cause pinging or popping noises), and Water Flow Noises (the actual flow of water entering and exiting the unit). These ambient noises are no cause for concern. When Noises Signal Trouble: Screeching Fan (may have an obstruction or bearing issue), Booming Ignition (could signal gas flow problems or ignitor faults), Intense Clanging (likely means the heat exchanger has overheated and warped), Rumbling or Knocking (red flags that mineral scaling buildup is obstructing water flow paths), and Hissing or Whistling (air leaks within the sealed combustion chamber that require sealing). If you notice any of these disruptive or unusual sounds, have one of Bassett’s plumbers fully diagnose the issue before minor noises turn into major hot water headaches.
Are There Any Shock Risks With Older Tankless Water Heaters?
While tankless water heaters are renowned for their efficiency and safety compared to traditional tank models, that doesn’t mean they’re completely free of potential hazards as they age. Even the most well-built systems won’t last forever. And when it comes to any appliance combining water and electricity, older units require some extra precautions.
Can a Power Surge Damage My Tankless Water Heater?
These days, it seems like every appliance and electronic device in our homes is vulnerable to power surges and electrical spikes. The digital age has brought incredible conveniences, but also some added risks when voltage levels fluctuate unexpectedly. Your trusty tankless water heater is no exception when it comes to potential surge damage. While they may seem simple on the outside, today’s tankless models pack a surprising amount of sensitive electronic controls under the hood. Circuit boards precisely regulate temperatures, monitor operations, and control the ignition sequences that fire up the burners. Even a minor power surge can potentially fry these intricate components.
Cost Considerations for Tankless Water Heater Repair
The cost of fixing a misbehaving tankless water heater varies pretty widely depending on the specific issue. The “Easy Button” Repairs (lower end): replacing worn-out igniters, recalibrating or swapping faulty thermostats, repairing electrical issues with control boards or wiring, and clearing obstructions and repairing venting. The Bigger Ticket Repairs: replacing the main heat exchanger component, performing chemical flushing services to clear mineral buildup, and repairing issues with gas feed lines or control valves. Factors That Increase Costs: Age/Condition of the Unit, Quality of Parts Used, Accessibility Issues (tight installation spaces increase labor time), and Home Construction Type (safe access through drywall, crawlspaces, or finished areas adds complexity). The Replacement Route: in some cases, repairing an aging tankless system can approach the price of full replacement, which offers maximum efficiency, full warranty coverage, and longevity. Bassett provides straightforward explanations and advice on all factors impacting costs.
How to Avoid Costly Tankless Water Heater Repairs?
A little preventative maintenance for your tankless water heater goes a long way toward avoiding nasty surprises and expensive repairs down the road. Put Mineral Buildup in Check: if you have hard water, an annual deliming flush service keeps mineral buildup to a minimum. Bassett’s plumbers use specialized descaling solutions. Maintain Ideal Water Conditions: adding filtration helps remove contaminants, and installing a water softener virtually eliminates mineral buildup struggles; also have pH levels checked annually, since acidic or basic conditions rapidly corrode heat exchangers, plumbing lines, and fittings. Don’t Skip Annual Tune-Ups: Bassett’s comprehensive multi-point inspection tests airflow and venting performance, cleans fans and critical components, checks electrical connections and controls, verifies safety mechanisms, and monitors for signs of deterioration. A little routine care and professional preventative maintenance truly goes a long way toward maximizing your investment.
