Signs Your Tankless Water Heater Needs Repair
Tankless units are generally reliable, but they do fail. These are the signs it’s time to call a technician rather than wait:
No hot water or a sudden loss of hot water mid-use
Inconsistent or fluctuating water temperature
Error or fault codes on the unit’s control panel
Banging, rumbling, or hissing sounds during operation
Visible water leaks around the unit or its connections
Reduced hot water pressure at fixtures throughout the home
The unit fires but shuts off before water reaches temperature
Any of these symptoms can signal a problem that gets worse the longer it sits. Catching an issue early typically means a simpler, less costly repair.

Knowing what’s behind your symptoms helps you have a more informed conversation with your technician. In the Fox Valley, one driver stands out above the rest: hard water.
Parts of the Fox Valley and Kane County area have naturally elevated mineral content in the water supply. Over time, those minerals deposit as scale inside the unit’s heat exchanger, restricting water flow and reducing heating efficiency. Left untreated, scale buildup is one of the leading causes of premature tankless water heater failure in this region. Annual descaling can significantly reduce the likelihood of an unplanned repair call.
Most modern tankless units display numeric or alphanumeric error codes when something goes wrong. Those codes give a trained technician a clear starting point, which can mean faster diagnostics and less time without hot water.
Other frequent repair causes include:
Flow sensor malfunction: the unit can’t detect water movement, so it won’t trigger the burner
Ignition or flame failure: the unit attempts to fire but can’t sustain a flame
Heat exchanger damage: often the result of prolonged scale accumulation or overheating
Venting obstructions: blockages that activate safety shutoffs and halt operation
Repair or Replace? How to Decide
Tankless water heaters typically last 15 to 20 years with proper maintenance, considerably longer than conventional tank-style units. Whether repair or replacement makes more sense depends on where your unit falls in that lifespan and what it’s been through.
A unit under 10 years old experiencing its first significant problem is usually a strong candidate for repair. A unit approaching or past the 15-year mark, one that has needed repeated repairs in a short window, or one driving noticeably higher energy bills may be telling you replacement is the better investment. Our technicians review error history, inspect the heat exchanger and key components, and give you a clear recommendation based on the unit’s actual condition.
If replacement turns out to be the right path, financing options are available to make that decision easier. And if repair is the answer, our Amy Club Membership program provides ongoing maintenance support to help extend the life of your system after the fix.
We needed our kitchen faucet replaced and I called Amy's, they came within ten minutes. Brad was very professional and quick. I will definitely use them in the future for our plumbing needs.

"Tim was very good at telling us what the problem was, how he would fix it and how to prevent this in the future"
Tim was very good at telling us what the problem was, how he would fix it and how to prevent this in the future. He installed a new outside faucet and explained how to shut off the water flow in the fall to prevent water from entering the faucet and freezing.

"It's very easy to be a Club member year after year when the service is this good."
I am writing to rave about the work that Scott and Ae did in tandem to install our new AC and meter box. As always with Amy, the detail work was meticulous. If you need work done, Scott is the best - personable, thorough, and really breaks down what is critical and what is an unnecessary expense at the time. Ae's work on the condenser box for the AC was so clean you would have never known that it was a replacement! It's very easy to be a Club member year after year when the service is this good.
