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.
Tim was our service provider did an excellent job. We had a broken faucet that we couldn't get removed. He worked very hard and got the job done!! I was very happy with the quality service he provided.

"Very nice gentleman."
The Plumber that came out repaired what I needed but also pointed out the my shut off valve for the house was in very poor condition and recommended it be replaced. Since I am having new carpeting put down I would hate to see this happen so since he was here I had him repair that also. Very nice gentleman.

"All of his work was first rate and left the work area completely clean and ready for us to use"
Brad, our plumber, worked to figure out a way to make an existing plumbing setup work with a new application (sink and faucet). His diligence saved us several hundred dollars in not having to re-engineer drains. All of his work was first rate and left the work area completely clean and ready for us to use. Five Stars.

"Brad was very professional and quick."
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.
