Frequently Asked Questions

Why Is My Tankless Water Heater Displaying an Error Code, and What Should I Do First?

Error codes are the unit's way of communicating a specific problem it has detected, often relating to ignition failure, flow issues, or overheating. The code is usually tied to a sensor reading that indicates a component is failing or operating outside of its parameters. Your immediate first step should be to consult your unit's owner's manual to identify the specific meaning of that code. If a simple fix, such as clearing a clogged air intake or resetting the unit, does not resolve the issue, you should call a professional technician.

Can I Repair My Tankless Water Heater on My Own?

While simple maintenance tasks, such as cleaning the intake screen or resetting the unit, can often be performed by a homeowner, major repairs should generally be left to licensed professionals. Tankless water heaters involve complex gas lines, high-voltage electricity, and sensitive electronic components, which pose significant safety risks. Attempting to repair internal components without proper certification can void your warranty and potentially lead to further damage or dangerous situations. For safety and compliance, always contact a trained technician for any complex diagnosis or repair.

Is the Cost of Repairing My Tankless Water Heater Worth It, or Should I Consider Replacement?

The decision to repair or replace often comes down to the age of the unit, the extent of the damage, and the overall cost of the repair. If your tankless water heater is less than halfway through its expected lifespan of 15 to 20 years and the repair cost is low, fixing it is typically the more economical choice. However, if the unit is older, has suffered significant damage due to lack of maintenance, or if the repair cost exceeds 50% of a new unit's price, replacement might be the smarter long-term investment. A professional technician can provide an honest assessment of your unit's condition, helping you make the best decision.

How Long Does a Typical Tankless Water Heater Repair Appointment Take?

The duration of a tankless water heater repair appointment largely depends on the complexity of the underlying issue that the technician needs to address. Simple tasks, such as replacing a minor sensor or flame rod, or performing a flush, may only take an hour or two to complete. However, if the issue involves diagnosing a tricky electrical short or replacing a main heat exchanger, the repair could take significantly longer. Experienced technicians arrive with common parts stocked to ensure they can complete most repairs efficiently on the first visit.

How Often Should I Have My Tankless Water Heater Flushed to Prevent Problems?

A professional descaling flush is the most important maintenance task for a tankless water heater, as it removes the mineral buildup that significantly reduces efficiency and lifespan. For most homes, especially those in areas with moderately hard water, such as Poughkeepsie, this procedure should be performed annually to prevent component failure. If your home has extremely hard water or very high water usage, you might need to schedule a flush every six to nine months. Consistent flushing is crucial because scale buildup is the leading cause of poor performance and costly repairs for all tankless units.
