Recirculation Pump Repair in Old Orchard Beach
Many tankless systems use internal or external recirculation to deliver hot water faster. Pump failures, check valve problems or wrong schedule settings can cause long waits or lukewarm water. We test the pump, check valves and controls and set the schedule to match your routine. A properly tuned system saves both water and gas.

Pilot Light and Ignition Repair in Old Orchard Beach, ME
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Old Orchard Beach, ME diagnoses issues with igniters, flame sensors and gas valves. We confirm proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents hazardous gas problems and restores your unit's ability to heat water on demand.
Ignition Failure Repair in Old Orchard Beach, ME
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Rinnai Tankless Water Heater Repair in Old Orchard Beach, ME
Rinnai is a popular tankless brand, and its units can face challenges such as scaling from hard water or issues with their flame rod. Our technicians in Old Orchard Beach, ME are adept at Rinnai tankless water heater repair, focusing on descaling services, fan motor replacements and resolving issues with gas valve assemblies. We ensure your Rinnai system continues to provide reliable, on-demand hot water, following manufacturer specifications.
Condensing Tankless Repair in Old Orchard Beach, ME
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and verify proper drainage. PVC venting is also checked for slope and sagging.
Tankless Descaling and Flushing in Old Orchard Beach
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is a smart move for most homes on hard water.
Tankless Repair vs Replacement Cost in Old Orchard Beach, ME
Descaling service typically costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed typically ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

Navien Tankless Water Heater Repair in Old Orchard Beach
Navien units are known for their advanced condensing technology but can sometimes develop issues with their circulation pump or exhaust systems. BKN Plumbing provides specialized Navien tankless water heater repair in Old Orchard Beach, addressing common problems like ignition failures or condensate drain blockages.

Frequently Asked Questions About Tankless Water Heater Repair in Old Orchard Beach
The cost of tankless water heater repair in Old Orchard Beach, ME can range from $150 to $800 or more, depending on the issue. Simple fixes like sensor replacements might be at the lower end, while major component replacements like a heat exchanger could be higher. We provide a detailed estimate after diagnosis.
Common causes of failure include mineral buildup from hard water, ignition problems, faulty flow sensors, clogged air filters, exhaust venting issues and electrical component failures. Regular maintenance, including descaling, can prevent many of these problems.
Minor tankless water heater repairs, such as replacing a sensor or igniter, typically do not require a permit in Old Orchard Beach. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to ensure code compliance.
This often comes from low gas pressure, a blocked intake or exhaust, a dirty flame rod or overheating from scale. We test each possibility to find the cause.
While some basic maintenance like filter cleaning can be done by homeowners, complex repairs involving gas lines, high voltage electricity or delicate internal components should always be left to a licensed professional. DIY attempts can be dangerous and void warranties.
Typical signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms warrant a professional inspection.
Yes, our technicians are trained and experienced in repairing all major tankless water heater brands, including Rinnai, Navien, Noritz, Rheem, Bosch, A.O. Smith and more. We carry a wide range of common parts for various models.
Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a professional.
