Pilot Light & Ignition Repair in Brockton, MA
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production. Our team in Brockton, MA 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 dangerous gas problems and restores your unit's ability to heat water on demand.

No Hot Water Tankless Repair in Brockton
When your tankless unit fails to produce hot water, it is often due to issues with the ignition, gas supply or a clogged heat exchanger. Our technicians in Brockton will thoroughly diagnose the root cause, whether it is a faulty igniter, a pressure sensor fault or mineral buildup. We carry common replacement parts for quick fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is crucial for the safe operation of your unit.
Condensing Tankless Repair in Brockton, MA
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 inspected for slope and sagging.
Tankless Repair vs Replacement Cost in Brockton, MA
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.
Flow Sensor and Thermistor Repair in Brockton
Tankless heaters rely on flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace failed parts. Temperature becomes steady again once readings are accurate.
Emergency Tankless Water Heater Repair in Brockton, MA
A sudden loss of hot water can be an emergency, especially on a cold morning in Brockton, MA. BWM Plumbing offers emergency tankless water heater repair to address serious failures promptly. We are available to troubleshoot issues like major leaks, complete system shutdowns or repeat error codes that prevent any hot water production. Our fast response team works quickly to restore your hot water, often on the same day.
Tankless Water Heater Descaling Service in Brockton
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Pinhole leaks in older copper lines are a familiar problem where the water is aggressive, and they tend to show up in clusters. Our descaling service in Brockton involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.

Tankless Water Heater Error Code Diagnostics in Brockton, MA
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in Brockton, MA are trained to interpret these codes accurately, using specialized diagnostic tools to pinpoint the exact component failure.

Frequently Asked Questions About Tankless Water Heater Repair in Brockton
Most tankless repairs cost between $175 and $600, depending on the part. Descaling service often runs $175 to $350, while heat exchanger replacement can exceed $800 if not under warranty. We quote before any work begins.
Many tankless heat exchangers carry long warranties, while other parts usually have shorter coverage. Warranties may require proof of maintenance, which we document.
Common 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.
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 pro.
Minor repairs usually do not require a permit. If the repair involves major changes to the gas or water lines, or if the unit itself is being replaced, a permit from the Brockton building department may be necessary. We handle all required permitting for you.
Minor tankless water heater repairs, such as replacing a sensor or igniter, usually do not require a permit in Brockton. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to ensure code compliance.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still wise.
Regular maintenance, particularly annual descaling, is crucial for tankless water heaters in homes with hard water. It prevents mineral buildup, maintains efficiency, extends the lifespan of the unit and helps avoid costly repairs by catching small issues before they grow.
