• Water Discoloration or Smell: Rusty or sulfur-like odor indicating internal corrosion or bacterial buildup.

Common Tankless Water Heater Issues

Scaling and Mineral Buildup

Hard water minerals collect on the heat exchanger, reducing efficiency and causing overheating shutdowns.

Ignition and Burner Malfunctions

Faulty igniters, flame rod corrosion or clogged burners can prevent ignition or cause incomplete combustion.

Sensor and Control Board Faults

Damaged flow sensors, temperature probes or circuit boards may trigger error codes and erratic operation.

Low Water Flow and Pressure Problems

Partially closed valves, clogged inlet filters or pressure relief valves can restrict proper water delivery.

Leak Detection and Valve Failures

Cracked fittings, worn seals or failed relief and isolation valves risk water damage and safety shutdowns.

Our Repair Process

On-Site Diagnostic and Safety Inspection

We begin with a complete system evaluation—assessing the heat exchanger, burner assembly, venting, water connections and electrical controls. Each component is tested under real-world demand to pinpoint the root cause.

Detailed Estimate and Options Review

Following inspection, you receive an itemized estimate outlining recommended repairs, genuine manufacturer parts and labor requirements. If replacement is more cost-effective than repair, we’ll explain the trade-off.

Precision Repair and Parts Installation

Certified technicians execute repairs using factory-authorized replacement components. Common services include heat exchanger descaling, sensor recalibration, burner cleaning, valve replacement and electronic control board swaps.

Performance Testing and Calibration

Upon repair completion, we run your tankless system through a full load test—verifying temperature accuracy, flow rate, ignition reliability and safety controls. Adjustments are made to factory-specified settings.

Cleanup and Final Review

Our team leaves your work area spotless, removing all packaging and debris. Before departure, we review the completed work, answer questions and offer proactive care recommendations.

Maintenance and Prevention

Routine maintenance is the best defense against sudden water heater failure. Annual or biannual tune-ups include:

• Descaling and Flushing: Eliminate mineral deposits inside heat exchangers to preserve efficiency.
• Filter and Screen Cleaning: Remove sediment from inlet filters and secondary water screens.
• Burner and Vent Inspection: Ensure proper combustion and clear vent paths.
• Safety Valve Testing: Confirm pressure relief and temperature safeguards function correctly.
• Control Calibration: Verify sensor accuracy and adjust temperature settings.

Regular maintenance not only extends the life of your tankless heater but also maintains energy efficiency and reduces the likelihood of emergency calls.
