| Component | Common Fault | Our Approach |
|---|---|---|
| Igniter / Flame Rod | Spark not generating or flame not sensed — E003/11 lockout | Test spark gap and flame rectification signal; clean or replace |
| Gas Valve / Modulating Valve | Not opening, not modulating, or stuck | Test solenoid voltage and flow; replace if failed |
| Heat Exchanger | Scale build-up reducing flow and heat transfer; pinhole leak | Descaling flush (annual maintenance) or replacement if cracked |
| Flow Sensor | Unit not activating at normal flow rates | Test flow sensor output and clean or replace |
| Inlet/Outlet Temp Sensors | Incorrect temperature readings — erratic water temperature | Test thermistor resistance vs temperature curve; replace if failed |
| Fan/Venting | Blocked exhaust or intake — E030 or no ignition | Inspect and clear vent path; test fan operation and motor |
| Condensate System | Blocked neutraliser or drain — E351 or lockout | Clear condensate line, replace neutraliser media if exhausted |
| Control Board | Random lockouts, incorrect error codes, communication fault | Diagnose via error history and component test; replace board if required |
Write down any error codes shown on the unit display. Note whether you have no hot water at all, or intermittent issues. This information helps us arrive prepared.
Our Red Seal technician arrives with brand-specific diagnostic tools and common replacement parts for Navien, Rinnai, and Rheem tankless units.
We test gas pressure, ignition, flow sensor, temperature sensors, and heat exchanger condition to find the root cause — not just clear the code.

"After 12 years of having James maintain, repair and install anything required for our gas, heating and plumbing needs, I continue to highly recommend him. Professional, incredibly thorough, educates us every step."
"I can't recommend James enough. He took on an extremely difficult job with our home's heating system. Most other plumbers flat out refused the job. James turned a nightmare scenario into a perfectly functioning system."
