About Rinnai Code 11 Ignition Service

Rinnai on-demand water heaters display error code 11 when the unit attempts to ignite the burner but fails to establish a flame within the timing window. In Schaefferstown, Pennsylvania, closed gas valves, trapped air in gas lines, low dynamic gas pressure, or failed electronic igniters are the primary causes. Repeatedly power cycling the unit can wear down electronic ignition transformers. Our Rinnai service specialists measure inlet gas pressure under load, test spark electrode gaps, and inspect flame rod continuity. We eliminate error code 11 and restore dependable hot water for your entire home.

What Our Customers Say

Real reviews from homeowners and business owners we have helped.

Our Navien NPE-240A started beeping error code E003 on a freezing Tuesday morning. Marcus from TWH PRO's arrived within 40 minutes, tested the gas manifold pressure, cleaned the flame rod, and replaced a worn spark igniter on the spot. Having hot water back before our kids woke up was huge.

We went three days with lukewarm showers because our electric EcoSmart 27 kept tripping breakers. The technician tested the continuity of all three heating elements and found two had burned out from mineral scale. He swapped in genuine OEM canisters and descaled the chambers. Steaming showers are back.

Our restaurant dishwasher tripped a sanitation temperature alarm during Friday dinner service. TWH PRO's sent a commercial technician immediately. He cleared a clogged air intake screen on our cascaded Rinnai rack and re-calibrated the water servo in under an hour, saving our dinner service.
