About Rheem Code 11 Ignition Repair

Rheem on-demand water heaters display error code 11 when the control board fails to verify burner ignition during startup. In Cornwall, Pennsylvania, closed gas isolation valves, dead ignition electrodes, corroded wiring plugs, or low static gas line pressure will trigger this error. Resetting the unit repeatedly only stresses electrical components and risks delayed ignition pops. Our Rheem repair specialists test high-voltage spark intensity, verify gas supply pressures under load, and inspect electrical continuity across the primary circuit board. We resolve error code 11 quickly so you never have to endure cold water outages.

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.
