About Rheem Code 13 Combustion Fix

Rheem error code 13 indicates improper combustion, poor flame stability, or abnormal exhaust ventilation during operation. In Cornwall, Pennsylvania, dirty blower fan impellers, blocked air intake screens, or excessive flue backpressure cause the flame to burn lean or rich. When the flame rectification current drops below safe operational thresholds, the control board trips code 13 to prevent carbon soot buildup inside the copper heat exchanger. Our technicians clean combustion blower assemblies, inspect exhaust flue runs, and check flame current with digital multimeters. We restore clean, balanced combustion and clear code 13.

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.
