Fix Rinnai Error Code 11 - Replace Flame Rod Electrode (104000192‑K)

Rinnai Flame Rod Electrode Kit 104000192‑K (OEM Rinnai official part for all models) https://amzn.to/4bv6Nx6 The kit includes one fiber glass gasket/seal, two flame sensors, one flame ignitor rod. It takes less than 30 minutes for installation. The typical lifespan of the flame rod is between 8 and 15 years with 15 being on the top-end under best case conditions. In my case, approximately 3 mm of electrode material had been removed by electrical discharge erosion, which reduced both the intensity and consistency of the ignition spark. Cleaning the electrodes would not solve the problem.
