Frequently Asked Questions — Navien, Rinnai & Noritz Tankless Water Heater Error Code Repair & Descaling in Austin, TX ($195+)
Q: How do I fix Navien Error Code E003 or E012 in Austin?
Navien E003 and E012 indicate ignition or flame-sensing failure caused by carbon buildup on the flame rod, a closed gas valve, a scaled heat exchanger, or a clogged condensate trap. We clean the flame rod, verify gas manometer pressure, and descale the unit the same day. Call (737) 283-6243 for immediate assistance.
Q: What does Rinnai Code 11, Code 12, or LC mean on my tankless heater?
Rinnai Code 11 means no ignition, Code 12 means flame loss mid-cycle, and LC means ‘Lime Condition’ (Austin hard-water scale buildup restricting heat transfer). A $195-$265 professional descaling flush and flame-rod service clears the code and restores hot water. Call (737) 283-6243 for immediate assistance.
