Error codes indicate specific failure points. Common causes include low gas pressure, ignition failure, scale buildup on the heat exchanger, or flow sensor malfunction. We diagnose the exact cause.
This can result from a failed igniter, gas supply issue, flow sensor problem, or heat exchanger failure. A proper diagnostic is needed to identify the specific cause.
Annual maintenance including descaling is recommended for most Douglas County water conditions to prevent scale buildup and maintain efficiency.
Tankless units are built to last 20 or more years. If the unit is under 15 years old, repair is usually cost-effective unless the heat exchanger has failed.
