Most tankless repairs cost between $175 and $600, depending on the part. Descaling service often runs $175 to $350, while heat exchanger replacement can exceed $800 if not under warranty. We quote before starting.
Error codes can be caused by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code points to a specific system malfunction.
Typical signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms call for a professional inspection.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require special tools and knowledge. Attempting DIY repairs on gas or electrical components can be dangerous and void your warranty. It is always best to call a professional.
Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a professional.
