What's included

Everything in every tankless water heater repair call

Error code diagnosis

We decode your unit's error display, run a full diagnostic and identify the root cause - not just the symptom the code is pointing to.

Component-level repair

We repair ignition systems, heat exchangers, flow sensors, gas valves, venting blockages and control boards - the full range of tankless failure points.

Descale if needed

Heavy mineral buildup is the most common cause of tankless inefficiency and failures. We descale the heat exchanger as part of the repair visit if scale is contributing to the problem.

Our water heater went out with a house full of kids and no hot water. Water Heater Rescue answered right away, came out the same day, explained everything clearly, and gave a flat price upfront. No hidden fees, no runaround. We had hot water again that afternoon.

FAQ

Common questions about tankless water heater repair

What does the error code on my tankless water heater mean?

Error codes vary by brand. Common codes indicate ignition failure, overheating, low flow, venting problems or sensor faults. We diagnose the specific cause - the code points us in the right direction but the real diagnosis happens on-site.

Is it worth repairing a tankless water heater?

Tankless units are built to last 20+ years, so repair is almost always worth it unless the heat exchanger has failed on an older unit. We'll give you an honest assessment of whether repair or replacement makes more sense for your specific unit.

My tankless heater worked fine until recently - what happened?

The most common sudden-onset issue is scale buildup on the heat exchanger, especially in hard water areas. Other common causes include a failing flow sensor, ignition component wear or a venting obstruction. We'll diagnose it on-site.

Do you carry parts for tankless water heaters?

We stock common parts for Navien, Rinnai and Rheem units. Less common parts may need to be ordered, but we'll tell you upfront if that's the case and give you an ETA.

Can you repair a tankless water heater that's still under manufacturer warranty?

Yes, but check your warranty terms first. Some warranties require service by a certified dealer. We are certified for several major brands - call us and we'll confirm coverage before scheduling.
