When people phone about tankless water heater repair in Bainbridge Island, WA, it is nearly always one of these problems. Each has a short list of causes.

Unit won't light
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.

Water under the unit
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.

Code 10 or E110
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.

Call (380) 273-8196How much does tankless water heater repair in Bainbridge Island, WA cost?
Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. Freeze repairs depend on what split, and are priced once the damage is seen.
Why is my tankless water heater not turning on?
Check for power at the outlet and that the gas valve is open. Beyond that it is usually low flow, a clogged inlet filter, a failed flow sensor or an ignition fault.
Why does my tankless water heater go hot then cold?
A second or two of cold after the tap reopens is normal start-up. If the water swings while it runs, look at low flow, scale or the flow sensor.
Can a tankless water heater be repaired?
Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
