The list below covers what we find on most visits for tankless water heater repair in Milton, WA, from ignition codes to drips under the cabinet.
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
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.
Venting fault
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Hot, then cold, then hot
A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.

Call (380) 273-8196How much does tankless water heater repair in Milton, 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 does my tankless water heater go hot then cold?
A brief cold slug after a tap reopens is the unit restarting. Swings during one shower usually mean flow below the unit's minimum, scale on the exchanger, or a failing flow sensor.
Can a tankless water heater be repaired?
Usually, yes. Nearly every part on a tankless unit can be replaced, and a scaled exchanger can be cleaned. The exception is an old unit whose heat exchanger has started to leak.
How long does a tankless water heater last?
Gas units commonly run 20 years or more when they are flushed on schedule. Electric tankless units tend to last closer to 7 to 10 years.
