The list below covers what we find on most visits for tankless water heater repair in Lake Oswego, OR, 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.
Shuts off mid-shower
Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.

Call (380) 273-8196How much does tankless water heater repair in Lake Oswego, OR 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.
How often should a tankless water heater be flushed?
Most makers call for a flush every year, and every six months on very hard water. On very soft water the gap can be longer, but skipping it for years invites scale faults.
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.
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.
