These are the faults behind most calls for tankless water heater repair in Saint Helens, OR. The display usually points at one of them.
Unit won't light
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.
Drip from the cabinet
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.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
Display is blank
No power at the outlet, a blown fuse or a failed control board.

Call (380) 273-8196How much does tankless water heater repair in Saint Helens, 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.
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.
How often should a tankless water heater be flushed?
Once a year for most homes, and twice a year on very hard water. Soft-water homes can stretch it, but never skip it for years.
Is there a reset button on a tankless water heater?
Most units reset by switching power off and on, or through the controller. A reset clears the code, not the cause; ignition and exhaust codes that return need a repair visit.
