A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.

Drip from the cabinet

The unit is reporting scale buildup. It needs a descale, and soon.

Noisy or whistling

Fix It or Retire It? Deciding in Kettle Falls
Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.
Read the model and serial off the label and call (380) 273-8196. The age and the fault together usually settle repair versus replace on the phone.

Kettle Falls Homes by the Numbers
Gas heats about 51% of homes in Kettle Falls and electricity about 40%, so both gas and electric tankless units turn up on calls here. Housing here is older (median year built 1979), and older homes were plumbed and vented for tank heaters, so tankless retrofits often meant new gas lines, venting or a condensate drain, which are common places for faults to start. Kettle Falls is about evenly split between owners (around 57%) and renters, so calls come from homeowners and from landlords and property managers alike.
Kettle Falls covers about 1.1 square miles and holds roughly 1,703 residents, around 1,534 per square mile: spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. It is number 124 by population of the 209 Washington places on our service list.

Kettle Falls Weather and Water Temperature
Winter here is long: roughly 185 nights a year drop to freezing or below, and the lowest reading in the past three years was about -21°F. Condensate traps, supply stubs in unheated spaces and vent caps are the usual victims, so a tankless unit in Kettle Falls deserves a close look before the cold sets in.
Water arriving at a Kettle Falls tap in winter is likely near 38°F (averages of about 26°F in January air and 49°F over the year). To reach 120°F a tankless unit must add roughly 82°F, which a 199,000 BTU gas model at 90% efficiency can do for about 4.4 gallons per minute. In July the water is nearer 64°F, so the same unit has to add only about 56°F and can supply about 6.4 gallons per minute.
Since a shower uses about 2 gallons per minute, that winter ceiling is why a heater that handles one shower easily can run lukewarm when a second shower and the dishwasher start. Lukewarm water at full demand is a limit of the design, not always a fault, whereas lukewarm water at a single tap points to scale, a sensor or an ignition problem.
At about 1,627 ft above sea level, Kettle Falls is below the roughly 2,000 ft mark where manufacturers usually begin to adjust gas appliance ratings, so altitude is not a factor for most tankless units here.

Tankless Water Heater Repair in Kettle Falls, WA: FAQs

Question not covered here?

Call (380) 273-8196How much does tankless water heater repair in Kettle Falls, 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.
What is the most common problem with tankless water heaters?
Scale in the heat exchanger, followed by ignition faults and flow sensor or filter problems. All three usually show up as a code or as water that won't stay hot. In Kettle Falls, cold nights add vent-cap, condensate-line and exposed-pipe problems to the usual list.
Is there a reset button on a tankless water heater?
Many do it through power: switch the unit off, wait, switch it back on. That clears a code, but a code that comes back means a part needs attention.
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. In Kettle Falls, after a hard freeze also check whether the condensate line has frozen, since many condensing models shut down when it blocks.
