These are the faults behind most calls for tankless water heater repair in Medina, WA. 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
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.

Medina Homes by the Numbers
Gas heats about 79% of homes in Medina, so gas tankless units, with their vent runs and gas-line sizing, are the usual case on a call. With a median build year of 1974, many homes in Medina were set up for a tank heater, which means a tankless unit often depends on a retrofitted gas line, vent run or drain. Owners live in about 79% of Medina homes (single-family about 99%), so the person who calls is usually the person who decides.
Medina covers about 1.4 square miles and holds roughly 2,889 residents, around 2,006 per square mile: spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. It is number 106 by population of the 209 Washington places on our service list.

Medina Weather and Water Temperature
Freezing nights are not constant in Medina, about 30 a year, but the coldest one in the last three years reached about 16°F. A unit mounted outdoors or in an unheated garage is exposed on those nights, and a leak found in spring often started in January.
Water arriving at a Medina tap in winter is likely near 47°F (averages of about 42°F in January air and 53°F over the year). To reach 120°F a tankless unit must add roughly 73°F, which a 199,000 BTU gas model at 90% efficiency can do for about 4.9 gallons per minute. In July the water is nearer 60°F, so the same unit has to add only about 60°F and can supply about 6.0 gallons per minute.
For comparison, a shower draws roughly 2 gallons per minute, so two at once plus the dishwasher can pass the winter figure. If the water goes lukewarm only when several taps run, the unit is likely maxed out; if it goes lukewarm at one tap, the cause is more often scale, a flow sensor or the flame.

Call (380) 273-8196How much does tankless water heater repair in Medina, 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.
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.
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. In Medina, with winter tap water near 47°F, a gas unit can hold 120°F for about 4.9 gallons per minute, and opening a second tap past that point is a common cause of the swing.
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. In Medina the heat exchanger works through a rise of about 73°F on a typical winter day, which is why flushing on schedule matters there.
