Call (380) 273-8196What We Repair on Tankless Units in Lake Stevens
Error codes & ignition
Code 11, E003, 111 and their cousins traced to the gas supply, igniter, flame rod or venting, then fixed.

Flow sensors, filters & leaks
Units that shut off mid-shower or drip from below get the flow sensor, filter, valves and fittings sorted.
How a Repair Visit Runs in Lake Stevens
Here is what a visit covers, from the display to the final test, whatever the brand on the cabinet.
- 01
Error history read
- 02
Gas pressure under load
Inlet gas pressure is measured with hot water running, because a supply that looks fine at rest can sag once the burner fires.
- 03
Flow and inlet filter
- 04
Ignition and flame
Igniter, flame rod and burner are inspected and tested. A dirty rod is cleaned; a dead one is replaced.
- 05
Venting and condensate
- 06
Sensors and board
- 07
Fixed, then run hard
After the repair, several taps run at once while the outlet temperature is watched, before the job is signed off.
Tankless Problems We Fix Around Lake Stevens
Most requests for tankless water heater repair in Lake Stevens, WA start with one of the symptoms below, and most end with a single part or a descale.
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.
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.

Fix It or Retire It? Deciding in Lake Stevens
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.

Why Lake Stevens Homeowners Call Us
Parts tested before they're bought
A flow sensor or flame rod gets checked against the maker's values, so you don't pay for a part that wasn't broken.
Scale treated, not ignored
If scale caused the fault, the exchanger is descaled as well, so the same code doesn't return next month.
Run hard before we go
The unit is pushed with several taps open and its outlet temperature watched before the visit ends.

Tankless Water Heater Repair in Lake Stevens, WA: FAQs
Question not covered here?
Call and ask. Someone who repairs tankless units answers, and the phone quote is free.
Call (380) 273-8196How much does tankless water heater repair in Lake Stevens, 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.
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.
What is the most common problem with tankless water heaters?
Scale buildup tops the list, then ignition trouble, then flow sensors and clogged inlet filters.
