Tankless Units in Salem Homes
Many Salem cellars hold several tankless units side by side. When one throws a code, gas pressure with the others firing is tested too.
What we run into in Salem
- Basement units. In a basement install, a clogged condensate trap or a failed pump can shut the unit down with a code long before anyone sees water.
- Snow on vents. After a big storm, a buried intake or exhaust is one of the first things to check when the hot water quits.
- Retrofit installs. Retrofits are common in this housing stock. When a unit throws flame codes only while the furnace or dryer runs, the gas supply is the first suspect.

Tankless Problems We Fix Around Salem
Most requests for tankless water heater repair in Salem, MA start with one of the symptoms below, and most end with a single part or a descale.
Code 11, E003 or 111
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
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.

Fix It or Retire It? Deciding in Salem
Igniters, flame rods, sensors, fans, gas valves and boards are worth replacing on almost any unit. The hard call is a leaking or cracked heat exchanger on an older unit, because that part can approach the price of new.
