Tankless Units in Bountiful Homes
In Bountiful, most tankless units live in the basement. Thin air, hard water and winter cold are the three things behind most faults.
What we run into in Bountiful
- Hard water. The water here carries a lot of minerals, and they settle as scale inside the heat exchanger. LC codes, overheat faults and water that will not get hot often trace back to it.
- Altitude setting. Thinner air changes combustion. If the altitude setting was skipped at install, flame faults can follow the unit for years.
- Freeze damage. Cold snaps do damage here when the power drops overnight. A frozen line or a cracked fitting under the unit is a repair we see after every deep freeze.

These are the faults behind most calls for tankless water heater repair in Bountiful, UT. The display usually points at one of them.

Code 11, E003 or 111
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
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.

How long does a tankless water heater last?

Can a tankless water heater be repaired?
Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
Why does my tankless water heater go hot then cold?
A second or two of cold after the tap reopens is normal start-up. If the water swings while it runs, look at low flow, scale or the flow sensor.
