Tankless Units in Wixom Homes
In Wixom, basement installs are the norm, and the water is hard. Scale on the exchanger and frozen condensate lines are frequent calls.
What we run into in Wixom
- 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.
- Freeze damage. A hard freeze can split the pipes feeding a unit. Its built-in freeze protection only works while the unit still has power and gas.
- Hard water. Mineral-heavy water coats the exchanger a little more every month. Many repair visits here end with a descale as well, so the fix holds.

Call (380) 273-8196Tankless Problems We Fix Around Wixom
The list below covers what we find on most visits for tankless water heater repair in Wixom, MI, from ignition codes to drips under the cabinet.

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.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.

Call (380) 273-8196How much does tankless water heater repair in Wixom, MI 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. On hard water, a descale often goes with the repair and sits on the same written quote.
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 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.
What is the most common problem with tankless water heaters?
