Tankless Units in Washington Homes
Most Washington homes keep the tankless in the basement, beside the furnace. Hard water and cold winters are what wear these units down.
What we run into in Washington
- 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.

These are the faults behind most calls for tankless water heater repair in Washington, MO. 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
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.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
Display is blank
No power at the outlet, a blown fuse or a failed control board.

Washington Homes by the Numbers
Heating in Washington splits between gas (about 30% of homes) and electricity (about 68%), and tankless repairs follow the same split. Housing here is older (median year built 1978), and older homes were plumbed and vented for tank heaters, so tankless retrofits often meant new gas lines, venting or a condensate drain, which are common places for faults to start. About 70% of homes are owner-occupied and about 77% are single-family, so most repair decisions here are the homeowner's own.
Washington covers about 10 square miles and holds roughly 14,948 residents, around 1,492 per square mile: spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. It is number 17 by population of the 31 Missouri places on our service list.

Call (380) 273-8196How much does tankless water heater repair in Washington, MO 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.
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.
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.
Why is my tankless water heater not turning on?
First confirm power and gas. If both are there, the usual causes are low flow, a dirty inlet filter, a bad flow sensor or an ignition fault.
