Tankless Units in Fort Washington Homes
Most Fort Washington homes keep the tankless in the basement or a utility room, with the vent through the side wall. Winter cold snaps and condensate drains cause the usual trouble.
What we run into in Fort Washington
- Basement units. Many units here sit in the basement with PVC pipes venting out through the rim joist, and the condensate has to drain somewhere sensible.
- 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.

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

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
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.

Code 10 or E110
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
Can't tell which one you have? Read us the display and describe the water, and the likely fault comes back on the call.

Fix It or Retire It? Deciding in Fort Washington
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.

Fort Washington Homes by the Numbers
Heating in Fort Washington splits between gas (about 44% of homes) and electricity (about 44%), and tankless repairs follow the same split. The median home here dates from 1980, so tankless units are a mix of original-era installs and newer replacements, and an older unit that has never been descaled is a frequent find. About 91% of homes are owner-occupied and about 99% are single-family, so most repair decisions here are the homeowner's own.

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.
How long does a tankless water heater last?
A gas unit that is flushed regularly commonly lasts 20 years or longer. Electric tankless models usually give 7 to 10.
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.
