Tankless Units in Flossmoor Homes
In Flossmoor, basement units with PVC sidewall vents are typical. Scale from the hard water and snow at the termination are the faults we see most.
What we run into in Flossmoor
- 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.
- Hard water. Scale is the slow problem in this area: it narrows the waterways, trips temperature limits and shortens the life of the exchanger if nobody flushes it.

Most requests for tankless water heater repair in Flossmoor, IL start with one of the symptoms below, and most end with a single part or a descale.
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.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
Shuts off mid-shower
Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.

Call (380) 273-8196How much does tankless water heater repair in Flossmoor, IL 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 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.
Why is my tankless water heater not turning on?
Check for power at the outlet and that the gas valve is open. Beyond that it is usually low flow, a clogged inlet filter, a failed flow sensor or an ignition fault.
What is the most common problem with tankless water heaters?
Scale in the heat exchanger, followed by ignition faults and flow sensor or filter problems. All three usually show up as a code or as water that won't stay hot.
