About Tankless Water Heater Flow Sensor Repair

Tankless water heaters do not run continuously; they only wake up when an internal flow sensor detects water moving through the system in Evergreen Park, Illinois. If mineral sediment, pipe scale, or plastic turbine wear jams the internal flow impeller, the unit cannot detect when a faucet opens. The display remains dark, the fan stays off, and water flows ice-cold. Our service technicians remove and inspect magnetic turbine impellers, clear inlet debris screens, and test hall-effect electrical pulses. We restore instant firing capability so your unit responds immediately even to low-flow fixtures.

Common Problems We Solve With Tankless Water Heater Flow Sensor Repair

Unit Fails to Recognize Water Flow

Hot water faucets run wide open but the tankless heater never attempts to fire in Evergreen Park, Illinois.

Jammed Turbine Impeller

Plumbing construction debris or calcium flakes jam the spinning magnetic wheel.

High Activation Threshold

The heater only turns on when three faucets open, ignoring single low-flow fixtures.

How Our Tankless Water Heater Flow Sensor Repair Process Works

1

Inlet Filter Inspection

We remove and clean the cold water inlet screen filter in Evergreen Park, Illinois.

2

Impeller Voltage Output Test

Our tech measures DC frequency pulses from the hall-effect sensor while water runs.

3

Flow Sensor Replacement

Benefits of Professional Tankless Water Heater Flow Sensor Repair

Low-Flow Activation

Allows eco-friendly 0.4 GPM bathroom faucets to trigger reliable hot water.

Cleans water passages to protect downstream valves and fixtures from grit.

Accurate Modulation

Ensures the control board calculates exact firing rates for target temperatures.

Tankless Water Heater Flow Sensor Repair Pricing Factors

Sensor Access Location

Sensors buried behind recirculation loops or internal piping require more labor.

Inlet Plumbing Condition

Corroded or frozen isolation shutoff valves requiring replacement increase project cost.

Brand Sensor Sourcing

OEM hall-effect flow turbines vary in price across international manufacturers.

Tankless Water Heater Flow Sensor Repair Questions

Why does my tankless water heater not turn on when I open the faucet in Evergreen Park, Illinois?

A stuck flow sensor impeller or clogged inlet filter screen is usually preventing water flow detection. Call (888) 905-6092 to fix it in Evergreen Park, Illinois.

What is the minimum flow rate required for a tankless heater to fire?

Most modern units require between 0.4 and 0.6 gallons per minute to activate. Call (888) 905-6092 to calibrate low-flow response.

Can a flow sensor be cleaned or does it have to be replaced?

If mineral scale is jamming the wheel, cleaning often restores it. If internal magnets or sensor electronics fail, we replace it. Call (888) 905-6092.

What Our Customers Say

Real reviews from property owners we have helped restore to endless hot water.

Our Navien unit flashed error E003 on a cold morning and stopped heating completely. The technician arrived with the exact OEM flame sensor rod on his truck, tested the gas manifold pressure, and had hot water flowing again within an hour. The diagnostic explanation was clear and pricing was fair.

Our Rheem tankless system kept shutting down during showers with code 12. Two other plumbers told us we needed a new unit, but this team discovered a clogged condensate trap and an oxidized flame sensor. They cleaned the burner assembly and saved us thousands compared to a premature replacement.

Elena Rostova

Hard water scale choked our Rinnai heat exchanger to the point where shower pressure dropped to a trickle. Their technician hooked up a high-volume descaling pump and circulated food-grade solution for over an hour. The difference in water pressure and heating speed was immediate.
