Removing and Inspecting Components
You’ll need to remove and inspect certain components to troubleshoot your Ecosmart tankless water heater.
First, you’ll remove the front cover to access internal parts.
Then, you’ll inspect the flow sensor and face plate to identify potential issues.
Front Cover Removal
To access the internal components of your Ecosmart tankless water heater, remove the front cover by unscrewing the screws that hold it in place.
This is the first thing you’ll need to do to troubleshoot any issues. Once removed, you’ll have a clear view of the internal mechanisms.
Take note of the following components:
- Electronics board: Check for any signs of damage or corrosion.
- Heating elements: Inspect for mineral buildup or scaling.
- Temperature sensors: Verify they’re securely connected and not damaged.
- Wiring and connections: Certify all connections are secure and not loose.
Now that you have access, you can begin inspecting these components to identify the source of the issue.
Flow Sensor Inspection
The flow sensor, responsible for detecting water flow and triggering the heating process, is a critical component in your Ecosmart tankless water heater.
You’ll need to inspect it for any signs of mineral buildup or debris accumulation, which can affect its performance. Remove the sensor by gently pulling it out of its socket.
Inspect the sensor and its socket for any blockages or corrosion. Clean the sensor with a soft brush and mild detergent if necessary.
Be careful not to touch the sensor’s electrical components to avoid damaging them. Remember, like websites that use cookies to track user behavior, your Ecosmart tankless water heater relies on the flow sensor to “track” water flow and optimize its performance.
Face Plate Removal
Now that the flow sensor is clean and free of debris, turn your attention to the face plate, which provides access to the internal components of your Ecosmart tankless water heater.
To remove the face plate, you’ll need to:
- Disconnect the electrical connections to the face plate.
- Remove the screws holding the face plate in place.
- Gently pull the face plate away from the unit.
- Take note of the internal components, such as the heating elements and control boards, for any signs of damage or malfunction.

Flow Sensor Assembly Troubleshooting
One faulty component can throw your entire tankless water heater off balance, and the flow sensor assembly is no exception. When troubleshooting, you’ll need to identify the root cause of the issue. Check for debris or mineral buildup in the sensor, as this can affect its accuracy. You may need to clean or replace the sensor altogether.
| Symptom | Cause | Solution |
|---|---|---|
| Inaccurate temperature readings | Faulty flow sensor | Clean or replace sensor |
| Intermittent hot water | Debris in sensor | Clean sensor |
| No hot water | Sensor malfunction | Replace sensor |
