Flow Sensor Assembly- QC MED/LRG

Functionality | Troubleshooting

Flow Sensor Assembly FSA QC MED/LRG. This sensor is crucial as it detects water flow, triggering the unit to activate.

Unsure if your flow sensor is the culprit? Here's a quick check: If the unit's LED lights up when you adjust the knob, it means your control board and power supply are functional. However, if the LED fails to illuminate when hot water is running, it's a clear sign that the flow sensor needs replacement. Don't worry, we've got you covered.
