Maintenance
Regular maintenance ensures the longevity and optimal performance of your Moen CA8303 faucet.
- Cleaning the Finish: Clean the chrome finish with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Sensor Cleaning: Periodically wipe the sensor window (usually located near the spout base) with a soft, dry cloth to remove any dirt, soap residue, or water spots that might interfere with its operation.
- Aerator Maintenance: If water flow becomes restricted, the aerator may be clogged. Unscrew the aerator from the spout, clean any debris, and reattach it.
- Battery/Power Check: If the faucet is battery-powered (check specific model details), replace batteries as needed. If hardwired, ensure the power connection is secure.
