Maintenance
Cleaning the Shower System
To maintain the polished chrome finish and ensure optimal performance, clean the shower system regularly. Use a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome finishes. Avoid harsh chemicals, abrasive cleaners, or scouring pads, as these can damage the finish.
Nozzle Maintenance
The shower head and body jets feature self-cleaning silicone nozzles. Periodically rub the nozzles with your finger or a soft brush to dislodge any mineral buildup and maintain consistent water flow.
Troubleshooting
If you encounter any issues with your NWIASS shower system, please refer to the following common troubleshooting steps:
- No Water Flow or Low Pressure: Check the main water supply valves. Ensure no blockages in the shower head or hose. Clean the silicone nozzles as described in the Maintenance section.
- Inconsistent Water Temperature: Verify that the hot and cold water supplies are correctly connected. Ensure the thermostatic control knob is set correctly and the safety button is not stuck.
- LED Lights Not Working: Check the power supply connection to the LED system. Ensure the remote control batteries are functional and the remote is within range.
- Bluetooth Connection Issues: Ensure your device's Bluetooth is enabled and the shower system is discoverable. Try restarting both your device and the shower system's power.
- Leaks: Check all connections for tightness. Ensure O-rings and seals are properly seated. If leaks persist, professional assistance may be required.
