5.4 Advanced Cleaning Technologies

• EWATER+: Electrolyzed water mists the wand and toilet bowl, reducing the need for harsh cleaning chemicals and promoting hygiene.
• PREMIST: Wets the surface of the toilet bowl before each use, aiding in the removal of waste and resulting in a better clean.
• TORNADO FLUSH: A hole-free rim design with dual-nozzles creates a powerful centrifugal washing action that efficiently rinses the bowl.

6. Maintenance

6.1 CEFIONTECT Glaze

The toilet bowl features CEFIONTECT, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. This smooth, ion-barrier surface helps keep the bowl cleaner for longer.

6.2 Routine Cleaning

The combination of CEFIONTECT, EWATER+, and TORNADO FLUSH optimizes performance to reduce the frequency of toilet cleanings and minimize the usage of water and harsh chemicals.

• For daily cleaning, use a soft cloth and mild, non-abrasive cleaners.
• Avoid using harsh chemicals, abrasive pads, or brushes that could damage the CEFIONTECT glaze or WASHLET components.
• Regularly clean the bidet wand according to the WASHLET S7A specific instructions (EWATER+ assists in this).
• The skirted design of the toilet minimizes hard-to-reach areas, simplifying exterior cleaning.

7. Troubleshooting

If you encounter issues with your TOTO WASHLET+ Nexus system, consider the following common troubleshooting steps:

• No Power to WASHLET: Check if the power cord is securely plugged into a functional outlet. Verify the circuit breaker.
• No Water Spray: Ensure the water supply valve is fully open. Check for any kinks in the water supply hose.
• Weak Water Spray: Clean the bidet nozzle. Check water pressure from the main supply.
• Toilet Not Flushing: Ensure the Auto Flush sensor is clear. If manual flush is available, test it.
• Remote Control Not Responding: Check the remote's batteries. Ensure there are no obstructions between the remote and the WASHLET sensor.
