If you recently purchased an INAX bidet like the popular Luscence CW-W131, you might feel uncertain about operating its advanced features. These Japanese-style washlets offer superior hygiene through heated seating, dual-nozzle washing, warm air drying, and intuitive remote controls, but mastering all the functions takes a short learning curve. This guide walks you through every step of using your INAX bidet correctly, from activating the wash functions to adjusting settings and performing basic maintenance.
Getting Started: Remote Control Setup
Locating and Mounting Your Wireless Remote
The wireless remote serves as your primary interface with the INAX bidet. It typically comes with a wall-mounting bracket that you should install beside the toilet at a comfortable height for easy access. The remote features a brushed chrome finish with tactile buttons and a small LCD screen that displays real-time settings including water temperature and spray mode.
Mount the remote so your dominant hand can operate it without leaning or stretching. This prevents awkward movements during use and ensures you can access all functions quickly.
Understanding the Button Layout
Each button on the remote serves a specific function, with labels in both English and Japanese. Familiarize yourself with these controls before first use to prevent confusion during operation.
The main buttons include:
- Oshiri: Activates rear (posterior) wash
- Bide: Activates front (feminine) wash
- Stop (止): Ends the current wash cycle immediately
- Dry / Kansou: Activates warm air drying
- Water Pressure: Adjusts spray strength between weak and strong
- Temp Setting: Controls water and seat heat levels
- Nozzle Position: Moves the spray nozzle forward or backward
- Warm Seat: Turns seat heating on or off
- Power: Controls system on and off
- Flush (大/小): Triggers large or small flush
- Deodorizer: Activates the carbon-filter odor removal
- Otohime (Sound): Plays masking water sounds for privacy
Step-by-Step Washing Process
Sitting Position and Initial Setup
Do not wipe after using the toilet before activating the bidet. The bidet cleans most effectively when used directly on the area without prior wiping, as dry paper can interfere with the spray’s cleaning ability. Sit naturally on the toilet seat, ensuring proper alignment over the nozzles for optimal cleaning results.
Wiping first reduces the bidet’s cleaning effectiveness and may spread residue. Let the water do the work instead.
Activating the Wash Function
Press either the Oshiri button for rear cleaning or the Bide button for front (feminine) wash on your remote. The appropriate nozzle will extend from the unit and begin spraying filtered, heated water at your preset preferences. The system delivers instant heating, so the water reaches your desired temperature within seconds.
Select your preferred wash function based on your needs. The rear wash works for general cleansing, while the feminine wash uses a forward-angled nozzle designed specifically for women’s hygiene.
Adjusting Water Temperature and Pressure
Use the Temperature Setting and Water Pressure buttons to customize your washing experience. Most users prefer warm water between 35-40°C (95-104°F), which provides comfortable cleansing without being too hot.
For pressure settings, start with lower pressure if you have sensitive skin or are a first-time user. The weak setting works well for children or those new to bidets, while the strong setting provides thorough cleansing for users who prefer stronger spray. Begin with conservative settings and increase gradually to find your comfort level.
Fine-Tuning Nozzle Position
Press the Nozzle Position button (usually labeled 洗浄位置) to shift the spray forward or backward. This adjustment ensures precise targeting based on your body position and personal preference. Users with mobility issues or those seeking optimal comfort will benefit significantly from this feature.
The nozzle position adjustment is particularly helpful if you find the default position too far forward or backward. Small adjustments can make a big difference in cleaning effectiveness and comfort.
Ending the Wash Cycle
Press the Stop button (止) to immediately halt the wash when finished. If you do not stop the spray manually, it will auto-cancel after 30-60 seconds depending on your model settings. Most users prefer manual control to stop exactly when they feel clean.
Using the Air Dryer and Final Steps
Activating Warm Air Drying
After washing, press the Dry button (乾燥) to activate the warm air dryer. Select your preferred drying time through the remote, typically ranging from 1-3 minutes. The warm air reduces moisture significantly, though most users follow with a light pat using a small amount of toilet paper for complete dryness.
The dryer reduces toilet paper use by up to 75%, but it may not replace wiping entirely. A light pat dry ensures you finish completely clean and dry.
Flushing the Toilet
Use the flush controls to empty the toilet. Press the large flush button (大) for solid waste or the small flush button (小) for liquid waste. Some models integrate flush buttons directly on the remote, while others use a lever on the toilet tank.
Efficient flushing ensures waste is properly removed and maintains bathroom hygiene. Choose the appropriate flush setting to conserve water while ensuring cleanliness.
Exiting the Toilet
Stand up and allow the slow-close lid to shut quietly. The slow-closing mechanism prevents slamming and adds to the premium feel of your INAX bidet. In higher-end models, the lid may close automatically via sensors when you approach or walk away.
The slow-close feature is especially valuable in households with children or during nighttime bathroom use when quiet operation matters.
Using Advanced Features
Heated Seat Operation
Press the Warm Seat button to turn on seat heating, then adjust the warmth level using the temperature controls. The heated seat eliminates the shock of cold toilet seats during winter months and adds significant comfort to your bathroom experience.
You can disable heated seating if you prefer ambient temperature or find it too warm. Using energy-saving mode reduces power consumption when the seat heating is not needed.
Feminine Wash Best Practices
The Bide function uses a forward-angled nozzle designed specifically for female intimate hygiene. Use this function during menstruation or daily hygiene routines for gentle, effective cleaning. Select low to medium pressure and warm water for the most comfortable experience.
Do not use the feminine wash during pregnancy or post-surgery without consulting your doctor if you have been advised to avoid such activities. The gentle spray is generally safe but follow medical guidance when appropriate.
Activating the Deodorizer
Press the Deodorizer button (パワー脱臭) to turn on the carbon-filter fan that removes bathroom odors. The system activates automatically or on demand, making it ideal for small bathrooms or shared living spaces. Replace the carbon filter every 6-12 months when odor control declines.
The deodorizer runs quietly in the background, continuously filtering air to maintain a fresh bathroom environment. This feature is especially useful in bathrooms without windows or with limited ventilation.
Using Otohime for Privacy
Press the Otohime button (音姫) to play masking water sounds that enhance privacy during bathroom use. This feature proves particularly useful in offices, guest bathrooms, or any situation where sound privacy matters.
The water sound masks natural bathroom noises, providing discretion in shared or public-style bathrooms. Many users find this feature invaluable for maintaining privacy in multi-person households.
Maintaining Your INAX Bidet
Nozzle Self-Cleaning System
INAX bidets automatically clean the nozzles before and after each use. A brief rinse occurs before use to clear any residue, followed by a full wash and retraction after use. No manual cleaning of the nozzles is required, as the system maintains hygiene automatically.
Never touch or wipe the nozzles, as this can damage the sensors or introduce bacteria. The self-cleaning function handles all necessary hygiene maintenance.
Cleaning the Water Inlet Filter
The inlet filter prevents sediment from entering the bidet system and should be cleaned every 1-3 months depending on your water quality. Turn off the water supply, remove the filter from the T-valve, rinse it under running water, then reinstall and restore water flow.
Signs of a clogged filter include reduced spray pressure, sputtering, or weak water flow. Regular cleaning ensures consistent performance and extends the life of your bidet.
Replacing the Deodorizer Filter
When the deodorizer loses effectiveness, replace the carbon filter by opening the filter compartment (usually located under the seat), removing the old filter, inserting a new INAX-compatible filter, and resetting the indicator if your model has one. Replace the filter every 6-12 months for optimal odor control.
Reduced odor removal performance signals that filter replacement is needed. Keep spare filters on hand for convenient maintenance.
Descaling for Hard Water Areas
In regions with hard water, perform annual descaling using a manufacturer-recommended solution to prevent mineral buildup. Follow INAX guidelines to flush internal water pathways and maintain optimal spray performance.
Hard water areas require more frequent maintenance to prevent mineral deposits from affecting spray quality and heating efficiency.
Troubleshooting Common Issues
No Water Spray Problems
If no water sprays despite activating a wash function, check that the water supply is fully open, the inlet filter is clean with no debris, the T-valve is properly connected, and the nozzle is not clogged. Verify that the unit is powered on and the remote is functioning correctly.
If the problem persists after checking these items, reset the power by unplugging the unit for 30 seconds and plugging it back in. Consult your manual for specific error codes if displayed on the remote.
Seat Not Heating
Possible causes for a non-heating seat include the power being turned off, a tripped GFCI circuit, or the heater being in energy-saving mode. Ensure the unit is powered on and check that the GFCI outlet has not tripped. Verify the heated seat function is enabled through the remote.
The energy-saving mode may have activated automatically after a period of inactivity. Press the Warm Seat button to reactivate heating if needed.
Dryer Not Functioning
If the air dryer fails to work, confirm that drying time is set on the remote and check for any obstructions in the air vent. Clean any accessible lint filter and verify the dryer is not in a disabled state. If the motor fails after five or more years of use, replacement may be necessary.
Regular maintenance of the dryer vent prevents lint buildup that can reduce performance or cause malfunctions.
Safety Guidelines and Best Practices
Electrical Safety Requirements
Always plug your INAX bidet into a grounded GFCI-protected outlet to prevent electrical shock in wet bathroom environments. Never use extension cords or power strips with your bidet, as these can create safety hazards.
Install a dedicated GFCI outlet near your toilet if one does not exist. This ensures safe operation and meets electrical code requirements for wet locations.
Emergency Features
Some INAX models include a red or yellow emergency call button labeled “yobidashi” for medical emergencies, commonly found in accessible toilet models. Do not press this button unless needed, as it may trigger an alarm or alert system.
Familiarize yourself with all button functions before first use to avoid accidentally activating emergency features.
Child and Elderly Use
Children can use the bidet safely with adult supervision. Use low pressure and temperature settings, and disable the heated seat if it becomes too warm. Teach children proper remote operation before allowing independent use.
The bidet proves ideal for elderly users who need hands-free cleaning and easy access. The remote control eliminates the need for reaching or twisting, reducing strain on joints and muscles.
