If you own a TOTO Washlet, you already know it’s packed with smart features designed to make everyday life more comfortable and convenient. But with multiple indicator lights and modes across different models, it’s not always obvious what each one means.
This complete TOTO Washlet troubleshooting guide breaks down the most common light signals on the S7A, S5, and S2 models so you can understand what your washlet is telling you and address issues with confidence.
TOTO S7A Washlet Light Meanings
The TOTO S7A is one of the brand’s most advanced washlets, standing out with luxury features like its auto open/close lid, a warm air dryer, and EWATER+® sanitizing technology that cleans the bowl and wand automatically. With all of its built-in technology, the indicator lights play an important role in showing you the status of different operations. Understanding these TOTO Washlet light meanings will help you use the unit more confidently and troubleshoot small issues before they become bigger ones.
Main Display Lights
- Location: Positioned on the left side of the washlet seat just above the hinge area.
- CLEAN Indicator: Indicates when the automatic cleaning or deodorizing cycles are active. When the light is on, a function is currently running and will only operate when the toilet is not in use. When the light is off, no cleaning or deodorizing process is taking place.
- Power LED: Indicates that the washlet is receiving electricity and is ready to operate. When it’s on, it means the unit is powered and functioning normally. When it’s off, it means the washlet has no power.
- Seat LED: Indicates whether the heated seat feature is active. When it’s on, it means the seat-warming function is engaged and maintaining the chosen temperature. When it’s off, it means the seat heater is switched off or has been temporarily reduced by an energy-saving mode.
- Energy Saver LED: Indicates Energy Saver mode is active. When illuminated, the washlet is conserving power by reducing heater temperatures or switching into a low-power standby state.
Energy Saver LED
- Location: The right-most indicator light on the main display panel along the rear edge of the washlet seat.
- Orange: Indicates Auto Energy Saver is active, meaning the washlet is automatically lowering the seat temperature during periods of low or infrequent use to reduce energy consumption. The unit learns your usage patterns over about 10 days and adjusts the seat temperature accordingly.
- Green: Indicates Timer Energy Saver is active, meaning the washlet is following a preset schedule where the seat heater turns off for a set duration each day (such as 6 or 9 hours). The seat temperature will automatically return to normal once the timer period ends.
- Off: Indicates Energy Saver is off, meaning neither Auto nor Timer Energy Saver is running and the seat heater is functioning at the user’s set temperature as normal.
Low Battery Warning Light
- Location: Positioned on the lower-right front edge of the remote control’s outer casing, just beside the TOTO logo.
- Flashing: Indicates the remote control’s batteries are nearly depleted and should be replaced to ensure the remote continues to function correctly. Batteries are a common item in TOTO Washlet troubleshooting.
Soft and Bowl Lights
- Location: The soft light is located on the outer right side of the seat and the bowl light is located along the inner edge of the bowl area.
- Soft Light: Provides a low-glow illumination on the outside of the toilet. When it’s on, the soft light always lights up and automatically adjusts brightness based on movement. When it’s off (or in standby), the soft light operates only according to the normal user settings—typically turning on when the user approaches and turning off after they leave.
- Bowl Light: Illuminates the inside of the toilet bowl. When it’s on, the bowl light turns on only when it detects a person approaching or standing in front of the unit. When it’s off (or in standby), the bowl light behaves according to normal settings rather than night-mode behavior.

TOTO S5 Washlet Light Meanings
The TOTO S5 offers a strong balance of comfort, customization, and reliable performance, making it one of TOTO’s most popular mid-range washlets. The ultra-slim design adds a sleek, modern look to any bathroom, while features like PREMIST® and EWATER+® wand cleaning help keep the toilet cleaner with less effort. The S5 light panel is simpler than the S7A’s but still includes a variety of TOTO Washlet symbols worth understanding. Understanding these will help you get the most out of your S5 and know exactly what the unit is doing.
Main Display Lights
- Location: Positioned on the back-left side of the washlet seat in a small horizontal panel above the seat hinge.
- Power LED: Indicates if the washlet has power and is operating normally. When it’s on, it means the unit is plugged in and functioning. When it’s off, it means the unit is unplugged or shut down.
- Seat LED: Indicates if the heated seat function is operating. When it’s on, it means it’s active and the seat is warming or maintaining temperature. When it’s off, it means there is no heat going to the seat.
- Energy Saver LED: Indicates Energy Saver mode is active. When it’s on, it means the washlet is automatically reducing power usage by lowering heater temperatures or entering standby mode.
- Wand CLEAN LED: Indicates whether the wand cleaning cycle is active. When the light is on, the washlet is currently performing an automatic wand cleaning process. When the light is off, it means no cleaning cycle is running.
Energy Saver LED
- Location: The third indicator from the right on the washlet’s main display panel.
- Orange: Indicates Auto Energy Saver is active, meaning the washlet automatically reduces the seat temperature during times of low or irregular use. The system learns your typical usage over roughly 10 days and adjusts heating levels to conserve energy.
- Green: Indicates Timer Energy Saver is active, meaning it follows a programmed schedule where the seat heater turns off for a predetermined period each day (such as 6 or 9 hours), then resumes normal heating after the timer ends.
- Off: Indicates Energy Saver is off, meaning neither Auto nor Timer Energy Saver is active, and the seat heater operates continuously at the temperature you have set.
Low Battery Warning Light
- Location: On the front lower-right corner of the remote control near the TOTO logo.
- Flashing: Indicates the remote control’s batteries are running low and need to be replaced for it to continue working properly.
Soft Light
- Location: Along the inner edge of the bowl area.
- Soft Light: Lights the interior of the toilet bowl. When it’s turned on, the light stays illuminated continuously. When it’s turned off, the light remains completely off. In Timer Mode, the light operates on a 12-hour cycle and will turn on and off automatically every 12 hours after you select the start time.

When To Seek Professional Help
While most washlet indicator lights simply signal normal operation, some alerts can point to issues that require expert attention. It’s a good idea to call a licensed plumber if your unit continues malfunctioning even after following the steps in your instruction manual, especially if you’ve already tried basic TOTO Washlet troubleshooting.
You should also seek help if you see water around the toilet, notice electrical problems, hear unusual noises, or spot any damage to the washlet or mounting hardware. A licensed plumber can diagnose the issue, prevent further damage, and ensure the bidet remains safe to use.
