Troubleshooting
If you encounter issues with your TOTO Drake WASHLET+ system, please refer to the following common solutions:
- No Power to WASHLET: Check if the power cord is securely plugged into a grounded outlet. Verify the circuit breaker has not tripped.
- No Water Spray: Ensure the water supply valve to the toilet is fully open. Check for any kinks in the water supply hose.
- Weak Spray Pressure: Adjust the water pressure setting on the remote control. Clean the wand nozzle if it appears clogged.
- Toilet Not Flushing: For auto-flush models, ensure the sensor is clean and unobstructed. Manually flush if the auto-flush is unresponsive.
- Unusual Noises: Minor sounds during operation (e.g., water heating, fan) are normal. If loud or persistent, contact customer support.
