7. Risoluzione Dei Problemi
Refer to the following common issues and solutions. If the problem persists, contact TOTO customer service.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Wand extends unexpectedly. | Self-cleaning function initiated. | This is normal operation. The wand extends to clean itself before and after use. |
| Spray function does not activate. | Seat sensor not engaged. | The WASHLET features a seat sensor to prevent the wand from spraying when no one is seated. Ensure you are seated properly. To test, press the seat down until you hear the sensor click, then cover the spray from the wand with a cup. |
| Water pressure is too soft. | Low pressure setting or insufficient water supply. | Adjust the water pressure setting on the remote control. Ensure the water supply valve is fully open. The rear spray has two options: soft (single press) and strong (double press). |
| Niente acqua calda. | Temperature setting too low or power saving mode. | Adjust the water temperature setting on the remote. Check if the power saving mode is active and adjust if necessary. |
