If you follow the operation steps on how to make the soymilk in our user manual, the overflowing situation should not happen in normal use. However, should this situation happen, there could be several reasons:
- Select the wrong function. For instance, you want to make nutritional rice paste, but you accidentally select bean Soymilk function.
- Wrong quantity of ingredients and/or water amount.
- The overflow sensor is not clean, which causes it not able to detect overflow.
- During processing, there is a temporary power outage which disrupt the operations, and then restart the processing again.
- Water temperature is too high, please use water at normal temperature.
- Vent valve is blocked.
- The sealing ring isn't assembled correctly.
- Power supply is abnormal.
If still happen, please contact the Philips Consumer Care Center for maintenance.
