Troubleshooting My Avent Combined Steamer and Blender won't steam If your Philips Avent Combined Steamer and Blender does not steam or does not steam properly, we are here to help. Just follow these steps to resolve it yourself. Easy fix There can be several reasons why the steam function does not work (properly): There is too much scale in the water tank. For descaling the water tank see corresponding Frequently Asked Questions - Chapter 'Cleaning and maintenance'. After one steaming cycle, the device needs about 10 minutes to cool down before a new steaming cycle can be started. Try again after 10 minutes. Make sure that you have positioned the jar in the right way (steaming position). Still not working? If the steam function is still not working, it could be that the safety switch is defective.
