The Splashguard has 2 purposes. It can be used as a Splashguard during mixing to keep air and ingredients in the bowl and so avoiding creating a mess and it can be used when using the heat function to keep moisture and heat inside the bowl, just like a sauce pan lid. It also has a feed chute through which you can add otheringredients during the cooking process.
The plastic Heat shield protects the motor against the steam generated during cooking. It must be fitted on the machine while using the temperature control, otherwise an error code appears and the heat function doesn’t work.
