No, do not put the bowl in a microwave oven.
Before using it for the first time, we recommend that you wash all the blender accessories in hot soapy water, taking care not to injure yourself with the blades, which are extremely sharp. It is not necessary to wash the body of the blender before use.

Leak through lid (overflow):
• The volume of ingredients is too high, do not exceed the maximum filling level for the bowl as stated in the instructions for use.
• The lid is not correctly positioned, lock it securely on the mixer bowl.

Leak from the bottom of the bowl:
• Your appliance does not have a removable blade unit: the seal on your blade unit may be damaged, have it checked by an approved repair centre.

You need to ensure that the black notches on the blade unit are fitted fully into the equivalent recesses on the base of the jug – this will be apparent if you cannot turn the blade unit any further and if you turn the jug upside down you should not be able to see any gaps between the jug and the blade unit.

• Check that the gasket/seal is positioned the correct way around on the blade unit - the 3 folds of the gasket/seal must be visible once it is in place. If it is positioned in the other direction, you will not be able to lock the blade unit on the jug.
