Frequently Asked Questions
The lid should always be in place while the appliance is in operation.
To add ingredients during mixing, remove the feeder cap and insert the ingredients through the filling hole in the lid.
If your appliance has this function, it allows you to make crushed ice, smoothies or frozen drinks by using the motor pulse function.
Always pour the liquid ingredients into the jug first before adding the solid ingredients, without exceeding the maximum level indicated.
For best results the food should be cut into cubes of 2 to 3 cm maximum before blending it.
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.
The chopper can be used for parsley, garlic, onions, bread, nuts, etc.
Use the "pulse" function for 2 second bursts each time, for a maximum period of 3 minutes.
Stop and leave the blender on pause for 15 minutes before restarting.
To clean the body of the appliance, first of all unplug it and then wipe it with a damp cloth.
To clean the bowl, use soapy water or washing-up liquid.
Some bowls are dishwasher safe, see instructions for use.
This is probably due to the fact that there is too much food, or that the pieces are too large or too hard. To correct this, reduce the size or the quantity of ingredients or add a little liquid.
The appliance may not be on a flat, stable surface, the appliance is not stable (foot missing, etc.).
The volume of ingredients to be blended is too high, reduce the quantity of ingredients.
If the vibrations persist, contact an approved repair centre.
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.
If the lid has a seal, check its condition and change it if necessary.

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.
• If your appliance has a removable blade unit: check it is positioned correctly on the jug. 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.

• Check the condition of the seal/gasket and change it if necessary.
• Check that your bowl is not split or broken as a result of impact.

If the leak persists, take the appliance to an approved repair centre.
After following the instructions in the user manual for starting the appliance, make sure that your electrical socket is working by plugging another appliance. If it still does not work, do not try to dismantle or repair the appliance yourself, instead, take it to an approved repair centre
Do not use your appliance. To avoid any danger, have it replaced by an approved repair centre.
Your appliance contains valuable materials which can be recovered or recycled. Leave it at a local civic waste collection point.
