The original Magefesa spare part should be replaced in the following way:

• Remove the old silicon gasket.
• Put new silicon Magefesa gasket in place of the faulty one.
• The silicon gasket is made from durable materials. Wash with warm water and a neutral soap. Dry the lid and gasket with a soft cloth and place correctly after each use.
• When storing, place the lid facing downwards allowing for ventilation.
