Centrifugal pump cover

A cover for a centrifugal pump for a liquid of a household appliance, the cover comprising

• a wall having
• an inner face intended to come into contact with the liquid and
• an outer face, opposite to the inner face,
• an electric resistor for heating the liquid, fixed to the cover and having
• a heating stretch, and
• two end stretches connected to the heating stretch;
• at least one safety device sensitive to the temperature of the electric resistor, fixed to the outer face;
• and
• at least one control device sensitive both to the temperature of the liquid and to the temperature of the electric resistor, fixed to the outer face,
• wherein the electric resistor crosses the cover so that
• the heating stretch is arranged on the side of the inner face whereby the heating stretch is adapted to be in contact with the liquid,
• and so that
• the two end stretches project from the side of the outer face,
• wherein at least one first portion of the heating stretch is in contact with the inner face, and
• wherein at least one second portion of the heating stretch is spaced apart from the inner face.
