<p>The method involves switching on and raising of a circulation pump at an operating speed (n1). The speed of a circulation pump is lowered to a speed (nA) for producing a friction of a liquid present at a hydrodynamic sliding bearing. A water change is executed at lowered speed. The speed is increased to an operating speed (n2). The lowering, executing and increasing processes are repeated. The circulation pump is switched off. A rinsing liquid of a dishwasher is circulated by the circulation pump.</p> |
