The dishwasher or washing machine has a measuring arrangement (12) for measuring parameters depending on surface tension of a laundry sud. The measuring arrangement has a sud chamber (20) with nozzle openings (24, 25). One nozzle opening is arranged higher than the other nozzle opening such that the laundry sud from the sud chamber is entered through the nozzle openings. The measuring arrangement has sensor devices (32, 33) for measuring a drop rate or flow rate or a difference between another drop rate and flow rate.
