Abstract: In a method for operating a washing machine, a defined degree of wetting of items of laundry in the drum is required. This degree is brought about in determinable manner by alternately wetting the items of laundry in the drum from below and from above. At intervals, the items of laundry can be tumbled together or loosened up by rotation of the drum. The volume of water absorbed by the items of laundry can be determined by determining the total volume of water admitted into the washing machine and making a comparison with the volume of water not absorbed by the items of laundry. This absorbed water is assumed to be uniformly distributed within the items of laundry and a level of drenching or degree of wetting of the items of laundry can accordingly be determined. In this way, subsequent washing processes can be carried out in a more defined and overall better way.

Abstract: In a method for operating a washing machine with a drum, a drive motor for the drum, a power supply for the drive motor and a washing machine control monitoring and detecting the motor current by means of the power supply, the following steps are performed where the motor current is constantly monitored while the drum rotates for at least three full revolutions. A full revolution of the drum is divided into three rotation sections of equal size, and the motor current is monitored and recorded for each of the rotation sections. An envelope curve of this motor current is calculated, and therefrom the standard deviation is calculated. The standard deviation is divided by the mean value of the envelope curve to determine the coefficient of variation for each rotation section.

The washing machine also has a pump, a filter between the outflow and the pump and a water-guiding system with water lines, valves, the pump and the filter. A flexible or bendable flex line adjoins the outflow, which line extends at an angle of between 15° and 0° to the vertical from the outflow at the bottom, wherein a substantially horizontally extending telescopic line of variable length, which leads to the filter, adjoins the flex line. A drain valve, which may be configured as an actively closable valve or as a nonreturn valve, is arranged between the telescopic line and the filter. The filter is in turn arranged at a short distance downstream of the drain valve.

Abstract: In a method of operating a washing machine, different values for the power required by a drive motor of a drum of the washing machine to accelerate the drum from 30 rpm to 80 rpm are measured and stored as reference values. They can be differentiated by weight or load of laundry, potentially also by different types of laundry. These values are then compared to values derived from an actual washing or dry-spinning process, respectively. As a result of this comparison, it can be determined which values actually measured correspond sufficiently to stored values, and then the load can be determined from this result.
