1. A method for computer-assisted determination of clusters for recognizing foam formation in a washing machine, comprising the steps of:
- measuring a set of quantities during a washing process, the set of quantities having at least the quantities of a pressure in the washing machine, a temperature in the washing machine, an amount of water in the washing machine;
forming training data vectors from the measured quantities; and
identifying, dependent on the training data vectors, clusters which indicate if a foam formation is to be anticipated for a set of measured quantities.

Abstract
A method and arrangement for computer-assisted determination of clusters recognizes foaming in a washing machine. The following quantities are measured during a washing process in the washing machine; a pressure in the washing machine, a temperature in the washing machine, and an amount of water in the washing machine. Application vectors are formed from the measured quantities, and fuzzy affiliation values for predetermined clusters are identified for the application vectors. A foam formation is recognized based on the fuzzy affiliation values.
