  • the water backlog can become so large that the rotating laundry drum touches the water level of the remindstaumenge or even immersed in the aqueous liquid. This immersion causes increased drive torque of the drum drive and thus leads to increased engine load and increased engine wear.
  • Foaming occurs in a washing machine often due to an incorrect Use of detergent, in particular an overdose, on. But even if, for example, an incorrect selection of a washing program, too much foam can be produced.
  • Foam is a two-phase mixture of air and liquid and thus has a lower density than the wash liquor or a rinsing liquid. This may cause the drive power of the pump to decrease due to the reduction in density and the pump performance to deteriorate further due to separation of the two-phase mixture. An improvement in the pumping performance with regard to the changing conditions during a washing program would therefore be desirable.
