    Service Manual 23. Programme unit Imbalance detection Imbalance can be split into three different types: extreme imbalance measurement, mechanical imbalance interruption and super imbalance measurement. Extreme imbalance measurement In a drain sequence, when the drum starts its acceleration from washing rpm to extraction rpm, the extreme imbalance measurement starts when 90% of the distribution rpm has been achieved.
  • Page 98 Service Manual 23. Programme unit Super imbalance measurement Super imbalance measurement is the normal imbalance measurement. Its task is to ensure that the machine is not overloaded during extraction, as well as to ensure that the number of missed extractions is as small as possible.
