The programme duration changes during the wash cycle

Programme duration changes — Electronic optimization or unbalance

Bosch · Washing Machines

What does The programme duration changes during the wash cycle mean?

The displayed time for the wash programme varies during operation. This can be due to electronic optimization or the unbalanced load detection system adjusting for an imbalance.

Common Causes

  • The programme operation is optimised electronically.
  • Unbalanced load detection system eliminates an imbalance by repeatedly redistributing the laundry.
  • Foam detection system switches on a rinse cycle if foam build-up is too high.
