  • Page 17: Spin Types

    2.4 TYPES OF SPIN CYCLE 2.4.1 Anti-unbalancing during spinning The check for balancing of the wash load is performed while the drum rotates at a speed of 85 rpm, before the spin phase. If the wash load is unbalanced, the spin cycle is not carried out; after rotating the drum several times at low speed in alternate directions, the spin cycle is restarted.

  • Page 19: Attention To The Operating Particularity

    2.5 ATTENTION TO THE OPERATING PARTICULARITY! In order to avoid unnecessary operations on models with VS81 timers, we point put some particularity which characterise their operating. 2.5.1 Rapid advances in 90/60°C cotton cycles As may be seen from the timer diagrams, the programmes in question are started in steps 3 – 5. When the appliance is switched on, the timer advances rapidly to a position between the starting points for COTTON 60 and 40 programmes, during which the water fill takes place.

  • Page 21: Configuration Of Timer Functions

    Depending on the closure of a series of contacts (8-9-10), the timer transmits to the electronic control board (14) the codes which determine the operations to be carried out at the various steps. The electronic control board, on the basis of the appliance configuration and of the selected options (push- buttons and selectors) controls the washing cycle: •...
