The control procedure for unbalanced loads is performed dynamically, before each spin cycle, as follows:
The phase begins at a speed of 55 rpm; the speed can never fall below this threshold, otherwise the
check is repeated.
At intervals of 400 ms, the balance is calculated and compared with predetermined limits. If the value is
less than the lower limit, the speed of the drum is increased by 2 rpm; if the value is higher, the speed of
the drum is reduced by 2 rpm. The reduction in the speed of the drum distributes the washing correctly;
this procedure is repeated until the wash load is completely balanced.
Correct balancing of the wash load is achieved at a speed of 115 rpm, after which the spin cycle begins.
The Unbalancing Control function takes place in three steps:
Step 1:
The first phase has a preset unbalancing threshold: if correct balancing is achieved, the appliance
performs the spin cycle. If not, after a maximum of 60 seconds, a spin pulse at 470 rpm is
performed and the function passes to step 2.
Step 2:
In the second phase, the unbalancing threshold is variable: if correct balancing is not achieved
within 180 seconds, the function passes to step 3.
Step 3:
The third phase has a preset unbalancing threshold: if correct balancing is not achieved within 60
seconds, the spin cycle is performed at a lower speed. In this case, spinning may also start at 85
rpm.
If the unbalancing value remains excessive, the spin cycle is skipped.
Anti-foam control function
If the pressure switch detects an anti-foam level (i.e. excessive foam) at the beginning of the spin cycle, the
spin is interrupted and the appliance resumes operation from the second phase of the unbalancing control
procedure.
