CONTROLS INFORMATION
A single control board located at the back of the machine contains all the circuitry to control the
machine and interfaces with the programme selector, option buttons and LEDs located on the console
panel. The control board has an access port to the rear of the machine.
Programmes are selected by turning the rotary switch to one of the 16 positions. Special options can
be selected by pressing the appropriate buttons and the programme process followed by LEDs.
The machine is switched on using the On/Off button and selected programmes started by pressing the
Start/Cancel button.
Automatic Features
Auto Half Load
Auto half load adjusts the amount of water in the wash load depending on the absorbency of garments
in the wash load.
Fabric Conditioner Dispensing
Dispensing of fabric conditioner is achieved by energising both the Pre-Wash and Main Wash cold
valves.
Load Balancing System
Before every spin cycle, to avoid excessive vibrations before every spin and to distribute the load in a
uniform manner, the drum rotates continuously at a speed which is slightly greater than the washing
rotation speed. If, after several attempts, the load is not balanced correctly, the machine spins at a
reduced spin speed. If the load is excessively unbalanced, the washing machine performs the
distribution process instead of spinning. To encourage improved load distribution and balance, we
recommend small and large garments are mixed in the load.
Out of Balance Protection
The machine has an inbuilt feature to prevent spinning with an unbalanced load. A calculation via the
motor tacho and control board detects the current drawn by the motor during distribution.
Before each spin, the controls senses the load within the drum and if the load is calculated to be out of
balance the machine will not automatically spin to the full speed.
There are two levels of out of balance, level 1 @ 480 grammes and level 2 @ 1030 grammes.
If the out of balance is below level 1 the machine will spin at full speed, if between level 1 and level 2
the machine will spin at the reduced speed of 600 rpm and above level 2 spin at reduced speed of 400
rpm. There are 15 attempts at level 1 with 57 attempts in total, this being the same for both cotton and
synthetic spins.
The Wool Spin has one level of out of balance @ 1.8 kg. The controls will make three attempts to
achieve a balance, if after three attempts a balance is not achieved; the spin is reduced to a speed of
90 rpm.
