How the dishwasher works (overview)
To be able to effectively service the dishwasher it is necessary to understand how it has been
designed to operate. The following is an overview of the dishwashers operation:
When checking a program always cancel any previous program by turning the unit on, then holding
down the Start/Stop button for three seconds. Then select the program to be checked.
All components are activated from the control unit, however other actions may have to take place first
before a component is activated (for example the heater will not come on if there is no water in the
machine).
All programs begin with a
25 second drain
. The drain pump is partially self-cleaning due to the fact
that the direction of rotation is random. The entire contents of the tub should drain out within that 25
seconds. If not either the filters are not clean, or there is an obstruction in the drain pump, the hose,
the disposal or air break.
Note: It is normal to have some water visible beneath the filters.
The unit
fills with water
via a solenoid operated fill valve controlled by a flow meter or timed fill. The
fill is monitored by a pressure switch which will respond if there is not enough water (for example a
bowl tips over retaining a good volume of water) or if the machine should overfill, by turning on the
drain pump.
The
circulation motor/pump
forces the water into the two (three) spray arms directly, or via the water
diverter to each spray arm in turn. The motor is capacitor start.
The
water diverter
has a synchronous motor that drives a disc valve via a gearbox and controls the
water to each spray arm.
The water is heated
via a flow through tubular heater suspended between the sump housing and the
Circulation pump. The heater is protected by an auto reset thermal cut-out, and a thermal fuse.
