Washing performance

The Ideal Wash System (IWS) is designed to wash every item perfectly the first time - 24 hours per day, 7 days a week.
The pre-wash zone typically contains the dirtiest water in the dishwasher and provides the base for perfect washing.
Unlike traditional systems, the Electrolux pre-wash is completely detached from the detergent laden heated wash
zone water and uses only fresh cold water to prevent protein based food stuffs sticking to the plates.

The wash zone is also physically separated from the rinse zone, (that in a traditional system is carried over from rinse area)
so the wash tank is free of rinse aid that typically weakens the washing power of the detergent; resulting in excessive
detergent consumption.

Even during long washing periods lasting several hours, where traditional dishwashers need to be completely drained
and re-filled at some stage, the IWS continues washing with only a minimal quantity of water being consumed.

Each machine has two pre-set speeds - slow for more baked on dirt, fast for lighter soiling; both speeds
can be fine tuned on-site via the electronic control panel to suit customer needs.

When the pre-wash or wash water becomes too dirty to wash effectively, a part of the dirty wash water is automatically
drained and replenished without stopping the dishwasher enabling continuous-all day washing. Drainage quantities and
frequencies are all variable via the electronic control panel in order to maximize washing performance with minimum water
consumption.

On 150 litre modules, the duo wash pump
configuration features one 2,2kW pump
supplying the upper wash arms, another
1,1kW pump supplying the lower wash
arms, concentrating as much high powered
wash water as possible - ideal for dried on
foods or where large number of containers
or utensils are washed.

In order to wash in the shortest possible
space, the Maximum Water Contact (MWC)

wash arms are positioned along the full
length of the wash tank. Thus doubling the

amount of wash water contact time in
comparison to traditional wash arm
configurations. Just because a basket is in
the wash zone for 2 minutes, it doesn’t
mean it is being washed in water
for 2 minutes.

Duo filter system minimises food debris
entering the wash water system, reducing
the need to regenerate water. The curtain
system prevents water splash over from
tank to tank.
