Drain Pump; Detergent Dispenser - Hotpoint Ariston LFF 825 IT Service Manual

Drain Pump:

the new Drain Pump does not have a volute assembly so the wash impellers are uncovered. It must be
fitted directly to the reservoir. The drain hose too is connected directly to the reservoir and not to the Pump
as in the previous platform.
A small hole has been provided in the upper section where the Drain Pump is attached, in order to prevent
the formation of "Air Bubbles" which result in cavitation (working without pumping water).

Detergent Dispenser:

Physically and functionally identical to that of Evo 3. With double catch system; the first catch for opening
the cover and the second (double) for adding rinse aid.
Anti-flood float:
Functionally identical although physically different to that used in Evo 3.
From an electrical point of view, it is normally closed, (unlike EVO3).
When activated by water in the pan (switch electrically open), the dishwasher will drain and activate an
"Overflow" alarm.
Filters:
There are 3 filters: the first (1) is made of steel and is flat, much larger than those in the previous platform
in order to prevent it becoming easily clogged.
The second (2) is a basket filter, similar to that on the previous platform; and the third (3), the microfilter,
which in this case does not rotate but is fixed.
In order to exploit the entire filtering surface of these last two filters, a small "spoiler" has been fitted inside
the reservoir to direct water from all areas to the filters.
Other components
The other components, although physically different, perform the same functions as they did in
the previous platform (Evo 3). This does not mean that they are interchangeable, since technical
characteristics will differ (for example: the pressure switch).
