A) SAFETY PRECAUTIONS
Before intervention on any internal components, always remove the power plug from
the socket.
When possible, the ohmic resistance of the components should be measured rather
than making direct measurements of voltage and current.
Some parts of the mechanical structure of the appliance could be dangerous; it is
necessary to take care in order to avoid injuries.
B) PURPOSE OF THIS MANUAL
This manual is to provide technicians, who have already a basic knowledge of repairing washing
machines, with general information concerning this new range of products.
For more detailed information refer to:
- electrical diagram
- programming
- spart parts list
C) PRESENTATION OF APPLIANCES
This new range of washing machines consists of:
- A CARBORANâ base including the filter body on which different components are fixed
(drain pump, circulation pump, inlet valve, module and suspension).
- A tub of CARBORANâ and a drum of stainless steel with a capacity of 42 liters.
On the tub there are compensating weights, one left and one right, and electrical
components such as heating element, thermostat, motor and cables.
- A cabinet including four side panels:
• right, left and front panels electrogalvanized and thermolacquered;
• rear panel electrogalvanized
On this construction the tub is hanging up by four springs.
- A top of “polypropylene”, a housing lid on which the water inlet tray is fixed, a functional
support including the control panel with the electrical components and the water
distributor.

a) Advantages of the “Direct Spray” function
The “direct spray” function with a spraying system in the middle of the drum offers a
high performance of washing and rinsing to the user with a low consumption of water
andenergy.
“Direct Spray” principle:
- During the filling the circulation pump function permits to moisten quickly the
washing and thus to optimize the amount of water following the quantity and
kind of washing.
- During the washing cycle the circulation of washing water permits a
continuous spraying. This operation combined with the mechanical effect of
the drum rotation permits to obtain a very high performance of wash.
- The circulation with foam control will also be used during the rinsing cycles to
optimize the water consumption.
b) Principle
The circulation pump brings the wash water from the drum to the left bearing, then
this water is injected through the holes in the drum (2).

3) ”ECO”-washing system
a) Advantages of the “ECO” function
Due to the „ECO“ washing systems, with the ECO-ball in the durit-hose, the user
achieves a high washing and rinsing result with a low consumption of detergent.
The detergent does not fall down as far as to the drain area during the filling cycle,
but remains on the ECO-ball usable for the washing cycle.
b) Principle
During the filling cycle, a part of the water is conducted through the hose (9) into the
fluff filter housing.
The water level in the fluff filter housing increases until the ECO-ball floats up in the
durit hose and locks the way to the tub (see figure).
ECO-ball Durit hose
The further existing water pressure is passed on through the hose (12) into the tub.
When selecting the drain pump, the ECO-ball is drawn downwards because of the
underpressure, the water in the tub can be drained.

4) ”ECO”-washing system with nozzle
a) Advantages of the “ECO” function
Due to the „ECO“ washing systems, with the ECO-ball in the durit-hose, the user
achieves a high washing and rinsing result with a low consumption of detergent.
The detergent does not fall down as far as to the drain area during the filling cycle,
but remains on the ECO-ball usable for the washing cycle.
b) Principle
During the filling cycle, a part of the water is conducted through the hose (9) into the
fluff filter housing. The water quantity inflow is dosed via a nozzle. This is located in
the hose (9) approximately 5 cm beneath the water distributor
The water level in the fluff filter housing increases until the ECO-ball floats up in the
durit hose and locks the way to the tub (see figure).

underpressure, the water in the tub can be drained.

Both bearings are screwed on the tub (1).
The bearing (7) is pressed into a metallic insert.
The bearing is sealed as follows:
- The gaskets (6) to the shaft are set into the bearing body. The bearing seat permits to
obtain a perfect concentricity between the bearing (7) and the gasket (6), which
guarantees a perfect sealing.
- The bearing seat on the tub is sealed by a gasket (2).

*) Attention!
The flushing into the prewash chamber goes via hose 4.
The flushing into the main wash chamber goes via hose 2.
The simultaneous filling through hoses 2 and 4 provides the fill-in through the softener chamber.
*) Attention!
The flushing into the prewash resp. bleach chamber goes via hose 4.
This is possible due to a connecting channel in the flush-in chamber.
In doing so, approx. 75% water flows into the prewash chamber and aprox. 25% into the
bleach chamber.
It is not possible to select both options prewash and bleaching at the same time.
The flushing into the main wash chamber goes via hose 2.
The simultaneous filling through hoses 2 and 4 provides the fill-in through the softener chamber.
