4. Installation
4-1.Positioning the appliance
Positioning the appliance in the desired location. The back should rest against the wall behind it,
and ts, along the adjacent cabinets or wall. The dishwasher is equipped with water supply and
drain hoses that can be positioned to the right or the left to facilitate proper installation.
4-2.Leveling the appliance
Once the appliance is positioned, adjust the feet (screwing them in or out) to adjust the
dishwasher,making it level. In any case, the appliance should not be inclined more than 2°. If the
appliance is level, it will help ensure proper performance.
4-3.Cold water connection
Connect the water supply hose to a threaded 3/4 (gas) connector,
making sure that it is fastened tightly in place (DWF1250P/DWP5012WA/
DWP4912W see fig.A).
Some models are fitted with an "Aquastop" water supply hose
(DWP4915SL see fig.B) in which the small filter is already housed
in the threaded end.
If the water pipes are new or have not been used for an extended
period of time, let the water run to make sure that the water is
clear and free of impurities. If this precaution is not taken, there
is a risk that the water inlet can get blocked and damage the
appliance.
4-4.Anti-Flooding protection
The dishwasher is equipped with a system that stops the supply of water in the event of a problem
with the water supply hose or leaks within the unit, in order to prevent damage to your home. If for
any reason the box containing the electrical components happens to get damaged, turn off the
power supply and unplug the appliance immediately. In order to guarantee that the anti-flooding
feature operates properly, box "A" with the water supply hose must be attached to the water
supply tap as shown in Fig. B. If the length of the hose is not adequate to make a proper
connection, the hose must be replaced with one which is long enough. This hose is available
upon request from specialised retailers and approved service centres.
4-5.Drain hose connection
Insert the drain hose into a drain pipe with a minimum diameter of 4cm, or let it run into the sink,
making sure to avoid bending or crimping it. If necessary, fit a syphon trap (U-bend) with a
connecting piece for the drain hose (fig.C). The free end of the hose must be at a height between
40 and 100 cm and must not be immersed in water.
Warning:
The appliance is to be connected to the mains water using new hose sets. Old hose
sets should not be reused.

4-6.Electrical Connection
After making sure that the voltage and frequency values for the current in the home correspond to
those on the rating plate (located on the stainless steel inner door of the appliance) and that the
electrical system is correct for the maximum voltage on the rating plate, insert the plug into an
electrical socket which is earthed properly (the earthing of the appliance is a safety requirement
mandated by law).If the electrical socket to which the appliance must be connected is not
appropriate for the plug, replace the whole cable, rather than using adaptors or the like as they
could cause overheating and burns.
Electrical Connection (Uk Only)
For your safety please read the following information.
Warning: This appliance must be earthed.
The appliance must be connected to a 220-240 volts 50 cycle AC supply by means of a three pin
socket, suitably earthed and should be protected by a 13 amp fuse in the plug.
The appliance is supplied with a rewireable 13 amp 3-pin plug fitted with a 13-amp fuse. Should
the fuse require replacement, it must be replaced with a fuse rated at 13 amp and approved to
BS1362.
If the mains plug is unsuitable for the socket outlet in your home or is removed for any other
reason,then the cut off plug should be disposed of safely to prevent the hazard of electric shock.
Remove the fuse before disposal.
There is a danger of electric shock if the cut off plug is inserted into any 13-amp socket outlet.
Caution:
The dishwasher plug must be accessible even when the appliance is installed as a
built-in unit so that maintenance can be done safely.
Attention:
The connecting piece for syphon trap (U-bend) must be solidly fastened to the wall to
prevent the drain hose from moving and allowing water to spill outside the drain.

6. How to fill the salt
6-1.Salt
The hardness of the water varies from place to place. If hard water is used in the dishwasher,
deposits will form on the dishes and utensils.
The appliance is equipped with a special softener that uses a salt specifically designed to
eliminate lime and minerals from the water.
6-2.Loading the salt into the container
Always use salt intended for use with dishwashers.
The salt container is located beneath the lower rack and should be filled as follows:
According to the “Water Hardness Tabel”, you can calculate
the time of use, then load the salt .
Remove the lower rack and then unscrew and remove
the cap from the salt container.
If you are filling the container for the first time, fill it with
water.
Place the end of the funnel (supplied) into the hole and
introduce about 2 kg of salt. It is normal for a small amount
of water to come out of the salt container.
Carefully screw the cap back on.
6-3.Adjusting salt consumption
The dishwasher is designed to allow for adjusting the amount of salt consumed based on the
hardness of the water used.This is intended to optimize and customize the level of salt
consumption so that it remains at a minimum.
To adjust salt consumption, proceed as follows:
Unscrew the cap from the salt container;
There is a ring on the container with an arrow on it
(see figure to the side),
If necessary, rotate the ring in an anticlockwise direction
from the "-" setting towards the "+" sign, based on the
hardness of the water being used.
It is recommended that adjustments be made in accordance with the following table:
Important：
To prevent the formation of rust, load the salt just before beginning a wash cycle.

7. How to fill rinse aid
7-1.Rinse aid
This product makes dishes sparkle and helps them to dry without spotting. The dispenser is
located on the inside panel of the door .
When the low rinse aid indicator “ 1 ” is bright, it means the
rinse aid is low, you must load rinse aid .
7-2.Loading the rinse aid
Regardless of the type of detergent dispenser installed on
your appliance, you must proceed as indicated below when
loading the rinse aid.
To open the dispenser, turn the "2" cap in an anti-clockwise
direction and then pour in the rinse aid, making sure not to
overfill. The amount of rinse aid used for each cycle can be
regulated by turning the " 3" dose adjustor, located beneath
the "2" cap, with a screwdriver. There are 6 different settings;
the normal dosage setting is 3.
Important：
Proper dosage of the rinse aid improves drying.

the dosage adjuster should be turned to a higher setting.
If the dishes have white streaks, turn the dosage adjuster
to a lower setting.
