6 Maintenance and cleaning
Service life of the product extends and 
frequently faced problems decrease if 
cleaned at regular intervals.
Cleaning the detergent drawer
Clean the detergent drawer at regular 
intervals (every 4-5 washing cycles) 
as shown below in order to prevent 
accumulation of powder detergent in 
time.
1.  Press the dotted point on the siphon 
in the softener compartment and pull 
towards you until the compartment is 
removed from the machine.
C If more than normal amount of water 
and softener mixture starts to gather 
in the softener compartment, the 
siphon must be cleaned.
2.  Wash the detergent drawer and the 
siphon with plenty of lukewarm water 
in a washbasin. Wear protective 
gloves or use an appropriate brush to 
avoid touching of the residues in the 
drawer with your skin when cleaning.
3.  Insert the drawer back into its place 
after cleaning and make sure that it is 
seated well.
Cleaning the loading 
door and the drum
Residues of softener, detergent and 
dirt may accumulate in your machine in 
time and may cause unpleasant odours 
and washing complaints. To avoid this, 
use the Drum Cleaning programme. If 
your machine is not featured with Drum 
Cleaning programme, use Cottons-90 
programme and select Additional Water 
or Extra Rinse auxiliary functions as well. 
Before starting the programme, put 
max. 100 g of powder anti-limescale into 
the main wash detergent compartment  (compartment nr. II). If the anti-limescale 
is in tablet form, put only one tablet into 
compartment nr. II. Dry the inside of the 
bellow with a clean piece of cloth after the 
programme has come to an end. 
C 
Repeat Drum Cleaning process in 
every 2 months.
C Use an anti-limescale suitable for the 
washing machines. 
After every washing make sure that no 
foreign substance is left in the drum.
If the holes on the bellow shown in the 
figure is blocked, open the holes using a 
toothpick.
C  Foreign metal substances in your 
machine will cause rust stains. Clean 
the stains on the drum surface by 
using cleaning agents for stainless 
steel. Never use steel wool or wire 
wool.
Cleaning the body 
and control panel
Wipe the body of the machine with 
soapy water or non-corrosive mild gel 
detergents as necessary, and dry with a 
soft cloth.
Use only a soft and damp cloth to clean 
the control panel.
A Never use sponge or scrub materials. 
These will damage the painted and 
plastic surfaces.
Cleaning the water intake filters
There is a filter at the end of each water 
intake valve at the rear of the machine 
and also at the end of each water 
intake hose where they are connected 
to the tap. These filters prevent foreign 
substances and dirt in the water to enter 
the washing machine. Filters should be   
						

							29EN
cleaned as they do get dirty.
1. Close the taps.
2.  Remove the nuts of the water intake 
hoses to access the filters on the 
water intake valves. Clean them with 
an appropriate brush. If the filters are 
too dirty, take them out by means of 
pliers and clean them.
3.  Take out the filters on the flat ends of 
the water intake hoses together with 
the gaskets and clean thoroughly 
under running water.
4.  Replace the gaskets and filters 
carefully in their places and tighten the 
hose nuts by hand.
Draining remaining water and 
cleaning the pump filter
The filter system in your machine prevents 
solid items such as buttons, coins and 
fabric fibers clogging the pump impeller 
during discharge of washing water. Thus, 
the water will be discharged without any 
problem and the service life of the pump 
will extend.
If the machine fails to drain water, the 
pump filter is clogged. Filter must be 
cleaned whenever it is clogged or in every 
3 months. Water must be drained off first 
to clean the pump filter.
In addition, prior to transporting the 
machine (eg., when moving to another 
house) and in case of freezing of the 
water, water may have to be drained 
completely.
A Foreign substances left in the pump 
filter may damage your machine or 
may cause noise problem.
In order to clean the dirty filter and 
discharge the water:
1.  Unplug the machine to cut off the 
supply power.
A Temperature of the water inside the 
machine may rise up to 90 ºC. To 
avoid burning risk, filter must be 
cleaned after the water in the machine 
cools down.
2.  Open the filter cap.
  If the filter cap is composed of two 
pieces, press the tab on the filter cap 
downwards and pull the piece out 
towards yourself.
If the filter cap is one piece, pull the cap 
from both sides at the top to open.
C You can remove the filter cover by 
slightly pushing downwards with a 
thin plastic tipped tool, through the 
gap above the filter cover. Do not 
use metal tipped tools to remove the 
cover.
3.  Some of our products have 
emergency draining hose and some 
does not have. Follow the steps 
below to discharge the water.
Discharging the water when the product 
has an emergency draining hose:  
						

							30EN
a. Pull the emergency draining hose out 
from its seat
b.  Place a large container at the end 
of the hose. Drain the water into 
the container by pulling out the plug 
at the end of the hose. When the 
container is full, block the inlet of 
the hose by replacing the plug. After 
the container is emptied, repeat the 
above procedure to drain the water in 
the machine completely.
c.  When draining of water is finished, 
close the end by the plug again and 
fix the hose in its place.
d.  Turn the pump filter to take it out.
Discharging the water when the product 
does not have an emergency draining 
hose:
a.  Place a large container in front of the 
filter to catch water from the filter.
b.  Loosen pump filter (anticlockwise) 
until water starts to flow. Fill the 
flowing water into the container 
you have placed in front of the filter. 
Always keep a piece of cloth handy to 
absorb any spilled water.
c.  When the water inside the machine is 
finished, take out the filter completely 
by turning it.
4.  Clean any residues inside the filter as 
well as fibers, if any, around the pump 
impeller region.
5.  Install the filter.
A If your product has a water jet feature, 
be sure to fit the filter into its housing 
in the pump. Never force the filter  while installing it into its housing. Seat 
the filter into its place completely. 
Otherwise, water may leak from the 
filter cap.
6.  If the filter cap is composed of two 
pieces, close the filter cap by pressing 
on the tab. If it is one piece, seat the 
tabs in the lower part into their places 
first, and then press the upper part to 
close.
