Detergent
To fill the detergent compartment
• Push the latch to open the
compartment.
• Add the required amount of detergent.
The main detergent compartment “b”
(Fig. 2) has lines to allow for specific
amounts of detergent. These are marked at either 15cm3or 25cm3, to
be used depending on how dirty the dishes are.
If your dishes are in need of an intensive wash, then add 5cm3of
detergent into the prewash section of the compartment “a” (Fig. 2).
• Close the detergent compartment lid until the latch locks.
Please note: You should only use detergents designed specifically
for use in dishwashers.
If using dishwasher tablets, always use the detergent compartment,
do not put them in the main body of the dishwasher or in the cutlery
basket. The solubility of dishwasher tablets can vary depending
on the temperature and duration of the programme. As a result, it is
recommended that powder detergents should be used in the shorter
programmes to allow better performance.
The use of separate detergent, rinse aid and dishwasher salt is
recommended rather than combination tablets as separates achieve
better wash performance.
If you do use combination detergents, add salt and rinse aid to the
dishwasher and then adjust the water hardness setting and rinse aid

the programme. As a result, it is recommended that powder detergents should
be used in the shorter programmes to allow better performance.
CDA recommends the use of separate detergent, rinse aid and dishwasher salt
rather than combination tablets as separates achieve better wash performance.
If you do use combination detergents, add salt and rinse aid to the dishwasher
and then adjust the water hardness setting and rinse aid setting to the
minimum. When you then use separate detergents again, you should fill the
salt and rinse aid compartments, adjust the water hardness setting to the
maximum and run an empty wash, then adjust the water hardness setting and
the rinse aid setting to the appropriate level.
Salt
To ensure the best efficiency, the dishwasher needs soft water. Hard water
means that lime residues remain on the dishes and the interior of the
dishwasher, affecting performance. The softener system is designed to
remove the ions that make the water hard to provide the best quality wash
performance. This is achieved by using dishwasher salt.
To add dishwasher salt, follow the steps below:
1. Remove the lower dishwasher basket and then unscrew the salt
compartment cap, as shown in figure 1.
2. Fill the compartment with dishwasher salt (do not use table salt), carefully
to prevent unnecessary spillage (figure 3). Before first use, you should
fill the compartment with 2kg of dishwasher salt and then fill up the salt
compartment with water (up to the brim of the compartment) as shown
in figure 3.
3. Replace the cap and the lower basket.
When the salt warning light on the control panel illuminates, you should
refill the salt compartment with salt only – do not add water to the salt
compartment after the first use.
You should run a prewash programme immediately after adding
dishwasher salt, to prevent any damage to the dishwasher systems.

Important:
You should run a prewash programme immediately after adding
dishwasher salt, to prevent any damage to the dishwasher system.
Softener Adjustment
The efficiency of your dishwasher depends on the softness of the
tap water. To ensure best efficiency, the dishwasher is equipped with
a system that reduces the hardness in the mains water supply. The
efficiency will increase when the system is correctly set. To find out the
water hardness level of your water supply you can use the test strip
supplied, or alternatively contact your local water board.
• Open the testing strip (Fig. 5).
• Run water through the tap for one minute.
• Hold the testing strip in water for one second.
• Remove from the water and shake the test strip to remove excess
water.
• Wait for one minute.
• Check the number of marks on the strip to see the level of water
hardness.
Fig. 5

12
If the hardness of the water you use is above 63dE, or if you are using
well water, you are recommended to contact your local water board to
confirm the water hardness level and to use filter and water refinement
devices.
Please note: The water hardness is preset to level “3”.
To change the hardness setting
• Press and hold down the “Programme Selection” button.
• Press the “Power” button to switch on the dishwasher.
• Keep the “Programme Selection” button pressed until all “Programme
Indicator” lights and the “End of Programme” indicator light flash.
• To adjust the level, press the “Programme Selection” button until the
required level is shown on the display: The “Programme” lights will
illuminate as in the table below.
• To store the selected water hardness level, press the “Power” button.
Rinse aid
Rinse aid helps to ensure better quality wash results and increased
drying performance.
To fill the rinse aid compartment, open the rinse aid compartment lid.
Fill the compartment with rinse aid to the MAX level and then close the
lid. Be careful not to overfill the rinse aid compartment and ensure that
you wipe up any spillages.
