Electrolux ESF6121, Instruction Book

5

Before using your dishwasher for the first time:

1. Ensure that the electrical and water connections comply 

with the installation instructions

2. Remove all packaging from inside the appliance

3. Set the water softener

4. Pour 1 litre of water inside the salt container and then fill 

with salt

5. Fill the rinse aid dispenser

Setting the water softener

The dishwasher is equipped with a water softener designed to
remove minerals and salts from the water supply, which would
have a detrimental or adverse effect on the operation of the
appliance.
The higher the content of these salts, the harder your water is.
Water hardness is measured in equivalent scales, German
degrees, French degrees and PPM (parts per Million).
The softener should be adjusted according to the hardness of
the water in your area. Your local Water Authority can advise
you on the hardness of the water in your area.
The water softener must be set in both ways: manually, using
the water hardness switch and electronically, using the function
push buttons on the control panel.
If your water is level 1 it is already soft and therefore there
is no need to use salt.

Setting manually

1. Open the dishwasher door.

2. Remove the lower basket from the dishwasher.

3. Turn the water hardness switch to position 1 or 2 (see 

table).

4. Replace the lower basket.

The dishwasher is factory set at position 2.

Setting electronically

The dishwasher is factory set at level 3. If it’s necessary to set
a new level, proceed as follows.

1. With the dishwasher switched off press function push 

buttons 1 and 2 simultaneously .

2. While keeping the push buttons 1 and 2 pressed switch on 

the dishwasher by pressing the On/Off push button. 
The On/Off indicator light comes on. 
At the same time, the indicator lights of push buttons 1 and 
2 start flashing. 

3. Press push button 1, the indicator light of push button 2

turns off, while the indicator light of push button 1 remains 
fixed for about 5 seconds, after this it starts flashing 
indicating the current level of the water softener.
The current level is indicated by the number of flashes 
made by the indicator light of push button 1, that alternates 
5 seconds off with a number of flashes, this for about 60 
seconds.

Example:
1 flash

=

level 3

4 flashes =

level 4

5 flashes =

level 5

push button is pressed the level changes.

Examples:
if the current level is 3, by pressing push button 1 once, 
level 4 is selected.
if the current level is 5, by pressing push button 1 once, 
level 1 is selected.

The indicator light of push button 1 remains off for about 5 
seconds after which it starts flashing indicating the new 
level selected.
