"Flexi Tabs"
The option is optimised for use of detergents which are complete with
salt and rinse aid, known on the market as, "triple action", etc. With this
option activated, any salt and rinse aid If you wish to use detergents
which already contain salt and rinse aid already in the dishwasher will
not be used.
With short programs, because there is less time for them to dissolve,
tablets may fail to wash effectively and undissolved residues may be left.
Powder detergents are more suitable for these programs.
-
IMPORTANT: when no longer required, the option must be disabled
(the light goes out).
If the water hardness has been set on a value above H3, and the "Flexi
Tabs" option is activated, the relative light flashes, warning of a setting
error. Multi-function products are not suitable for use with very "hard"
water; this does not prevent the use of the option, but the washing
results might not be of the best.
HYCLEAN
The "HYCLEAN" option prolongs the final hot rinse to ensure a further
reduction in the bacteria level. If the temperature in the tank falls during
this stage of the program (e.g. because the door is opened or due to a
power blackout), the light of the option and the program lights flash to warn
that the additional washing phase has not been completed successfully.
This does not mean that the wash program has been less effective than
usual.
SPREAD HALF LOAD
Suitable when there are not many dishes to be washed, it saves energy
and reduces the program duration. Place dishes in both baskets then
load the detergent dispenser than less than the normal amount for a full
load.
PROGRAM DELAY
The PROGRAM DELAY button can be pressed to delay the start of the
washing program by 3,6 or 9 hours. This function allows you to set the
dishwasher to work at your preferred time of day.
After selecting the delay, start the program (see relative section).
The appliance will prewash the dishes, after which the "program delay"
set previously will come into effect (light indicating the time left before the
start of the program and light indicating the program set flash).N.B.: It is
not possible to select the PROGRAM DELAY option once the cycle has
begun.
