Issue
Formation of foam inside
the tank during a cycle.
Stains on interior
surfaces.
The dishes are not clean.
Possible causes
Inappropriate detergent.
Soil that generates foam.
Limescale may appear on the
surfaces.
I live in an area with very hard
water.
The dishes are not placed
correctly in the basket.
The selected wash program is
unsuitable.
Insufficient amount of
detergent, or unsuitable
detergent.
The spray arm is blocked by
dishes.
One or more of the spray arm
nozzles is/are clogged.
The filter are not clean or are not
correctly arranged.
Known solutions
Only avoid special dishwasher
detergent to avoid foaming. However,
if this happens, open the dishwasher
door and
allow the foam to evaporate.
Close the door and start a wash
program to drain the water. Repeat
the procedures if necessary.
Different types of soil generate more
or less foam. However, if there is too
much foam during a cycle it can
block the spray arm. In this case,
empty the basket and run an empty
cycle before you start washing your
dishes again.
Run a maintenance cycle at least
once every 90 cycles with a rock'n'roll
cassette (refer to page 20)
We recommend to use Bob Tablette
instead of Bob cassette and run a
maintenance cycle with a rock'n'roll
cassette more frequently (every 30
cycles).
Avoid any contact between the
different items in the basket. Please
refer to page 10: Recommendations
for the arrangement of the dishes in
the basket.
Choose a more intensive program.
Refer to page 15: Standard programs
We recommend to use a Bob
Tablette
Change the arrangement of the
dishes so that the spray arm can
rotate freely.
Disassemble and clean the spray arm
as described on page 21
Disassemble and clean the filters as
described on page 18.
